EtymologyBunocephalus: From the Greek bounos, meaning hill and kephale, meaning head; in reference to the bumps on the head of the fish, which is particularly marked in some species. Named in honor of Charles Frederick Hartt, a Canadian-American geologist, and first professor of Geology at Cornell University. Hartt worked extensively in Brazil and published "Geology and physical geography of Brazil." Hartt also served as the founder and director of the section of geology at the Museu Nacional of Brazil from 1866 to 1867.

Size 58mm or 2.3" SL. Find near, nearer or same sized spp.
IdentificationBunocephalus hartti is distinguished from all congeners by the absence of serrations along the anterior margin of the pectoral-fin spine in adults (vs. presence of serrations along the anterior margin in adults of all other Bunocephalus); feeble serrations are present along the anterior margin of the pectoral-fin spines of juveniles. B. hartti can be further distinguished from most congeners, except for B. verrucosus, by having the last dorsal-fin ray completely or almost completely attached to the dorsum (vs. dorsal-fin ray completely free or connected to the dorsum along less than half of its length in all other Bunocephalus).
General RemarksColor in alcohol: Head and body light brown dorsally, ventral portions lighter brown to yellowish pale. Four saddles of dark coloration on dorsal surface of body. First dark saddle at level of dorsal fin, second at anal fin vertical, third at middle caudal peduncle and fourth at origin of caudal fin. Second, third and fourth saddles sometimes not connected at middorsal line. Dorsal fin mostly dark brown with light distal margin; pectoral fin whitish cream to hyaline with small light brown spots, pelvic and anal fins mostly hyaline, without conspicuous dark spots. Caudal fin hyaline with dark blotch at proximal portion and scattered black spots on distal third sometimes forming band.
