Directory of Marine Fish Sponges and Anemones These invertebrates are an integral part of the reef ecosystem. Anemones are soft-bodied creatures with flowing, stinging tentacles for catching prey. Sponges have a more rigid body structure and are filter-feeders. Both are sometimes known as sessile invertebrates because, like corals, they anchor themselves to the reef. Sponges […]
There are few more diverse invertebrate groups than the mollusks. Marine gastropod mollusks possess a protective shell and a “foot” for locomotion, just like the land snails.
These plants are more decorative than functional. However, when planted in containers on the marginal shelf—the ledge around the inside of preformed ponds, about 12 in (30 cm) below the surface—they can provide retreats for young fish. Marginals can also be grown as edging plants, giving the pond a more informal look and creating a barrier that makes it more difficult for predators to reach the fish. Some marginals trail down into the water, which helps to hide the perimeter from view. All the plants featured here are suitable for temperate climates, but some will benefit from protection in winter.
Starfish are the best-known echinoderms, but the group also features feather and brittle stars, as well as sea urchins and sea cucumbers. While they vary in shape, all these creatures have an internal body structure formed from calcium and tube feet that enable them to move over the seabed.
