Barton Springs Salamander

The Barton Springs salamander (Eurycea sosorum) is a small lungless salamander unique to Barton Springs, a group of natural springs in Austin, Texas. Its speckled, reddish-brown skin is translucent and eggs or even the contents of the salamander’s last meal are often visible.

Since the Barton Springs salamander is found nowhere else in the world and relies on fresh, unpolluted spring water it’s been listed as an endangered species since 1997.

The Antarctic Photographs of Herbert Ponting

The British Antarctic (Terra Nova) Expedition, 1910-1913, on which Captain Robert Falcon Scott and four of his companions perished whilst returning from the South Pole, is among the most important early expeditions to the Antarctic. The photographs of the endeavour taken by Herbert Ponting, constitute one of the most compelling visual records in the history of exploration. [via]

The Amiskwia (1911)

Phylum : Incertae sedis
Genus : Amiskwia
Species : A. sagittiformis

Middle Cambrian (505 Ma)

3 cm long (size)

Canada (map)

Amiskwia is a genus of large, soft-bodied invertebrate of unknown affinity known from fossils of the Middle Cambrian Lagerstätten both in the Burgess shale formation in British Columbia and the Maotianshan shales of Yunnan Province, China.

Very few specimens of this organism have been found, only eighteen of the Burgess shale species, A. sagittiformis, and a single specimen of the Maotianshan species, A. sinica — which may be a reflection of its genuine rarity, but is more likely to be due to taphonomic (preservational) or behavioural factors.

The fossils reach 25 mm in length. The head is rounded, tipped with two tentacles, and appears to contain a four-ganglion brain; the body flattens out and broadens in the trunk, which appears to have been fairly muscular. Where the trunk meets the head there is a small tubular opening, which can be interpreted as the mouth; the gut terminates where the trunk narrows and meets the tail, which is broad and paddle shaped. The body morphology suggests a free energetic swimmer, which may be consistent with the dearth of fossils…
