Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Circumglobal: In tropical to temperate waters. Adults (expatriates ?) found in boreal and subarctic waters. South China Sea and East China Sea (Ref.74511).

Biology     Glossary (e.g. epibenthic)

Maximum size observed for free living males is 1.3 cm (Ref. 10524). Males are parasitic, females oviparous with planktonic larvae (Ref. 36494). Eggs are presumably contained in floating gelatinous rafts (Ref. 36494).
