Species Information | |
Size | 95mm or 3.7" SL. Find near, nearer or same sized spp. |
Identification | The genus Chaetostoma is not straightforward to identify, but as a general rule, the species has spines behind the gill-cover (interopercular odontodes), no plates on the abdomen, and aside from C. platyrhynchus also lack plates on the snout edge. Different from Ancistrus by not having fleshy tentacles on the snout. Holotype: Color in alcohol dull olive-brown, under surface paler or light grayish. Dorsal with membranes grayish. Caudal brownish and with 4 dark parallel gray-brown transverse bands, though all inclined and parallel with hind caudal edge. Paired fins brown, with indistinct and obscure brown spots on rays. Iris gray. Paratypes: Most uniform brown. Some vary with obscure markings, an occasional specimen with 3 obscure transverse darker bands on the caudal or a submarginal diffuse dark grayish band, and in addition sometimes a faint gray blotch below middle of each ray. |
Sexing | The males have however a larger and broader head, slimmer ventral sides and disproportionately large pelvic fins. Perhaps the over-sized pelvic fins play a large role in the fertilization of the eggs. By inverting these over the clutch of eggs, they prevent the sperm cells being carried away by fast water current. |
