Mongoose (Herpestidae) are a family of 33 living species of small carnivorans from southern Eurasia and mainland Africa. Four additional species from Madagascar in the subfamily Galidiinae, which were previously classified in this family, are also referred to as "mongooses" or "mongoose-like". Genetic evidence indicates that the Galidiinae are more closely related to other Madagascar carnivorans in the family Eupleridae, which is the closest living group to the true mongooses.
Name
The word mongoose is derived from the Marathi name mangus (मंगूस) (pronounced as [məŋɡuːs]), perhaps ultimately from Dravidian (cf. Telugu mungeesa (ముంగిస), Kannada mungisi (ಮುಂಗಿಸಿ). The form of the English name (since 1698) was altered to its -goose ending by folk-etymology. It has no etymological connection with the word goose. The plural form is mongooses, or, rarely, mongeese. It has also been spelled mungoose.
Mongooses bear a striking resemblance to mustelids, having long faces and bodies, small rounded ears, short legs, and long tapering tails. Most are brindled or grizzly; few have strongly marked coats. They have non-retractile claws that are used primarily for digging. Mongooses, much like goats, have narrow, ovular pupils. Most species have a large anal scent gland, used for territorial marking and signaling reproductive status. The dental formula of mongooses is similar to that of viverrids:. Mongooses also have receptors for acetylcholine that, like the receptors in snakes, are shaped so that it is impossible for snake neurotoxin venom to attach to them. Researchers are investigating whether similar mechanisms protect the mongoose from hemotoxic snake venoms.

most dangerous caterpillar

noreply@blogger.com (Unknown) — Sat, 3 Sep 2011 21:14:00 -0700

Caterpillars are the larval form of a member of the order Lepidoptera (the insect order comprising butterflies and moths). They are mostly herbivorous in food habit, with some species being insectivorous. Caterpillars are voracious feeders and many of them are considered pests in agriculture. Many moth species are better known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce.

The etymological origins of the word are from the early 16th century, from Middle English catirpel, catirpeller, probably an alteration of Old North French catepelose: cate, cat (from Latin cattus) + pelose, hairy (from Latin pilōsus).[
Most caterpillars have tubular, segmented bodies. They have three pairs of true legs on the three thoracic segments, up to four pairs of prolegs on the middle segments of the abdomen, and often a single pair of prolegs on the last abdominal segment. There are ten abdominal segments. The families of lepidoptera differ in the numbers and positioning of the prolegs. Some caterpillars are fuzzy (which means they have hair), and they are most likely to cause itching of the hands if touched.

Caterpillars grow through a series of moults; each intermediate stage is called an instar. The last moult takes them into the inactive pupal or chrysalis stage.

Like all insects, caterpillars breathe through a series of small openings along the sides of their thorax and abdomen called spiracles. These branch into the body cavity into a network of tracheae. A few caterpillars of the family Pyralidae are aquatic and have gills that let them breathe underwater.

Caterpillars have about 4,000 muscles (compared to humans, with 629). The average caterpillar has 248 muscles in the head segment alone.

Caterpillars move by sliding their internal organs forward using contraction of the muscles; the torso first elongates and then contracts like a slinky. They are one of the only known organisms that use this method of locomotion. Another way of describing this process is: gut-first, body-later.
Caterpillars do not have good vision. They have a series of six tiny eyelets or 'stemmata' on each side of the lower portion of their head. These can probably form well focused, but poorly resolved images. They move their heads from side to side probably as a means of judging distance of objects, particularly plants. They rely on their short antennae to help them locate food.

Some caterpillars are able to detect vibrations, usually at a specific frequency. Caterpillars of the common hook-tip moth, Drepana arcuata (Drepanoidea) produce sounds to defend their silk nests from members of their own species, by scraping against the leaf in a ritualized acoustic duel. They detect the vibrations conducted by the plant and not airborne sounds. Similarly, cherry leaf rollers Caloptilia serotinella defend their rolls. Tent caterpillars can also detect vibrations at the frequency of wing beats of one of their natural enemies
Classification
The geometrids, also known as inchworms or loopers, are so named because of the way they move, appearing to measure the earth (the word geometrid means earth-measurer in Greek); the primary reason for this unusual locomotion is the elimination of nearly all the prolegs except the clasper on the terminal segment.

Caterpillars have soft bodies that can grow rapidly between moults. Only the head capsule is hardened. In caterpillars, the mandibles are tough and sharp for chewing leaves; in most adult Lepidoptera, the mandibles are highly reduced, or soft. Behind the mandibles of the caterpillar are the spinnerets, for manipulating silk.

Some larvae of the Hymenoptera (ants, bees and wasps) order can appear like the caterpillars of the lepidoptera. These are mainly seen in the Sawfly family and while the larvae superficially resemble caterpillars, they can be distinguished by the presence of prolegs on every abdominal segment. Another difference is that lepidopteran caterpillars have crochets or hooks on the prolegs while these are absent on the sawfly larvae. Also in lepidopteran caterpillars is the upside down Y shaped suture on the front of the head. The larvae of sawflies differ also in having prominent ocelli on the head capsule.

Most famous cattle dog

noreply@blogger.com (Unknown) — Sat, 3 Sep 2011 21:04:00 -0700

The Australian Cattle Dog (ACD) is a breed of herding dog originally developed in Australia for droving cattle over long distances across rough terrain. Today it is a versatile breed: a courageous and tireless worker, an intelligent and athletic companion and a loving and playful family pet. They can bite "if harshly treated", they tend to nip heels to herd people, and they can be aggressive with other dogs. However, they are loyal and biddable, and respond well to training.

The Australian Cattle Dog is a medium-sized, short-coated dog that occurs in two main colour forms. The dogs have either brown or black hair distributed fairly evenly through a white coat, which gives the appearance of red or blue dogs. They have been nicknamed “Red Heelers” and “Blue Heelers” on the basis of this colouring and their practice of moving reluctant cattle by nipping at their heels. Dogs from a line bred in Queensland, Australia, which were successful at shows and at stud in the 1940s were called “Queensland Heelers” to differentiate them from lines bred in New South Wales, and this nickname is now occasionally applied to any Australian Cattle Dog.

While there is a good deal of mythology surrounding the origins of breed, in recent years, information technology that enables the manipulation of large databases, and advances in the understanding of canine genetics has allowed a clearer understanding of the Halls Heeler, its dispersal through eastern Australia, and its development into two modern breeds: the Australian Cattle Dog and the Australian Stumpy Tail Cattle Dog.

As with dogs from other working breeds, Australian Cattle Dogs have a good deal of energy, a quick intelligence, and an independent streak They respond well to structured training. They are not aggressive, but form a strong attachment with their owner and can be very protective of them and their possessions. They are easy to groom and maintain. The most common health problems are deafness and progressive blindness (both hereditary conditions) and accidental injury; otherwise, they are a robust breed with a lifespan of 12 to 14 years. Australian Cattle Dogs participate in a range of activities, from obedience, agility and herding competitions, to participating with their owners in hiking, flying disc, and endurance events, and working as therapy, assistance, or police dogs.Australian Cattle Dogs are sturdy, compact dogs that give the impression of agility and strength. They have a broad skull that flattens to a definite stop between the eyes, with muscular cheeks and a medium-length, deep, powerful muzzle. The ears are pricked, small to medium in size and set wide apart, with a covering of hair on the inside. The eyes are oval and dark, with an alert, keen expression. The neck and shoulders are strong and muscular; the forelegs are straight and parallel; and the feet round and strongly arched, with small toes and strong nails.

They should have well-conditioned muscles, even when bred for companion or show purposes. Ideally, their appearance is symmetrical and balanced, with no individual part of the dog being exaggerated. They should not look either delicate or cumbersome, as either characteristic limits the agility and endurance that is necessary for a working dog.

[edit] Size
Female Australian Cattle Dogs measure approximately 43–48 centimetres (17–19 in) at the withers, and males measure about 46–51 centimetres (18–20 in) at the withers. The dog should be longer than tall, that is, the length of the body from breast bone to buttocks is greater than the height at the withers, in a ratio of 10 to 9.[8] Australian Cattle Dogs in good condition weigh approximately 20–28 kilograms (44–62 lb).

The Pacific Gopher Snake (Pituophis catenifer catenifer) is a species of large colubrid snake native to the western coast of the United States.
Description
The Pacific Gopher Snake adults range in size from 2.5-7 feet (76-213 cm). However, most of the subspecies reach a length of 4.5-5 feet (137-152 cm). The hatchlings are relatively long, and they have been recorded at lengths upward of 20 inches (51cm).

The Pacific Gopher Snake has a base color ranging from yellow to dark brown and has a grey coloring on the sides of the body. It is a spotted snake, with the spots being dark brown. Usually there are 41 to 99 spots on the body, while the tail spots range from 14 to 33 spots. The side of the body shows 2 or 3 rows of alternating rows of black and brown spots.

A snake with keeled scales, and a narrow head that is wider than the neck, the Pacific Gopher Snake also displays a protruding rostral scale on the tip of the snout. The two most common base colors are straw and straw grey, though the species' color varies widely. The dorsal blotches, or saddles, are well-defined and generally dark to chocolate brown, though some specimens have had black blotches. The side blotches are often brown or grey. The back of the neck is dark brown. In many areas, such as Solano County, California, the snake can be found in a striped morph.

The ventral side may be cream-colored to yellowish with dark spots. On the dorsal side, especially near the tail, there is often a reddish coloration.
Identification
As aforementioned, there are 2 to 3 rows of spots on the side of the Pacific Gopher Snake. However, the San Diego Gopher Snake (P. c. annectens) has 3 to 4 rows of smaller spots on their sides. The Pacific Gopher Snake's saddle spots do not have the barren characteristic as the San Diego Gopher Snakes do. Also, the second row of spots are much larger on P.c. catenifer compared to P.c. annectens. Finally, the Pacific Gopher Snake generally has more saddle spots than the San Diego Gopher Snake.
Behavior
The snake is diurnal, though sometimes active at dusk and nocturnal during warm weather. They prefer drier habitats such as meadows, fields and agricultural farmland, and are seldom found in dense forests.

Like other gopher snakes, the Pacific gopher can produce a loud hiss when agitated or fearful. When threatened, this species will inflate its body, flatten its head, and vigorously shake its tail, which may produce a rattling sound if done in dry vegetation. However, Gopher snakes are generally good natured.

The Pacific Gopher Snake is a carnivore. Their diet consists of small mammals, notably pocket gophers; birds and their eggs; the occasional lizard and insect,and even bats. It is reputed to sometimes consume rattlesnakes.

Venomous snakes are snakes which have venom glands and specialized teeth for the injection of venom. Members of the families Elapidae, Viperidae, Hydrophiidae, and Atractaspididae (and some from Colubridae as well) are major venomous snakes.
Description
Venomous snakes use modified saliva, snake venom, usually delivered through highly specialized teeth such as hollow fangs, for the purpose of prey immobilization and self-defense. In contrast, non-venomous species either constrict their prey, or simply overpower it with their jaws.

Venomous snakes include several families of snakes and do not form a single taxonomic group. This has been interpreted to mean that venom in snakes originated more than once as the result of convergent evolution. Evidence has recently been presented for the Toxicofera hypothesis however; venom was present (in small amounts) in the ancestor of all snakes (as well as several lizard families) as 'toxic saliva' and evolved to extremes in those snake families normally classified as venomous by parallel evolution. The Toxicofera hypothesis further implies that 'non venomous' snake lineages have either lost the ability to produce venom (but may still have lingering venom pseudogenes), or actually do produce venom in small quantities, likely sufficient to assist in small prey capture, but cause no harm to humans if bitten.

Lists or rankings of the world's "most venomous snakes" are tentative and differ greatly due to numerous factors, including the recentness and reliability of the data, the number of species analyzed, and the testing methods used.[1] In addition, since mice are the common indicator used to test venom from venomous snakes in LD50 tests, the LD50 results may not reflect the actual effects on humans due to the physiological differences between mice and humans. For example, many venomous snakes are specialized predators on mice, and their venom may be adapted specifically to incapacitate mice. While most mammals have a very similar physiology, LD50 results may or may not be directly relevant to humans.

venomous snakes eat the frog
venomous snakes dangerous
venomous snakesWhile there have been numerous studies on snake venom, potency estimates can vary, creating overlap and greatly complicating the task. Further, LD50 may be measured through intramuscular, intraperitoneal, intravenous or subcutaneous injections on small rodents, although the latter is the most applicable to actual bites It should also be considered that mice, the most commonly used animals in determining LD50, may react to some snake venoms differently than humans do. Thus, it remains difficult to compile such lists.

Many of these lists only take into account of terrestrial and arboreal snakes and neglect to list the of venom of the sea snakes. Species of sea snakes have been listed to have more toxic venom than even that of the inland taipan and further investigations of some species' venom are needed

Other information
Venomous snakes are often said to be poisonous, although this is not the correct term, as venoms and poisons are different. Poisons can be absorbed by the body, such as through the skin or digestive system, while venoms must first be introduced directly into tissues or the blood stream (envenomated) through mechanical means. It is, for example, therefore harmless to drink snake venom as long as there are no lacerations inside the mouth or digestive tract. There are however two exceptions: the Rhabdophis snakes (keelback snakes) secrete poison from glands that it gets from the poisonous toads that it preys on; similarly certain garter snakes from Oregon retain toxins in their liver from the newts they eat.
