जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

It has a shell length of 7 cm long (Ref. 312). Occurs at low intertidal zones. Omnivorous; encrusting bryozoans are sometimes consumed in preference to algae. When under attack by a sea star, it will extend its mantle flap over its foot and shell so that the tube feet of the star fish cannot grasp it (Ref. 312).

Life cycle and mating behavior परिपक्व अवधि | पुनरुत्पत्ति | मछलीऔ का अंडे देना | Eggs | Fecundity | Larvae

Members of the order Patellogastropoda are mostly gonochoric and broadcast spawners. Life cycle: Embryos develop into planktonic trocophore larvae and later into juvenile veligers before becoming fully grown adults.
