Myliobatidae (Eagle and manta rays)
Etymology: Aetomylaeus: Greek, aetos = eagle + Greek, mylio = mill, grinder (Ref. 45335).
Environment: milieu / climate zone / Tiefenbereich / distribution range
Ökologie
seewasser; brackwasser benthopelagisch; tiefenbereich 10 - 150 m (Ref. 6808). Subtropical; 44°N - 35°S, 19°W - 36°E
Eastern Atlantic: Portugal and Morocco to Angola, including the Mediterranean, Madeira and the Canary Islands; then from Saldanha Bay to Natal (South Africa) and southern Mozambique (Ref. 5578).
Length at first maturity / Size / Gewicht / Alter
Geschlechtsreife: Lm 90.0, range 35 - 148 cm
Max length : 222.0 cm WD (female); common length : 150 cm WD Männchen/unbestimmt; (Ref. 57025); max. veröff. Gewicht: 116.0 kg (Ref. 85836)
Long, flat, rounded snout like a duck's bill; head thick and pectoral disc with sharply curved, angular corners; upper or lower jaw; usually with 7 rows of flat teeth (Ref. 5578). Light brown with several pale blue-grey stripes (may be absent) dorsally, white ventrally (Ref. 5578).
Body shape (shape guide): other.
Found in coastal tropical and warm temperate waters, occasionally offshore. Sometimes found in small groups (Ref. 5578). Feed on bottom-living crustaceans and mollusks. Ovoviviparous (Ref. 50449), aplacental (Ref. 57025). Prized angling fish, often released (Ref. 5578). Flesh highly esteemed (Ref. 3965).
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). Gestation about 6 months; 3-7 young produced (Ref. 5578). Size at birth 45 cm WD (Ref. 6677).
