Actinopteri (ray-finned fishes) > Perciformes/Uranoscopoidei
(Sand dwellers) > Ammodytidae
Etymology: Ammodytoides: Greek, ammos = sand + Greek, dytes = anyone that likes immersions, diving (Ref. 45335); pylei: Named for Richard Pyle. More on authors: Randall, Ida & Earle.
Environment: milieu / climate zone / depth range / distribution range
Marine; benthopelagic; depth range 7 - 120 m (Ref. 10672). Tropical; 24°N - 18°N, 161°W - 151°W (Ref. 57359)
Eastern Central Pacific: Molakai to the Ladd Seamount, Hawaii.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 17.3 cm SL male/unsexed; (Ref. 10672); 14.2 cm SL (female)
Loose aggregation feeds on zooplankton as much as 5 meters above the sandy bottom. Highly protrusible premaxilla facilitates feeding on small animals of the zooplankton (Ref. 10672).

Estimates based on models
Preferred temperature (Ref. 115969
): 15.6 - 25, mean 20.3 °C (based on 2 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00339 (0.00154 - 0.00746), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.45 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (29 of 100) .
