Scientific Name Chaetostoma sp. (L336)   
Common Name L336
Pronunciation KATE oh STOW mah
Etymology Greek, chaite = hair + Greek, stoma = mouth. 
Down arrow Species Information
Size 80mm or 3.1" 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.
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.
