Whale sharks' lifespans are estimated to be between 80 and 130 years, based on studies of their vertebral growth bands and the growth rates of free-swimming sharks. [9] [10] [11] 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.
Orcas off the coast of Mexico have devised a cunning strategy to hunt and kill whale sharks, and marine scientists have documented ... to predators. While an orca versus whale shark matchup may ...
The killer whale pod in Mexico hunts and attacks much larger whale sharks by targeting them from below, a study finds Killer Whales Are Hunting Whale Sharks — the Largest Fish in the World, New ...
In other parts of the world, orcas have preyed on broadnose sevengill sharks, [75] whale sharks, [76] [77] and even great white sharks. [75] [78] Competition between orcas and white sharks is probable in regions where their diets overlap. [79] The arrival of orcas in an area can cause white sharks to flee and forage elsewhere.
The otodontid sharks have been considered to have been ectotherms, so on that basis megalodon would have been ectothermic. However, the largest contemporary ectothermic sharks, such as the whale shark, are filter feeders, while lamnids are regional endotherms, implying some metabolic correlations with a predatory lifestyle.
The distinct smell of shark liver in the air and gulls diving toward a slick on the water’s surface, as well as a second shark carcass measuring 3.55 meters (11.6 feet) discovered nearby, led ...

In the ocean food chain, large sharks generally only have to worry about keeping orcas at bay — but a new study suggests the apex predators may have to watch out for their own.. Researchers have ...
