Red List Criteria
The development and implementation of management plans (national and/or regional e.g., under the FAO International Plan of Action for the Conservation and Management of Sharks: IPOA-Sharks) are required to facilitate the conservation and sustainable management of all chondrichthyan species in the region. See Anon. (2004) for an update of progress made by nations in the range of A. vespertilio.
Relevance to Humans and Ecosystems
Ornate eagle ray
The ornate eagle ray or reticulate eagle ray (Aetomylaeus vespertilio) is a species of fish in the Myliobatidae family. It is found in Australia, China, India, Indonesia, Malaysia, Maldives, Mozambique, Taiwan, and Thailand. Its natural habitats are open seas, shallow seas, subtidal aquatic beds, and estuarine waters. It is usually found at depths of 5-50m.
The ornate eagle ray has a clearly distinct pattern of reticulate dark lines and rings on its back. If the extremely long tail is unbroken, it can considerably add to the maximum body length of 4m.
Lacking spine on the tail, it is deemed harmless to humans.
