Allotoca goslinei, commonly known as the banded allotoca or tiro rayado in Spanish, is a species of fish in the family
Its
Morphology
On average, males are 31.9mm long and females are 33.6mm long. It has two rows of conical teeth. A. goslinei differs from others in Allotoca by the number of vertebrae, supraorbital pores, and number of vertical stripes on its side.[3]
Habitat
A. goslinei inhabited small pools that feed into the Ameca River, preferring to reside in still, shallow waters beneath algae and floating plants.[3]
Diet
Their diet likely consists of small arthropods.[2]
Sexual dimorphism
This species is sexually dimorphic in coloring and fin length. Notably males have a longer dorsal fin than females.[3]
Conservation
With only one known population located in a single tributary of the Ameca River, A. goslinei is an evolutionarily significant unit.[5] Though this species was first discovered in 1987,[3] pollution led to population decline by the 1990s and by the 2000s, a more rapid decline took place after the introduction of Xiphophorus helleri.[2][5]
Extinction
This species is now considered extinct in the wild, with the last known wild individuals were observed in 2004. No wild populations or individuals were found in surveys from 2005 and later. Small captive populations exist in Mexico, the United States, and Europe.[5]
