![]() Whale sharks have five large pairs of gills. The spiracles are located just behind the eyes. Whale shark mouths can contain over 300 rows of tiny teeth and 20 filter pads which it uses to filter feed. A 12.1 m (39.7 ft) whale shark was reported to have a mouth 1.55 m (5.1 ft) across. Unlike many other sharks, whale shark mouths are located at the front of the head rather than on the underside of the head. Whale sharks possess a broad, flattened head with a large mouth and two small eyes located at the front corners. In addition, its filter feeding habits are not unlike those of baleen whales.

The species was distinguished in April 1828 after the harpooning of a 4.6 m (15 ft) specimen in Table Bay, South Africa. They feed almost exclusively on plankton and small fishes and pose no threat to humans. Whale sharks have very large mouths and are filter feeders, which is a feeding mode that occurs in only two other sharks, the megamouth shark and the basking shark. Studies looking at vertebral growth bands and the growth rates of free-swimming sharks have estimated whale shark lifespans at 80–130 years. The whale shark is found in open waters of the tropical oceans and is rarely found in water below 21 ☌ (70 ☏). Before 1984 it was classified as Rhiniodon into Rhinodontidae. 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. The whale shark holds many records for size in the animal kingdom, most notably being by far the largest living nonmammalian vertebrate. The largest confirmed individual had a length of 18.8 m (61.7 ft). The whale shark ( Rhincodon typus) is a slow-moving, filter-feeding carpet shark and the largest known extant fish species. Rhinodon pentalineatus Kishinouye, 1901."Sharks of this size are quite rarely seen so it is unbelievably great news to know that other females are growing to a good size and reproducing," she said.

"She is an absolutely beautiful and magnificent being that both commands and deserves respect."
