Etymology: Ahliesaurus: Because of Dr. Ernest Ahli, born in Berlin, 1898 + Greek, sauros =lizard (Ref. 45335).
Eponymy: Dr Christoph Gustav Ernst Ahl (1898–1945) was an ichthyologist, herpetologist and aquarist. [...] Frederick Henry Berry (1927–2001) was an American systematic ichthyologist. [...] (Ref. 128868), visit book page.

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 10 - 11; Spine anali: 0; Raggi anali molli: 19 - 21. Olive brown in color, edges of scale pockets blackish; 2 black bands formed by peritoneum showing through body wall; blackish triangular spot on caudal base (Ref. 6602).
Body shape (shape guide): elongated.
Mesopelagic to bathypelagic (Ref. 6602). Sometimes taken at depths greater than 500 m (Ref. 6602). Feeds on smaller plankton, mainly copepods. Hermaphrodite, spawning probably occurs in the North Atlantic in a belt stretching across the ocean in subtropical latitudes. Specimens approaching sexual maturity lose their teeth and gillrakers completely (Ref. 6689) suggesting semelparity (RF).
