Behavioural Adaptations of The Ornate Eagle Ray

Behavioural Adaptations
One of the behavioural adaptations of the Ornate Eagle Ray is that it stays close to the seafloor, in fairly shallow waters. It stays close to the seafloor because thats where most of the food that it eats lives. (3) It also swims close to the bottom of shallow waters because then it doesn't encounter predators as often because it blends in so well to the seafloor. (8) It doesn't usually go beyond depths of 110m. (5)  Rays mating behaviour is that one female will be followed by a chain of males, one of them hoping to win her as a mate. (7)

Structural Adaptations

The Ornate Eagle Ray feeds on bottom dwelling animals like mollusks and crustaceans, they use their rostral lobes to grab it and then use their flattened plate teeth to crush them. (2) To avoid predators like sharks, they can blend into their surroundings because of the colour of their body and the flat nature of their body. They also use their ability to swim fast to out swim their predators. (8) The reproduction method Ornate Eagle Rays use is Ovoviviparity, which means the embryo develops inside eggs in the mothers body, and are born live. (5)(6)
