Without sea otters to control their population, sea urchins can proliferate unchecked. This overpopulation leads to overgrazing of kelp forests, which are vital marine ecosystems. The decline of kelp forests disrupts habitats for numerous marine species, resulting in diminished biodiversity and impacting the overall health of the marine environment. Ultimately, this imbalance can affect fisheries and coastal communities that rely on these ecosystems for their livelihoods.
Shellfish and regular fish .
There are several animals that eat sea urchins. Sea otters, sunflower stars, snails, crabs and some species of fish predate upon sea urchins.
Sea urchins are primarily considered herbivores and occupy a primary consumer position in the trophic level. They feed on algae and other plant materials, playing a crucial role in controlling algal populations in marine ecosystems. Additionally, they can be preyed upon by various predators, such as sea otters and certain fish, placing them in the food web as both consumers and prey.
Sea urchins are preyed upon by various marine animals, including sea otters, starfish, and certain fish species like triggerfish and pufferfish. Sea turtles, particularly the green sea turtle, also consume sea urchins as part of their diet. Additionally, some birds, such as gulls, may feed on them when they are exposed during low tide.
The stinkpot turtle's main predators are raccoons, skunks, otters, and large fish. They are also preyed upon by birds of prey, such as herons and eagles.
Im sure they prey upon small fish .
Long-spined sea urchins are primarily preyed upon by certain species of fish, such as triggerfish and pufferfish, which are able to consume them despite their spines. Other predators include sea otters and some sea stars, which can pry them open to access the soft tissue inside. Additionally, some crabs and birds may also feed on them during low tide when they are exposed.
Prey.
Leopard seals, Killer whales, and humans prey upon seals.
Deer are herbivores; they forage for grasses, leaves, barks, and twigs. They do not prey upon other animals. Other animals prey upon them.
Great White sharks are pure carnivores. They prey upon fish (like Tuna, Rays etc), other smaller species of Sharks, dolphins, porpoises, seals, sea lions, sea turtles, sea otters and even sea birds. They prefer prey that has a high content of energy rich fat.
