Are sea anemones plankton?

We generally focus on sea anemones for the cleaning shrimps and fishes that hide within their tentacles. But anemones themselves are plankton feeders and their tentacles are actually plankton pickers.

Are sea urchins herbivores or omnivores?

Sea urchins feed mainly on algae, so they are primarily herbivores, but can feed on sea cucumbers and a wide range of invertebrates, such as mussels, polychaetes, sponges, brittle stars, and crinoids, making them omnivores, consumers at a range of trophic levels.

Are sea urchins plants or animals?

sea urchin, any of about 950 living species of spiny marine invertebrate animals (class Echinoidea, phylum Echinodermata) with a globular body and a radial arrangement of organs, shown by five bands of pores running from mouth to anus over the test (internal skeleton).

Are soft bodied or shelled animals?

Molluscs, one of the largest groups in the animal kingdom, have soft bodies and generally have a hard shell for protection – so they are often called “shellfish”. Most molluscs are found in the ocean, but many can be found in freshwater and on land. Worldwide there are about 100,000 species of marine molluscs.

Are there any animals without skin?

Babirusa. Also called deer-pigs, these mostly hairless animals are members of the pig family and are found in Indonesia. Aside from their nearly bare skin, babirusa are distinctive for their dual pairs of teeth, specifically the upper pair that appears to be growing out of its snout.

Can you grow a madagascar palm from a cutting?

Cuttings. To grow “Madagascar Palm” from offsets, use a sterile, sharp knife or pair of scissors. Remove one of the circular offsets from the trunk of the main plant, and allow it to callous for several days before placing on well-draining soil. Water whenever the soil has dried out completely.

Is a sea anemone living or nonliving?

Corals consist of small, colonial, plankton-eating invertebrate animals called polyps, which are anemone-like. Although corals are mistaken for non-living things, they are live animals. Corals are considered living animals because they fit into the five criteria that define them (1.
