[78] Georgia keeps four whale sharks: two females, Alice and Trixie, that arrived in 2006,[83] and two males, Taroko and Yushan, that arrived in 2007.
Fortunately for many animal species (including humans), the natural food of the large whale shark is mainly plankton, although occasionally includes other small animals such as krill, jellyfishes, sardines, anchovies, mackerels, squids, and crabs, as long as they are small.

[24][25][26][27] The maximum length of the species is uncertain due to a lack of detailed documentation of the largest reported individuals. [9][10][11], Evidence suggests that males grow faster than females in the earlier stages of life but ultimately reach a smaller maximum size. Philippines, Cebu. The largest confirmed individual had a length of 18.8 m (62 ft).
[8] The whale shark holds many records for size in the animal kingdom, most notably being by far the largest living nonmammalian vertebrate.

[54], Whale sharks are known to prey on a range of planktonic and small nektonic organisms that are spatiotemporally patchy.
[8], Large whale sharks are difficult to measure accurately, both on the land and in the water. The study found an age of 50 years for a 10 m (33 ft) female and 35 years for a 9.9m male. Bagan fishermen see whale sharks as good luck and often feed them baitfish. These denticles serve to protect the eye from damage, along with the whale shark's ability to retract its eye deep into its socket.

Occasionally, the whale shark will feed on some small crustaceans, squid and larger plants, but its diet is largely built on some of the smallest ocean creatures. [9][11][22][23] Limited evidence, mostly from males, suggests that sexual maturity occurs around 8 to 9 meters (26 to 30 ft) in length, with females possibly maturing at a similar size or larger. But the whale shark feeds mostly on microscopic and small prey. It is the sole member of the genus Rhincodon and the only extant member of the family Rhincodontidae, which belongs to the subclass Elasmobranchii in the class Chondrichthyes.
Whale sharks might change their feeding behavior according to prey abundance and composition to maximize the relationship between energy expended with caloric intake.
