Não existe nenhum dente especializado na injeção de veneno, no entanto a mordida das jibóias, por exemplo, é bastante dolorosa e a saliva infectada por bactérias, podendo levar a uma infecção daquelas. &lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;span class=&quot;Apple-style-span&quot; style=&quot;color: rgb(0, 0, 238); -webkit-text-decorations-in-effect: underline; &quot;&gt;&lt;img src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiIKNuWyQ3R2sN4VqceRjbirek2-dG4mNIbqcNVVxTzKhUoGKfm6BnvxmdQXySrWb1GUVzkjFhzKOsKEnZ-lWKqqnLrBTCDt91TA6_7hHmR5lUDp8a_Uc2W5nCP-MzoWBsJdm-niz7KJJA/s320/%C3%A1glifa.jpg&quot; border=&quot;0&quot; alt=&quot;&quot; id=&quot;BLOGGER_PHOTO_ID_5503588613166949026&quot; style=&quot;float: left; margin-top: 0px; margin-right: 10px; margin-bottom: 10px; margin-left: 0px; cursor: pointer; width: 224px; height: 198px; &quot; /&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span class=&quot;Apple-style-span&quot; style=&quot;color: rgb(0, 0, 238); -webkit-text-decorations-in-effect: underline; &quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;img src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjbiN0y8R7OEr_4DERL3FXgCaMCKtNjYJv38LmEjSdV5ImdnIpmncJed-8p0Q8Kgmh3Q2a5wXYowumkJQosWG-fQrgiwll6feZLvMkj3uf9GB0lH54bLRVFreXH1fSU17u4CSE-SWUqtXk/s320/images+(1).jpg&quot; style=&quot;display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 251px; height: 201px;&quot; border=&quot;0&quot; alt=&quot;&quot; id=&quot;BLOGGER_PHOTO_ID_5503202604782325266&quot; /&gt;&lt;b&gt;&lt;br /&gt;&lt;/b&gt;&lt;/div&gt;&lt;div&gt;&lt;b&gt;&lt;br /&gt;&lt;/b&gt;&lt;/div&gt;&lt;div&gt;&lt;b&gt;Dentição Opistóglifa&lt;/b&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;Aqui existem um ou dois pares de dentes posicionados na parte posterior do maxilas (opis=oppositu).

Adiantei que o termo correto para algumas serpentes é peçonhenta, uma vez que elas produzem e são capazes de injetar o veneno na presa.&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;Mas qual a diferença então entre venenosa e peçonhenta? &lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;É justamente a capacidade de inocular o veneno. Uma planta, por exemplo, é considerada venenosa se produzir substâncias tais que, ao serem ingeridas, tiverem a capacidade de intoxicar e eventualmente matar, e no entanto ela não é peçonhenta.&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;Outro exemplo do reino animal são alguns  sapos e rãs como a &lt;i&gt;Dendrobates pumilio&lt;/i&gt; (foto) considerada um dos animais mais venenosos do planeta e no entanto não é peçonhenta, uma vez que só causa algum mal se for ingerida.&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;span class=&quot;Apple-style-span&quot; style=&quot;color: rgb(0, 0, 238); -webkit-text-decorations-in-effect: underline; &quot;&gt;&lt;img src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgm9AwH_zsFwkkFlWddXreIloyl-agFO0G0ehF9CFEAFyO-PiMwDaGvbl4IKxE49Q5sGxRbwv9c0wCb8TGptQPTszlA7lOvWY3x_3v54lX6tVJOYowxeitStsgu9ki1OLF8-YE1DzAW61g/s320/138906.jpg&quot; border=&quot;0&quot; alt=&quot;&quot; id=&quot;BLOGGER_PHOTO_ID_5495358609271876914&quot; style=&quot;text-align: justify;float: left; margin-top: 0px; margin-right: 10px; margin-bottom: 10px; margin-left: 0px; cursor: pointer; width: 320px; height: 213px; &quot; /&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;As serpentes peçonhentas estão classificadas em quatro famílias, Elapidae (corais e najas), Viperidae (cascavéis e jararacas), Atractasapididae (víbora serrilhada) e Colubridae* (cobra rateira) e todas possuem um aparelho produtor/injetor de veneno.&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;O veneno é produzido e armazenado em  glândulas que se encontram na porção da musculatura supralabial do animal atrás ou abaixo dos olhos. As glândulas de veneno, que acredita-se serem uma evolução das glândulas salivares, podem ser de duas formas dependendo da família a qual a serpente pertence.&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;As famílias Viperidae, Elapidae e Atractaspididae possuem um par de glândulas em forma de bolsa ou lúmen onde o veneno é produzido e armazenado. Esse tipo de glândula está ligada a um músculo que é contraído no momento da picada. Com a contração muscular a glândula é pressionada e libera seu conteúdo rapidamente.&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;Já as serpentes peçonhentas da família Colubridae possuem um aparato chamado glândula de Durvenoy. Essa glândula se encontra fixa pelo tecido conjuntivo ligada à musculatura do maxilar. Aqui o veneno não fica armazenado no lúmen mas dentro das células do tecido e no momento da picada, o ligamento com o musculatura do maxilar contrai a glândula e faz com que o veneno seja liberado gradualmente pelas células, e então &quot;escorre&quot; pelos dentes da serpente.&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;Assim à primeira vista não parece haver muita diferença, mas esses dois tipos de &quot;aparelhagem&quot; de liberação do veneno fazem toda a diferença na hora da picada. No primeiro caso, como o veneno já está lá armazenado, em uma única picada a serpente pode liberar uma grande quantidade de veneno e depois ficar à espreita esperando a presa morrer. &lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;Por outro lado, os colubrideos precisam ficar em contato com a presa, ou seja, picar e ficar com o animal na boca por algum tempo para que seja injetada uma grande quantidade de veneno.&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;Essa é uma vantagem que as serpentes das três primeiras famílias possuem e que as tornam muito eficientes no quesito &quot;caçada&quot;. Mas existe ainda outro fator importante para essa grande eficiência que é o tipo de dentição, mas esse vai ser assunto pra outro post.&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;Espero que tenham gostado...see ya!&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://snakesonmyblog.blogspot.com/feeds/687286060203159155/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://snakesonmyblog.blogspot.com/2010/07/venenosa-ou-peconhenta-como-disse-no.html#comment-form' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/377456641497601395/posts/default/687286060203159155'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/377456641497601395/posts/default/687286060203159155'/><link rel='alternate' type='text/html' href='http://snakesonmyblog.blogspot.com/2010/07/venenosa-ou-peconhenta-como-disse-no.html' title=''/><author><name>Butterfly</name><uri>http://www.blogger.com/profile/17508203689678794764</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='21' height='32' src='//blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgvpuMNPU0tCg1j8oUJUtQo8GC7-CR8Uc7Z5J8i_g7MVFmt-D8ewEiGZZ_h2GCAON364KswDhR9oaQoCAaQbYu6gNysdaA7tB_RPM27c4CPmOAi2LlVXosEjV3bbklxc4w/s220/842950_10200459130982171_1414319782_o.jpg'/></author><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi5gXlcH8NQnzfxTS65f_C1Tm4YioEOyMQsCt3RkDdJJTMgg0BHZo0mLHIdLo2tX1yxeTifW3uhSHv-JgUOCjq6k5E3tWlX0MW994RkLMsRmvzwgi2a2bAAwrOROOmRTXGgxgXbjFDK2i8/s72-c/1233606589_serpente_venenosa.jpg" height="72" width="72"/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-377456641497601395.post-9059747232659330437</id><published>2010-07-15T23:48:00.001-03:00</published><updated>2010-07-18T14:56:42.219-03:00</updated><title type='text'></title><content type='html'>&lt;a onblur=&quot;try {parent.deselectBloggerImageGracefully();} catch(e) {}&quot; href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh2uloJRj6KEjcZPz-OkgvqdIlXRRB4HvpuDQocU1x9k4IRo3kpNqjhB3IDMx4pV5qVZNwgRkGn2iS0QU0h4fVij3RmsSzZyetF4xZTlC-GakVrouuYLToCDBH56PLraBjyTLb53NhUgm0/s1600/naja2.jpg&quot;&gt;&lt;/a&gt; &lt;a onblur=&quot;try {parent.deselectBloggerImageGracefully();} catch(e) {}&quot; href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgg98TwmsPI3_teTSfQC8k0zBMJ-n7fV4VjQdQESBh-uhM_pvgIs4kGvoH2oh5ggp0aUXDXXuhwxHPgx_rX-_zl5RtvZG1NC-I7_5Iz2Y-Lz5O3Lw086-TujAv6YZ5r7KEM3OAANFZ27QY/s1600/python.png&quot;&gt;&lt;img style=&quot;display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 267px; height: 235px;&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgg98TwmsPI3_teTSfQC8k0zBMJ-n7fV4VjQdQESBh-uhM_pvgIs4kGvoH2oh5ggp0aUXDXXuhwxHPgx_rX-_zl5RtvZG1NC-I7_5Iz2Y-Lz5O3Lw086-TujAv6YZ5r7KEM3OAANFZ27QY/s320/python.png&quot; border=&quot;0&quot; alt=&quot;&quot; id=&quot;BLOGGER_PHOTO_ID_5494362556536058722&quot; /&gt;&lt;/a&gt;&lt;div style=&quot;text-align: center;&quot;&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style=&quot;text-align: center;&quot;&gt;&lt;span class=&quot;Apple-style-span&quot;  style=&quot;color:#0000EE;&quot;&gt;&lt;u&gt;&lt;br /&gt;&lt;/u&gt;&lt;/span&gt;&lt;/div&gt;&lt;br /&gt;&lt;b&gt;O BÁSICO&lt;/b&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;p class=&quot;MsoNormal&quot; style=&quot;text-align:justify&quot;&gt;&lt;span style=&quot;font-family:Arial;&quot;&gt;Quando se fala em serpentes, ou melhor, em cobras como popularmente as serpentes são conhecidas, a primeira reação das pessoas em geral é  um misto de medo com asco.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;  &lt;p class=&quot;MsoNormal&quot; style=&quot;text-align:justify&quot;&gt;&lt;span style=&quot;font-family:Arial;&quot;&gt;Desde criança aprendemos que cobras são feias e perigosas. Mais tarde em aulas de ciência ou biologia aprendemos entre outras coisas que elas são répteis, animais de sangue frio, rastejam e que algumas são venenosas. &lt;/span&gt;&lt;/p&gt;&lt;p class=&quot;MsoNormal&quot; style=&quot;text-align:justify&quot;&gt;&lt;span style=&quot;font-family:Arial;&quot;&gt;Recentemente algumas pesquisas sugerem que o medo de serpentes está “impresso” em nossos genes, já que elas co-evoluíram com primatas, sendo o primeiro predador a apresentar perigo grave para os mamíferos modernos, enquanto que outros predadores em potencial como leões evoluíram depois.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;  &lt;p class=&quot;MsoNormal&quot; style=&quot;text-align:justify&quot;&gt;&lt;span style=&quot;font-family:Arial;&quot;&gt;Com todo esse histórico não é de admirar que a maioria das pessoas tenha a mesma reação diante desses seres. Sim são animais potencialmente perigosos, mas partindo do principio que são desprovidos de membros, têm a visão ruim, não possuem ouvido externo, e, no entanto estão na terra há mais tempo do que nós &lt;i style=&quot;mso-bidi-font-style:normal&quot;&gt;Homo sapiens&lt;/i&gt;, no mínimo são animais que merecem ser estudados pelo seu sucesso evolutivo. &lt;/span&gt;&lt;/p&gt;&lt;p class=&quot;MsoNormal&quot; style=&quot;text-align:justify&quot;&gt;&lt;span style=&quot;font-family:Arial;&quot;&gt;Eu sempre fui fascinada por esses animais e esse blog é tentar passar um pouquinho do que aprendi.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;  &lt;p class=&quot;MsoNormal&quot; style=&quot;text-align:justify&quot;&gt;&lt;span style=&quot;font-family:Arial;&quot;&gt;Taxonomicamente serpente é o nome genérico da subordem de répteis próximos dos lagartos com os quais compartilha a mesma ordem. Acredita-se que as serpentes originaram-se a partir dos lagartos, mais precisamente dos grandes lagartos da família &lt;i style=&quot;mso-bidi-font-style:normal&quot;&gt;Varanidae&lt;/i&gt;, cujo representante mais conhecido é o dragão-de komodo. &lt;/span&gt;&lt;/p&gt;&lt;p class=&quot;MsoNormal&quot; style=&quot;text-align:justify&quot;&gt;&lt;span style=&quot;font-family:Arial;&quot;&gt;&lt;span class=&quot;Apple-style-span&quot;  style=&quot; ;font-family:Georgia, serif;&quot;&gt;&lt;img src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhXs_LUnWzIxz3WsO8LuFkpIOSsN_Q9maCSf5jLqo16GIHajfbo4gMNEzTk_DYyyLyyy5DczFuGganL5OwY5cVu-mgBH22MfcqyfYgoGivh2IkBp2bIi77Gw5Q6xrFiFad_jXB6LMMWjMk/s320/komodo2.jpg&quot; border=&quot;0&quot; alt=&quot;&quot; id=&quot;BLOGGER_PHOTO_ID_5494366114627820546&quot; style=&quot;display: block; margin-top: 0px; margin-right: auto; margin-bottom: 10px; margin-left: auto; text-align: center; cursor: pointer; width: 292px; height: 280px; &quot; /&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;&lt;div&gt;&lt;span style=&quot;font-family:Arial;&quot;&gt;&lt;span class=&quot;Apple-style-span&quot;  style=&quot; ;font-family:Georgia, serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;&lt;p class=&quot;MsoNormal&quot; style=&quot;text-align:justify&quot;&gt;&lt;span style=&quot;font-family:Arial;&quot;&gt;O “sangue frio” desses animais é devido ao fato de, como todo réptil, não serem capazes de regular a temperatura corporal, necessitando de uma fonte de calor externa e por essa razão, ocorrem em todo o planeta exceto em regiões polares.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;  &lt;p class=&quot;MsoNormal&quot; style=&quot;text-align:justify&quot;&gt;&lt;span style=&quot;font-family:Arial;&quot;&gt;Cobras na verdade são indivíduos da família &lt;i style=&quot;mso-bidi-font-style:normal&quot;&gt;Elapidae&lt;/i&gt;, uma das quatro famílias de serpentes peçonhentas existentes, sendo os representantes mais famosos as najas.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;&lt;p class=&quot;MsoNormal&quot; style=&quot;text-align:justify&quot;&gt;&lt;span style=&quot;font-family:Arial;&quot;&gt;&lt;span class=&quot;Apple-style-span&quot;  style=&quot; color: rgb(0, 0, 238); -webkit-text-decorations-in-effect: underline; font-family:Georgia, serif;&quot;&gt;&lt;img src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh2uloJRj6KEjcZPz-OkgvqdIlXRRB4HvpuDQocU1x9k4IRo3kpNqjhB3IDMx4pV5qVZNwgRkGn2iS0QU0h4fVij3RmsSzZyetF4xZTlC-GakVrouuYLToCDBH56PLraBjyTLb53NhUgm0/s320/naja2.jpg&quot; border=&quot;0&quot; alt=&quot;&quot; id=&quot;BLOGGER_PHOTO_ID_5494366292401343346&quot; style=&quot;float: left; margin-top: 0px; margin-right: 10px; margin-bottom: 10px; margin-left: 0px; cursor: pointer; width: 320px; height: 246px; &quot; /&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;&lt;div&gt;&lt;span style=&quot;font-family:Arial;&quot;&gt;&lt;span class=&quot;Apple-style-span&quot;  style=&quot; color: rgb(0, 0, 238); -webkit-text-decorations-in-effect: underline; font-family:Georgia, serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;  &lt;p class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;&lt;span style=&quot;font-family:Arial;&quot;&gt;E por falar em nisso, outra confusão, embora popularmente costuma-se dividir as serpentes em venenosas e não venenosas, o termo correto é serpente peçonhenta e não peçonhenta...&lt;/span&gt;&lt;/p&gt;&lt;p class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;&lt;span style=&quot;font-family:Arial;&quot;&gt;...mas o que é isso?&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;  &lt;p class=&quot;MsoNormal&quot; style=&quot;text-align:justify&quot;&gt;&lt;span style=&quot;font-family:Arial;&quot;&gt;Serpentes peçonhentas são aquelas que produzem veneno e possuem presas (voltarei nesse assunto em breve) para injetá-lo, como as najas do exemplo, as jararacas, cascavéis e corais, para citar algumas das mais conhecidas.
