Spotted Eagle Ray
Spotted eagle rays can be found globally in tropical regions and are most commonly seen alone, but occasionally swim in groups. Rays are ovoviviparous, the female retaining the eggs then releasing the young as miniature versions of the parent. The spotted eagle ray is listed as Near Threatened on the IUCN Red List of Threatened Species.
Southern Stingrays
At Rum Point Channel in Grand Cayman Island squadrons of the southern stingrays congregate at first light as the sun rises and up to 100 of these circle around together flying over the sand bars looking for food in a swarm.
