The whale shark (Rhincodon typus) is a slow-moving shark and is regarded as the largest extant fish species. They are also referred to as filter feeding sharks. They can grow to a size of about 12.65 m (41.50 feet), with a weight measuring at 21.5 tonnes (47,000 lb), there are unverified reports of significantly larger whale sharks. There have been claims regarding the length measuring at 14 m (46 feet), with the weight of around 30 tonnes (66,000 lb). These sharks have the honor of being called a mammoth size and are by far the largest non-mammalian vertebrate, rivaling many of the largest dinosaurs by weight. It is the only member of genus and the Rhincodontidae and it belongs to the subclass Elasmobranchii and the class Chondrichthyes. These species are believed to have been evolved some 60 million years ago.

The whale sharks are known to reside in the warm oceans and tropical waters in the wide sea with a lifespan of about 70 years. In spite of their larger mouth, they mainly feed on microscopic plants and animals including plankton. They were identified at the start of 19th century in 1828 when the specimen of about 4.6 m (15.1 feet) was found to harpoon in Table Bay, South Africa.

These species inhabits all throughout warm-temperate and tropical waters. They also migrate each spring to the continental shelf which is at the central coast of Australia. Because of the coral spawning of the region’s Ningaloo Reef, there is abundant of plankton supply. Although occasionally, whale sharks are also found in the Great Rann of Kutch, Ningaloo Reef, Utila, Pasacao, Honduras, Yucatan, Isla Mujeres, Btangas, and Donsol. The countries include India, Philippine, Brazil, Mexico, Western Australia, Indonesia, South Africa, Tanzania, Islands of Pemba, Zanzibar, and Mafia. These animals are capable to dive deep into the depths of around 1,286 m (4,219 feet). The largest specimen measured at 11 – 12 m(36 – 39 feet), together with a weight measuring at 7,000 kg (15,000lb). One of the largest concentrations of whale sharks were found in the Yucatan coast of Mexico, comprising more than 400 species gathered in a single place to feed on spawn from little tunny.

What Do Whale Sharks Eat

These sharks are the filter feeders together with the basking sharks and megamouth sharks. They primarily feed on plankton, krill, Christmas Island red crab larvae, algae, and tiny nektonic life including vertebrates and squid. Whale sharks also feed on small fish and clouds of eggs. The filter pads facilitates in separating the food from water. Food separation in these sharks is facilitated by cross-flow filtration in which the water flows along with filter pad surface, before being extracted outside. They are considered to be energetic feeders, believed to focus on a large quantity of fish and plankton.
