Tiger sharks have only one recorded natural predator, the orca. [6] It is considered a near threatened species because of finning and fishing by humans. [1] The tiger shark is second only to the great white in recorded fatal attacks on humans, but these events are still exceedingly rare. [7] [8]
Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
[3] [4] The great white shark (bottom) is one of the top marine predators; however, the orca (top) is known to prey upon them. Thus, great white sharks are not true apex predators. Despite coexisting the majority of the time, confrontations may occur in stressed environments when both species compete for limited resources.

Various carnivorans, with feliforms to the left, and caniforms to the right. Carnivora is an order of placental mammals that have specialized in primarily eating flesh. Members of this order are called carnivorans, or colloquially carnivores, though the term more properly refers to any meat-eating organisms, and some carnivoran species are omnivores or herbivores.
According to the Shark Research Institute, there are over 400 plus species of shark around the world, which include great white sharks, tiger sharks and bull sharks.
The genomes of the Tasmanian devil, killer whale, polar bear, leopard, lion, tiger, cheetah and domestic cat were analysed, and shared positive selection for two genes related to bone development and repair (DMP1, PTN), which is not seen in omnivores or herbivores, has been found. This indicates that a stronger bone structure is a crucial ...
