Flexible horns are used to direct plankton and water into the manta’s very broad and wide mouth.


Manta Ray

During embryonic development, part of the tissue that becomes the pectoral fins of the manta ray breaks away and moves forward, surrounding the mouth. This structure develops into horns. These flexible horns are used to direct plankton and water into the manta’s very broad and wide mouth. To make it more streamlined when swimming, it is able to curl its horns up.


  • The manta ray is most easily recognized by its large pectoral “wings.”
  • It also has “horns” that protrude from either side of its head.
  • The manta ray is usually black above and white below, but can be blue on its back.
