Biologie     Verklarende woordenlijst (bv. epibenthic)

Ranges from intertidal areas (where they may remain out of water under rocks or seaweeds, Ref. 31184) to deeper water over sand and mud bottoms (Ref. 4925). Adults make vertical migrations at night (Ref. 6885). Feed on crustaceans and fishes (Ref. 6885). Oviparous with eggs and larvae attached to nest wall (Ref. 36489). Nest is guarded by male (Ref. 36489). Important prey item for seals and sea lions (Ref. 2850). Adults breathe air when out of water (Ref. 31184). Possess photophores which are arranged on the underside of the head in a 'U' fashion.

Levenscyclus en paargedrag Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | Larven

Nests are cavities that are formed under rocks and eggs are deposited on the roof of the cavity. As few as 19 or as much as 789 eggs have been found attached in a nest. Eggs are guarded by the fasting male. Probably polygamous (Ref. 6885).
