It has a vestigial spiracle behind the eye, which is an evolutionary remnant of its common ancestry with bottom-dwelling (benthic) carpet sharks. Whale sharks have a broad, flat head, relatively small eyes, five large gill slits, two dorsal fins, two long pectoral fins, two pelvic fins, one anal fin and a large sweeping tail.Newborns measure 21 to 25 inches (53-64 cm) long.The average length is between 18 and 32 feet (5.5-9.8 m).The largest accurately measured whale shark was 61.7 feet (18.8 m).Because of its size and cartilaginous skeleton, it does not fossilize well and in life it is very difficult to weigh accurately. The whale shark is the largest fish in the world and the largest fish known to have lived on this planet.Beginning Environmental Leadership Program.Dolphin Coast Presented by Margaritaville by Wyndham.

Thus, the IUCN has labelled the species as vulnerable.Shows & Presentations Shows & Presentations Although they have few natural predators, they are subjected to great threats due to human activities like fishing. They feed on massive quantities of sea jelly. These fish inhabit the world’s tropical and temperate oceans.

Due to their unique shape, the fish can attain a height equivalent to their length. Adults of this species weigh around 2.3 tons and can grow up to a maximum length of 10.8 ft. The Mola mola is the world’s largest living bony fish. The conservation status of the species is yet to be evaluated. The sharptail mola feeds on a wide variety of species including annelids, sponges, fishes, etc. The fish can attain a length of about 11 feet and weigh as much as 2 tons. Since the species is elusive in nature, it is rarely sighted and hence little understood. The Masturus lanceolatus is a mola species that lives in the world’s tropical and temperate marine waters. The fish is found in the oceanic waters of the Southern Hemisphere where it preys on salps.

However, it is ranked as one of the biggest fish species known to us. The Mola tecta have been recently discovered and hence little is known about its behavior.
