Distribution

The Blonde ray lives in the Eastern Atlantic Ocean, at depths of 10-380 m. It is found occasionally in the Mediterranean Sea as well. [5]

Description

Like all rays, the blonde ray has a flattened body with broad, wing-like pectoral fins. The body is kite-shaped with a short tail (hence the specific name brachyura, from Ancient Greek words meaning "short tail").

Maximum length is 120 cm (47 in).[6]

Life cycle

Oviparous, with embryos feeding only on yolk. The females lay about 30 egg-cases between February and November, using shallower coastal waters as nursing-grounds.[7]

Human use

Blonde rays are currently fished for human consumption, with a record weight of 37 lb (17 kg) recorded in Cobh, Ireland in 2008.[8][9]
