生物学特性     字汇 (例如 epibenthic)

Uncommon species (Ref. 34024). Benthic (Ref. 58302). Adults inhabit the body cavity of pearl shells (Pinctada), pen shells (Pinna), and cockles (Laevicardium). Oviparous, with pelagic vexillifer stage larva, and benthic tenuis stage larva (Ref. 36487). Also found in following shells in the Gulf of California: Megapitaria squalida, M. aurantiaca, Laevicardium elatum and Spondylus princeps (Ref. 38407).

Estimates based on models

Preferred temperature (Ref. 123201): 19.7 - 28.9, mean 26 °C (based on 72 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.5   ±0.5 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
