जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

Found on shallow waters (<5 meters), in intertidal pools (Ref. 124789) with rocky substrate (Ref. 119717). Occur on both sheltered and exposed shores. Clustered in rock crevices, or at the base and undersides of boulders. Aggregation suggests adaptive behavior to wave turbulence (Ref. 127097). An opportunistic feeder, but feeds mainly on algae (Ref. 125532).

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

Members of the class Echinoidea are gonochoric. Fertilization is external. Brooding is common, eggs are held either on the peristome, around the periproct or deep into the concavities on the petaloids. Life cycle: Embryos develop into planktotrophic larvae (echinoplateus) and live for several months before they sink to the bottom using their tube feet to adhere on the ground where they metamorphose into young urchins.
