A 20-food Wide Manta Ray
Look how massive this manta ray is! In fact, this unusual sea creature weighed 5000 lb. These guys are found in tropical and subtropical waters, and they can literally fly through the water. The manta ray in this photograph got entangled in an anchor chain of the boat. The International Union for Conservation of Nature classified manta rays as vulnerable species. Fishing nets and pollution are the biggest threats to these massive creatures.
