Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 16.5 cm SHL male/unsexed; (Ref. 109255)
The shell lacks radiating ridges containing three small teeth below the beak. The exterior is often bluish black with the interior portion being dull blue (Ref. 310).
Found in warmer waters (Ref. 95344). Occurs in quiet waters and lives lower in the intertidal zone attached to rock substrates (Refs. 310, 125090). Inhabits muddy and sandy bottoms (Ref. 125090). Smaller individuals move to the outer edge of the colony (Ref. 310). Feeds on a variety of phyto- and zooplankton (Ref. 112108).
Life cycle and mating behavior
