Known to occur on bathyal, infralittoral and circalittoral of the Gulf and estuary. Generally for group, planktonic and minute detrital food items through either suspension or deposit feeding (Ref. 87872).
Life cycle and mating behavior
بلوغ | تولید مثل | تخم ریزی | Eggs | Fecundity | Larvae
Sexes are separate but are seldom conspicuously different externally, simultaneous hermaphrodites yet self-fertilization is prevented due to various morphological, physiological, or behavioral mechanisms; generally, marine gastropods shed their eggs (Ref. 87872).
