Hartt worked extensively in Brazil, and a few of his notable accomplishments include the publication of 'Geology and physical geography of Brazil' (Hartt, 1870), and serving as the founder and director of the section of geology at the Museu Nacional of Brazil from 1866 to 1867.

Μαλακές ραχιαίες ακτίνες (συνολικά) : 5 - 6; Μαλακές εδρικές ακτίνες: 7 - 9; Σπόνδυλοι: 35. Bunocephalus hartti is distinguished from other species of Bunocephalus by the absence of serrations along the anterior margin of the pectoral-fin spine in adults (vs. presence). It further differs from most congeners, except for B. verrucosus, by having the last dorsal-fin ray completely or almost completely adnate to the dorsum (vs. dorsal-fin ray completely free or with less than half extension connected to the dorsum) (Ref. 104710).
Body shape (shape guide): elongated.
Facultative air-breathing in the genus
