Eurycea waterlooensis Hillis, Chamberlain, Wilcox & Chippindale 2001

Description ( Inglês )

fornecido por AmphibiaWeb articles
This species is a perennibranchiate form that maintains permanent larval morphology. E. waterlooensis has a mixture of morphological characters which set it apart from the rest of Eurycea. These include: the absence of external eyes - no image-forming lenses but instead small subdermal eye spots; its characterization as a perennibranchiate; the presence of 12 costal grooves; limbs proportionately smaller than in its two closest relatives - E. rathbuni and E. robusta; and weakly developed tail fins - the ventral section of the tail fin is present only on the posterior half and the dorsal section is nearly absent on the anterior half. This species has an extended snout and a shimmering, lustrous white appearance due to the reflective connective tissue that lies beneath its transparent skin. Occasionally, shades of lavender are exhibited, and a row of iridophores sometimes can be found along the sides of body and tail.

Distribution and Habitat ( Inglês )

fornecido por AmphibiaWeb articles
E. waterlooensis has an extremely limited distribution. It has been discovered in three of the four outlets of Barton Springs in Austin, Texas. The species is thought to be restricted to the subterranean cavities of the Edwards Aquifer, and so the individuals found at the outlets are believed to to have been flushed out of the aquifer accidentally.

Life History, Abundance, Activity, and Special Behaviors ( Inglês )

fornecido por AmphibiaWeb articles
Diet includes at least ostracods, copepods, amphipods, and aquatic plants. In captivity, it readily eats a variety of small invertebrates. Captive individuals also enjoy crawling out of water and adhering to the wet glass of the aquarium walls with their flattened tails. They spend many minutes at a time out of water if humidity nears 100%.

Life History, Abundance, Activity, and Special Behaviors ( Inglês )

fornecido por AmphibiaWeb articles
E. waterlooensis has recently been included in the City of Austin's captive breeding program along with the endangered E. sosorum. Human disturbances at Barton Springs are likely to have less impact on the subterranean E. waterlooensis than surficial E. sosorum, but it has still been negatively affected by development and increasing siltation.

Relation to Humans ( Inglês )

fornecido por AmphibiaWeb articles
This is a salamander that has been discovered in a highly urban area. Its discovery in the same place as the discovery of an earlier species has alerted the local citizens and led to substantial discussion concerning biodiversity preservation and habitat conservation.

Austin blind salamander ( Inglês )

fornecido por wikipedia EN

The Austin blind salamander (Eurycea waterlooensis) is an endangered species of salamander in the family Plethodontidae, endemic to Barton Springs in Austin, Texas, United States.[1][6] Its name is derived from Waterloo, the original name of Austin.

Austin blind salamanders, typically juveniles, have been observed at spring outlets. However, probably most of the population lives in subterranean cavities, and its total abundance is unknown, but it seems much less abundant than the sympatric Barton Springs salamander (E. sosorum).[1]

It is a totally aquatic species that is paedomorphic (does not metamorphose).[1]
