Actinopterygii (ray-finned fishes) > Aulopiformes
(Grinners) > Notosudidae
Etymology: Ahliesaurus: Because of Dr. Ernest Ahli, born in Berlin, 1898 + Greek, sauros =lizard (Ref. 45335).
Environment / Climate / Range
Marine; bathypelagic; depth range 0 - 2000 m (Ref. 35509). Deep-water; 40°N - 40°S
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 26.9 cm SL male/unsexed; (Ref. 6552)
Tropical and subtropical Atlantic, southwestern Indian and central South Pacific oceans.
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).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00288 (0.00120 - 0.00695), b=3.18 (2.96 - 3.40), based on LWR estimates for this Family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.0 ±0.00 se; Based on food items.
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (Assuming semelparity and tm>5).
Vulnerability (Ref. 59153
): Low vulnerability (23 of 100) .
