Actinopteri (ray-finned fishes) > Aulopiformes
(Grinners) > Notosudidae
Etymology: Ahliesaurus: Because of Dr. Ernest Ahli, born in Berlin, 1898 + Greek, sauros =lizard (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range 0 - 2000 m (Ref. 35509). Deep-water; 40°N - 40°S
Tropical and subtropical Atlantic, southwestern Indian and central South Pacific oceans.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 26.9 cm SL male/unsexed; (Ref. 6552)
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 based on models
Preferred temperature (Ref. 115969
): 5.5 - 15, mean 9.1 °C (based on 1365 cells).
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00295 (0.00121 - 0.00721), b=3.18 (2.96 - 3.40), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.00 se; based on food items.
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Assuming semelparity and tm>5).
Vulnerability (Ref. 59153
): Low vulnerability (23 of 100) .
