Similar to white sharks, salmon sharks have a slow growth and reproduction rate, making them susceptible to overfishing and overexploitation. They are considered least concern, however juvenile salmon sharks are extremely susceptible to temperature changes in coastal waters. This means that further ocean warming can severely impact the species.
Marks made by cookiecutter sharks have been found on a wide variety of marine mammals and fishes, and on submarines, undersea cables, and human bodies. It also consumes whole smaller prey, such as squid. Cookiecutter sharks have adaptations for hovering in the water column, and likely rely on stealth and subterfuge to capture more active prey ...
For example, a large school of fish can cause nearby sharks, such as the lemon shark, to enter into a feeding frenzy. [1] This can cause the sharks to go wild, biting anything that moves, including each other or anything else within biting range. Another functional explanation for feeding frenzy is competition amongst predators. [2]
The tiger shark is an apex predator [35] and has a reputation for eating almost anything. [7] These predators swim close inland to eat at night, and during the day swim out into deeper waters.

Avoid splashing around in the water. Don’t swim at dusk or dawn. Sound, color and blood were listed as primary alluring components for sharks by the National Oceanic and Atmospheric ...
Large populations of gulper sharks must be built over long periods of time. Gulper life strategy is also consistent with their trophic level and place in the deepwater community. They are tertiary consumers with no apparent predators, so their biological gear toward competition is an ecologically sound strategy. [12]
