Overview
The ocellated eagle ray (or Aetobatus ocellatus) inhabits warm, coastal waters of tropical and subtropical regions throughout the Indo-Pacific, and parts of the eastern Pacific. These rays are typically found in shallow bays, coral reefs, and sandy or muddy seafloors. They have a dark dorsal side covered in bright white spots, a contrasting white underside, a flattened, rhomboid-shaped body, and long, pointed pectoral fins resembling wings. They also have a long, whip-like tail. Adult males measure 1.5m to 2.0m and weigh 20kg to 35kg. Females are larger, measuring up to 2.5m and weigh up to 90kg.

Critically endangered
The ocellated eagle ray is considered Endangered. As a slow-growing species with low reproductive rates, it is especially vulnerable to overexploitation. It is frequently caught as bycatch in nets and lines intended for other species. In some regions, it is also hunted for its meat, cartilage, and gill rakers. Habitat degradation, particularly the destruction of coral reefs, seagrass beds, and coastal nursery areas, further threatens its populations. Pollution, boat traffic, and climate change–related stressors, make it difficult for populations to recover. Trade in the ocellated eagle ray is regulated to prevent overexploitation. Several countries have fishing regulations, protected areas, and bycatch reduction strategies to safeguard the species. Research programs are using satellite and acoustic tagging to better understand their movements, habitat use, and behaviour. Education campaigns and eco-tourism initiatives help raise awareness and reduce human impacts. While direct reintroduction efforts are limited, preserving healthy habitats and reducing human pressures support the long-term survival of ocellated eagle ray populations.

Social & reproduction
Keeper notes
Ocellated eagle rays may be solitary or loosely social. They are often seen in groups for the purposes of feeding, breeding and travelling. Breeding is seasonal in some regions, often tied to warmer water temperatures and food availability: late spring to early summer is typical. They are thought to reproduce every two years, though reproductive cycles may vary by region and environmental conditions. For courtship, males will follow and nip at females before aligning themselves by interlocking their claspers and transferring sperm via cloacas. Gestation typically lasts around 1 year, and females give birth to 1 to 4 pups per litter. Newborns are miniature versions of adults, measuring approximately 30–45cm and are immediately independent. Ocellated eagle rays reach sexual maturity at around 3 to 6 years of age, with males generally maturing earlier than females.

Animal facts
- Ocellated eagle rays are known for ‘breaching’ - jumping out of the surface of the water, sometimes up to 1m high.
- Ocellated eagle rays have specially adapted teeth that form a flat, rasp-like surface for crushing shells.
- Ocellated eagle rays have venomous spikes in their long, whip-like tail.
- Each ocellated eagle rays have a unique pattern of spots that can be used to identify them like a fingerprint.
- Ocellated eagle rays are named after eagles because of their large wing-like fins.
