Eponymy: Henry von Prahl (1948–1989) was a pioneering Colombian marine biologist who studied Gorgona Island (the type locality) and whose family emigrated from Germany (1953). He was killed by a bomb, which exploded on Avianca Airlines Flight 203 over Bogotá. (Ref. 128868), visit book page.

Body shape (shape guide): elongated.
Living individuals reported to be in sandy and rocky environments near coral-reefs at 18-24 m depth of the Colombian coast (Ref. 101827). In contrast the type specimen was taken from a depth of 70 m (Ref. 26282). Ovoviviparous (Ref. 50449). Males mature at ca. 71 cm TL (Ref. 114953).
Siklus hidup dan perilaku kawin Kematangan | Reproduksi, perkembang biakan | Pemijahan | telur-telur | Fekunditas | Larva
Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449).
