Descrição breve
Chaves de identificação | Morfologia | Morfometria
This small mobulid is distinguished by the following characters: pectoral fins very short and with one of the lowest aspect ratios of the genus (i.e. the ratio of DW to disc length, 1:0.578, n = 50), with high relative values of longitudinal metrics (e.g. disc length and anterior projection); head and cephalic fins very elongated with tip of cephalic fin to spiracle 16.5% of DW (n = 50); pre-oral length 5.9% of DW (n = 50); no caudal spine; base of tail quadrangular in section; spiracle very small, subcircular, ventral to plane of pectoral fins; a distinct dark blotch on ventral side of pectoral fins at the midpoint along the leading edge; branchial filter plates distinctively reduced, with four (rarely five) lateral lobes; terminal lobe also distinctively elongated and leaf shaped, pointed terminal lobe (its length almost one-quarter of the plate); colour of plates whitish pink; tooth bands on average 73% of mouth width; most teeth in adult males with multiple long lingual cusps (Ref. 132274).
Cross section: oval.
Found in coastal and oceanic waters (Ref. 30573); solitary or aggregations, sometimes with 50 or more individuals (Ref. 90102). Not known to penetrate the epipelagic zone (Ref. 9911). Ovoviviparous (Ref. 50449).
Ciclo de vida e comportamento de acasalamento
Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas
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).
