Issue
This species is considered as a junior synonym of Mobula mobular according to Last et al., 2016 (Ref. 114953) and White et al., 2017 (Ref. 115945:13). The species page will be removed,.

Environment: milieu / climate zone / depth range / distribution range Ecologia

marinhas associadas(os) a recifes; intervalo de profundidade 0 - 647 m (Ref. 106604), usually 0 - 200 m (Ref. 89423). Subtropical; 40°N - 30°S

Indo-Pacific: off South Africa, the Arabian Sea eastward to the Hawaiian Islands and Polynesia. Eastern Pacific: on the continental coast. Eastern Atlantic: Côte d'Ivoire but may probably be more wide-ranging. This has to be critically compared with Mobula mobular of the Mediterranean Sea and nominally elsewhere in the North Atlantic.

Descrição suscinta Chaves de identificação | Morfologia | Morfometria

Dark blue to black above, white below. Inner surface of cephalic fins silver grey with black tip, outer surface and side behind eye white (Ref. 11228). Shared characters between M. rancureli and Mobula japanica: teeth, placoid scales, and branchial filter morphologies, morphometrics, presence of tail spine, distinctive shape and coloration of dorsal fin, and general shape of body and coloration (Ref. 50641).

Found inshore, possibly in oceanic waters (Ref. 9911). Pelagic (Ref. 58302). Occurs singly or in groups (Ref. 9911). Feeds mainly on euphausiids (mainly Nictiphanes simplex), and to a lesser extent on copepods and crustacean larvae. May also feed on small fishes. Ovoviviparous (Ref. 50449). Acoustic tracks record the species to spend time above the thermocline at night to feed on krill (H. Dewar, pers.comm. 05/2000). Very common by-catch of the gillnet fisheries targeting skpjack tuna (Katsuwonus pelamis). Utilized for its gill filter plates (very high value), meat, cartilage and skin (Ref.58048).

Ciclo de vida ou comportamento de acasalamento Maturities | Reprodução | Spawnings | Egg(s) | Fecundities | 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). With one in a litter (Ref. 12951). Size at birth 85-92 cm WD (Ref. 12951, Ref.58048).

Estimates based on models

Preferred temperature (Ref. 123201): 17.5 - 29, mean 27.4 °C (based on 5840 cells).

Índice de diversidade filogenética (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.4 ±0.43 se; based on food items.

Generation time: 9.2 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
