Length at first maturity / Size / Weight / Age

Maturity: Lm 6.8  range ? - ? cm Max length : 25.4 cm SHL male/unsexed; (Ref. 95991); max. reported age: 17 years (Ref. 95991)

Biology     Glossary (e.g. epibenthic)

It burrows in sand and mud along the intertidal zone from shallow depths to 30 meters (Ref. 865). Prefers sandier areas. Buries deep in the substrate to avoid freezing (Ref. 95344). Feeds on phytoplankton and detritus (Ref. 95991).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Reproduction occurs throughout the year during spring, peak months on February and April.
