Can anyone name some ocean omnivores?

Question

Well, I've been trying to think of some omnivores that live in the ocean, but so far none have come to me. Can any one name some for me? Thanks.

Answer 1

Salt water crabs-they consume seaweed and small marine vertebrate (minnow, shrimp, etc)
Salt water lobster too eats the same as the crab.
Sea otter eats urchin and seaweed as well.
Sea turtles eats algea and jellyfish too.
There may be others, try searching on the website for varieties. Who knows maybe you'll stumple across more than we realize.

Answer 2

There are so few plants in the ocean that there aren't going to be many anyway. Seagrass is the only plant I can think of, grazed by manatees and dugongs. Seaweed and kelp are protists, macroalgae, not plants.

Though I imagine what eats that would be a herbivore too. The way the food web works is that it starts with the photosynthesising phytoplantkon. Those are eaten by zooplankton, in term eating by larger zooplankton, for example, krill, eaten by whales, birds and fish. The food web continues from there.

Your best bet is to identify something that eats phytoplankton and zooplankton indiscriminately. Some filter feeders may well be omnivorous.

Coral contain symbiotic dinoflagellates within their polyps- photosynthesising algae. Parrotfish and crown-of-thorns starfish that eat coral could therefore be said to be omnivorous, even though they prey higher up the food chain than the still-living dinoflagellates.

Phytoplankton constitute near enough all of the ocean's productivity, which is approximately half of that of the whole world. And only 3% of the world's biomass is in the oceans, which just goes to show how how high the turnover is. There are no trees in the ocean to contain it. There are no niches that can exploit both primary producers and their consumers at once. This is why there are so few omnivores in the ocean.

Answer 3

Marine Omnivores

Answer 4

I agree with the person that said sea turtles, certain kinds, marine otters, and certain types of whales. Also, polar bears sometimes consume seaweed when food is scarce at certain times of the year according to several wildlife documentaries I was watching. Ordinarily they are strict carnivores eating mainly seals such as the ringed seal, and occasionally small whales too.

The leatherback sea turtle is an omnivore. There are seven types of sea turtles and the green sea turtle starts out eating invertebrates but then as a mature adult is strictly vegetarian. Will research the other five kinds to get back to a more specific example.

Here we go: flatback sea turtles, Olive Ridley, and hawksbill sea turtles are all omnivores.

Answer 6

Sea otters
some fish are
sometimes manatees and dugongs are known to eat something besides the seagrasses and marine plants
that's all i can think of right now

Answer 7

Mabye an otter. I think they eat seaweed and meat like urchins, but Im not positive. And maybe whales that feed on phytoplankton and zooplankton.

Answer 8

sea turtles eat meat as in jellyfishes and algae.

Sea otters eat sea urchins and algae.

Whales eat plankton made up from photosynthetic cells as well as larvae and krill.

Answer 9

to the above answer, there will be one species less, the south koreans have just announced they intend to hunt minke whales for 'scientific purposes'.

Answer 10

omnivores eat plants and meat unfortunly there are none only carnavores
