|Cat-eLog Data Sheet|
|Scientific Name||Chaetostoma palmeri Regan, 1912|
|Type Locality||Río Tamana, Río San Juan system, Chocó Dept., southwestern Colombia.|
|Pronunciation||KATE oh STOW mah|
|Etymology||Greek, chaite = hair + Greek, stoma = mouth.|
|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.|
|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.|
|Distribution||South America: Tamana River basin in San Juan River drainage, Colombia.|
|Furniture||Well rounded stones stacked to replicate a river bottom and provide caves.|
|Breeding||Spawns in shallow, fast flowing water on the underneath of a flat object. Male, upside down, guards an adhesive clutch of eggs by, more or less, covering it with his body.|
|Breeding Reports||There is no breeding report.|
|References||Proceedings of the Zoological Society of London 1912 (pt 3), pp 667, Pl. 75 (fig. 3).|
