जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

Common in the sublittoral fringe around protected rocky coastlines (Ref. 102838). Found on muddy substrate (Ref. 2931). Occurs in assemblages in reef areas with high percentage of dead corals (Ref. 800). Common on Porites-dominated coral reefs; less common on Acropora assemblage (Ref. 102838). Feeds on algae (Also Ref. 128613) that grows on dead corals or rubble area (Ref. 800). Dwells in rocky and sandy substrates at depths of 1-70m. Also inhabits coral reefs and sea grass meadows. Hides in rocky crevices particularly when under intense light. Recorded from subsurface water temperatures of 16.9-30.8°C, oxygen concentration of 7.5 mg/L, and salinities of 36.4-38.7 per mille (Ref. 128613). Associated with coral communities. Dwells on soft substrates. Grazes on encrusting algae over hard substrates at night. Bioeroder. Keeps algal growth in check (Ref. 129602).

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.
