Biologi     Daftar kata (contoh epibenthic)

Apparently associated with coral or sandstone reefs of the northeastern Brazilian continental shelf. Two female specimens were collected from the stomach of Rachycentron canadum (Ref. 36974). Juveniles also occurred in sandy beaches and estuaries. Ovoviviparous (Ref. 50449).

Siklus hidup dan perilaku kawin Kematangan | Reproduksi, perkembang biakan | Pemijahan | telur-telur | Fekunditas | Larva

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). Distinct pairing with embrace (Ref. 205). A gravid female aborted one fully formed embryo (Ref. 36974).
