Primary consumers are in turn eaten by fish, small sharks, corals, and baleen whales. Top ocean predators include large sharks, billfish, dolphins, toothed whales, and large seals. Humans consume aquatic life from every section of this food web.

Secondary consumers include fish, whales and the friendly basking, and whale sharks. They are the animals in the middle of the food chain. they eat plankton, shrimp and mollusks, which are primary consumers (see: primary consumers). They filter plankton and other krill into their enourmas mouth (left).

Carnivorous

Omnivores, who feed on both plants and animals, can also be considered a secondary consumer. Examples of secondary consumers: Carnivorous fish, seals, sea stars, whales, squid, some crabs ,lobsters etc. Some examples of tertiary consumers: Dolphins, sharks, killer whales, some sea birds etc.

Squid are carnivorous and their favorite foods include small fish, crabs, shrimp and other squid. A squid will stalk its prey by hiding out of sight until the animal is within range, then shoots out its arms to ensnare the food.

Is It Legal To Have A Pet Squid? Yes, squids are not prohibited in any state of the US including California.

Squid reproduce sexually. A female can produce thousands of eggs, which she stores in her ovary. In male squid, sperm is produced in the testis and stored in a sac. After male and female mate, they usually die.

After a male and female mate, the female squid lays eggs. Because of this, squid eggs are often (many times) found in clumps, and those clumps often look like a flower. Often, the male will die a short time after mating, and the female will die once she has released her eggs.

The giant Pacific octopus excretes waste through its siphon, a funnel-like hole on the side of its mantle. As a result, its poop comes out as a long, noodle-like strand.

Well, one must understand that an octopus does not defecate from their mouth, all it does is expells the waste material through its funnel or siphon that is present on the side of its mantle.

After decades and decades of research, scientists believe they’ve finally found out what vampire squids eat – and the news is pretty gross. A new study reveals that the scary looking animals diet mainly on poo, snot and dead fish. The scientific name for what they eat is ‘marine snow’.

The vampire squid hasn’t been officially evaluated by the IUCN, but it isn’t extinct and is unlikely to be endangered. It’s survived for more than 300 million years!
