The ocellated eagle ray has a wide and pointed disc shape, with one side being acutely pointed. Its head is round in cross-section and has a noticeable rostral lobe. The tail's length ranges from equal to the disc to three times longer, and it bears 1-5 venomous spines behind the dorsal fin. The upper surface is dark gray or greenish-gray with white spots or rings, while the underside is white.
Habitat and Biology
The ocellated eagle ray is a semipelagic species primarily inhabiting coastal waters, often seen near sandy bottoms, seagrass beds, and coral areas, although it can also venture offshore. It can be found at depths of at least 80 metres. This ray is usually seen alone, in pairs, or in groups. Its diet mainly comprises molluscs, but it also consumes crustaceans and worms. The ray is ovoviviparous, meaning it gives birth to live young after the eggs hatch internally. Each litter typically consists of two to four pups.
ECO System Qatar
Coral reefs are colonies of tiny animals thriving in nutrient-poor marine waters, typically in shallow, productive regions on solid substrates. Composed of calcium carbonate secretions, they serve essential ecological, economic, recreational, and cultural roles. They offer shelter and sustenance to various marine life, protect coastlines from storms and erosion, support fishing and leisure activities, and are part of cultural heritage. Around 10% of Qatar's seabed is covered by coral reefs, vital to over 80% of the Gulf's fish species. Noteworthy Qatar reefs are near Halul Island, Othman Reef, and Khor Al Udaid. Unfortunately, these reefs are endangered, as evidenced by a significant decline in coral health.
