![]() Whale sharks are part of the shark order Orectolobiformes, also known as carpet sharks. Size Compared to Closest Relatives (Orectolobiformes) Let’s explore the size of whale sharks compared to other marine animals, including their closest relatives and other marine giants like blue whales. Whale Shark Size Relative to Other Sharks and Marine Animals This suggests that the largest whale sharks are generally females. Males tend to reach an average adult whale shark size of 8.0-9.0 meters, while females continue to grow to an average size of 12-14.5 meters. A recent study proposed that male and female whale sharks may have significantly different growth trajectories. Maturation in whale sharks is thought to occur at approximately 9 meters in length. Relatively few studies examine substantial populations of adult whale sharks of both sexes. The majority of research on this species is conducted at coastal feeding sites, where juvenile males typically dominate in a 3:1 ratio. ![]() A more practical question might be, "How large is the average adult whale shark?" Surprisingly, this question is subject to a bias unique to whale sharks. Maximum sizes provide only one perspective on whale shark size. While the fossil record is incomplete, it appears that the whale shark holds the all-time record for size. The extinct Jurassic bony fish, Leedsichthys problematicus, is another contender, but its five known fossil specimens were estimated to be between 8.0 and 16.5 meters in total length. The famous Miocene mega-predatory shark, Otodus megalodon, may seem comparable in size, but its maximum size range is estimated to be between 14.2 and 15.3 meters. However, comparing whale shark size to extinct species is challenging due to the poor fossilization characteristics of sharks. Whale sharks are not only the largest extant fish species, but they might also be the largest fish to have ever existed. Other records of whale shark size also hover around the 18-meter mark, with some less reliable reports claiming whale sharks to be as much as 20 meters long. ![]() The largest reliable record of a whale shark is 18.8 meters (62 ft) in total length. Let's dive in and see how these giants measure up! How Big is a Whale Shark? Understanding Whale Shark Sizeĭetermining the exact size of whale sharks is no simple task, but the question "how big is a whale shark?" has fascinated researchers and marine enthusiasts alike. ![]() Here we'll explore the size of whale sharks relative to other marine animals, the average size of adult whale sharks, the potential differences between male and female growth, and comparisons to their closest relatives and other marine giants. Although they are protected in international waters and by laws of certain countries, they travels often through unregulated waters and are still being fished all over the world.Whale sharks are the largest fish in the ocean, leaving us in awe of their incredible size. Overfishing has the real potential to wipe out large numbers of giant oceanic mantas due to the fact that they live so long and reproduce so little. Their size make them particularly susceptible to entanglement in fishing nets even when they are not voluntarily fished out. Their gills is still in high demand mostly by the traditional chinese medecine market. The Manta Trust and Marine Megafauna foundations are both working globally to research and protect the mobulae family and their habitats. The International Union for Conservation of Nature (IUCN) declared manta rays as ’vulnerable’ in 2011. ![]() All of this combined make their reproduction quite slow! The mother will usually have two years elapse between pregnancies. Manta-mums usually carry only one pup, but 2 pups have already been recorded. They are born independent after a 12-13 months gestation period. Manta rays can live as long as 50 years and are ovoviviparous, which means that they start development in an egg and hatch within the mother's body. ![]()
