shit-talking sharks n rappin rays

Evidence of sharks or rays producing sound has not been documented, past researchers have noted, suggesting that such creatures do not have the biological tools to do so. But there appears to be some exceptions. The researchers in this new effort have obtained a video/sound recording of one mangrove whipray producing sound as it swam over a reef off the coast of the Gill Islands, which are part of Indonesia. They have also observed another video/sound recording of another whipray that turned up on Instagram and also a video of a cowtail stingray making sounds.
