Neritic, estuarine (Ref. 116114). Euryhaline medusae occurring in mixohaline and euhaline waters (3 to 5 parts per thousand). Feeds on polychaetes and comb jellies. Preyed upon by spider crabs, harvest fish and orange filefish. Acts as shelter for young harvest fish (Peprilus elepidotus). Venomous. Associated with Libinia dubia (Ref. 3095).
Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
Undergoes metagenesis, alternation between polyp and medusa generation. Sessile polyps reproduce asexually (i.e. podocyst formation). During spring and summer, undergoes strobilation to give rise to ephyrae, which rapidly grows into dioecious medusae. Hermaphroditism is known but rare. Eggs are shed into gastrovascular cavity. Fertilization takes place either in the cavity or externally and produces free-swimming planula larvae, which settles on firm substrate and eventually develop in polyps.
