Chaetostoma sp. (L348) • Loricariidae • Cat-eLog

Cat-eLog Data Sheet
Scientific Name	Chaetostoma sp. (L348)
Common Name(s)	L348
Pronunciation	KATE oh STOW mah
Etymology	Greek, chaite = hair + Greek, stoma = mouth
Species Information
Size	240mm (9.4") SL. Find near, nearer or same sized spp.
Identification	The genus Chaetostoma is not straight-forward 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. Similar to the Colombian C. milesi, but grows much larger. The spots on the head are much smaller than in C. milesi.
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.
