Adults inhabit deep waters but rises to the surface at night. Rare species (Ref. 559). They live in tubes in fine sand or mud and rise to the surface at night where they fall prey to pelagic fishes (Ref. 37816). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).

Estimates based on models
Preferred temperature (Ref. 115969
): 2.4 - 6.8, mean 3.5 °C (based on 2061 cells).
Phylogenetic diversity index (Ref. 82805
= 0.7500 [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
Trophic level (Ref. 69278
): 4.2 ±0.73 se; based on food items.
Resilience (Ref. 120179
