deskripsi pendek Morfologi | Morfometrik

Duri punggung (Keseluruhan (total)): 0; duri punggung lunak (Keseluruhan (total)): 0; Duri dubur 0; Sirip dubur lunak: 0. This species differs from all its congeners except E. caribbeaus, E. goliath, E. menezesi and E. strahani by having 7 pairs of gill pouches and three-cusp multicusps on the anterior and posterior rows of cusps. It differs from E. caribbeaus in number of anterior unicusps (8-11 vs. 11-13), posterior unicusps (7-9 vs. 10-11), total cusps (43-51 vs. 54-58) and prebranchial pores (16-20 vs. 13-15); from E. goliath in number of anterior unicusps (8-11 vs. 11-13), total cusps (43-51 vs. 54) and trunk pores (46-53 vs. 57-58); from E. menezesi in number of posterior unicusps (7-9 vs. 9-12), total cusps (43-51 vs. 52-60), tail pores (10-14 vs. 14-18); from E. strahani by its number of prebranchial pores (16-20 vs. 13-16) (Ref. 85052).

Biologi     Daftar kata (contoh epibenthic)

Occurs on soft bottoms of the continental slope (Ref. 7300). Able to form locally abundant populations and is often associated with inshore reefs (Ref. 85052).

Life cycle and mating behavior Kematangan | Reproduksi, perkembang biakan | Pemijahan | telur-telur | Fecundity | Larva

Copulatory organ absent. The gonads of hagfishes are situated in the peritoneal cavity. The ovary is found in the anterior portion of the gonad, and the testis is found in the posterior part. The animal becomes female if the cranial part of the gonad develops or male if the caudal part undergoes differentiation. If none develops, then the animal becomes sterile. If both anterior and posterior parts develop, then the animal becomes a functional hermaphrodite. However, hermaphroditism being characterised as functional needs to be validated by more reproduction studies (Ref. 51361 ).
