Etymology: Lasiognathus: Greek, 'lasios' = hairy or wooly + Greek, 'gnathos' = jaw (with reference to the huge number of long teeth of the upper jaw) ( Ref. 86949).
Eponymy: Dr Charles William Beebe (1877–1962) was an American naturalist, ornithologist, marine biologist, entomologist, explorer and author. [...] (Ref. 128868), visit book page.

Size / Gewicht / Alter
Maturity: Lm ? range ? - ? cm
Max length : 11.5 cm TL (female)
Rückenflossenweichstrahlen (insgesamt) : 6 - 7; Afterflossenweichstrahlen: 4 - 5. Escal bulb without membranous anterior crest. Distal escal appendage compressed, transversely fan-shaped, bearing three bony escal hooks along posterior margin, without elongate prolongation emerging from bases of escal hooks. Posterior escal appendage cylindrical, tapering to a point (Ref 27827). Length of illicium 43-44%SL in small specimens, 47-50%SL in large specimens (8 to 11.2 cm); posterior escal appendage 0.5-2.5%SL, emerging from below escal pore; thin edge of distal appendage behind and between bases of escal hooks more or less folded; length of distal appendage, measured from surface of escal bulb to bases of escal hooks, 1.3-2.8% SL (Ref. 86949).
A piscivore, feeding occasionally on invertebrates (Ref. 27828).
