. Dangerous marine animals. Marine animals. 24 DANGEROUS MARINE ANIMALS GIANT DEVIL RAY OR MANTA (Manta birostris Donndorff). (Fig. 6, Top). This giant ray may attain a spread of more than 20 ft., and a weight of more than 3500 lbs. It does not possess a caudal sting. When harpooned, it is able to tow a small launch for several hours. The manta is not aggressive and is dangerous only because of its huge size. Several deaths have been reported of helmet divers whose airlines became fouled in the cephalic fins and "wings" of mantas that apparently came over to investigate the bubbles.

Top: Giant Devil Ray or Manta, Manta birostris Donndorff. (Baergh) Bottom: Great Barracuda, Sphyraena barracuda (Walbaum). (Hon) most sharks, their skin is covered by coarse dermal denticles which can inflict a severe abrasion of the skin if one were to brush up against them. They are generally seen swimming or basking near the surface of the water with the tips of their long pectoral fins curling above the surface. Occasionally, they are seen leaping out of the water and falling back into the water with a tremendous splash. Mantas are primarily plankton feeders, but may eat crusta- ceans and small fishes, at times. Their color is reddish or olivaceous- brown to black above, and light beneath. Mantas are found in tropical-subtropical belts in both hemispheres. Although some investigators believe that there may be as many as ten different.
