जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

Adults inhabit passages and outer reef slopes, solitarily or in small groups. They are sometimes seen in mixed aggregations with the closely related species C. margaritifer (Ref. 7247). Feeds on planktons (Ref. 89972). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Diurnal species (Ref. 54980; 113699).
