Biologie     Glossaire (ex. epibenthic)

Benthic (Ref. 58302). Adults occur from lowland streams and rivers to relatively swift streams at elevations of 1000 m. They often burrow into the substrate with only the eyes showing; feed on filamentous algae, worms, crustaceans, various insects and insects larvae, and suspended food particles; has been long favored as food by the early Hawaiians (Ref. 44091). Larvae develop and metamorphose in the marine zooplankton and as juveniles, about 161 days old, recruit to freshwater streams, where they undergo rapid growth and morphological changes necessary for upstream migration to the adult habitat (Ref. 51037).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Adults move downstream to their prime breeding just above the estuary; males select crevices and caves formed by rocks on the stream bed where the females will lay their eggs; males guard nests until larvae hatch a day later (Ref. 44091).
