What is the sleeping pattern of a whiptail ray?

Whiptail rays exhibit a unique sleeping pattern characterized by periods of rest where they remain motionless on the ocean floor, often partially buried in sand. During this time, their metabolic rate decreases, and they may stay in a semi-alert state to evade predators. Unlike some fish, whiptail rays do not have eyelids, so they rely on other adaptations to manage light and activity levels while resting. Their sleeping behavior allows them to conserve energy while remaining vigilant in their environment.
