Etymology: Hypselognathus: Greek, hypselos = high + Greek, gnathos = jaw (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 40 - 55 m (Ref. 5316). Subtropical
Eastern Indian Ocean: known only from the Great Australian Bight.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 15 - ? cm
Max length : 27.3 cm SL male/unsexed; (Ref. 5316)
Found on the continental shelf (Ref. 75154). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Probably brooding at 15.4 cm SL.
