| The rocky seabed is covered in jewel anemones, dead man's fingers and hydroids. |
|
| It feeds mainly on sponges, but also takes tunicates, algae, zoantharians, gorgonians, hydroids, bryozoans, and seagrasses. |
|
| Turning on our torches, the walls came alive with a thick covering of hydroids, sponges and anemones. |
|
| On the walls are a riot of soft corals, sponges, hydroids and anemones in all shapes and sizes. |
|
| The leatherjackets and wrasses continued their work below them, as tiny tubularia hydroids waved their tentacles from the hull. |
|
| There were dense walls of soft corals, sponges, anemones and hydroids, nudibranchs, creepy-crawlies and lots of fish. |
|
| A sample obtained in June was examined and found to consist mainly of hydroids and erect branching polyzoans bound up among shell detritus and argillaceous matter. |
|
| He and his colleagues worked primarily on hydroids and planarians. |
|
| In nature scallops settle on epibenthic hydroids and other filamentous organisms, which likely would be vulnerable to intensive raking. |
|
| They're carnivorous, feeding on sponges, tunicates, bryozoans, hydroids, and sea anemones. |
|
| In colonial hydroids, such as Tubularia, there is a series of branching stems, each of which bears a hydranth on its end. |
|
| In hydrozoans, the polyp phase is more conspicuous than the medusa phase in groups such as hydroids and hydrocorals. |
|
| Hydrozoan polyp colonies, called hydroids, are prostrate, bushy, or feathery in form. |
|
| Colonies may be mistaken for hydroids, corals, or even seaweeds. |
|
| As the roiling backwash streamed past, it scoured around me, and when the froth cleared, there beneath my feet were multitudes of clams, all small and without hydroids. |
|
| Aside from its temporary and permanently resident fish, the underside is decorated with sponges, hydroids, tunicates, tube worms, cup corals and anemones. |
|
| Cnidarians are incredibly diverse in form, as evidenced by colonial siphonophores, massive medusae and corals, feathery hydroids, and box jellies with complex eyes. |
|
| Well-studied examples occur in the hydractiniid hydroids, which encrust hard substrata with stolons that serve as tube-like connections between feeding polyps. |
|
| The third genus, Atubaria, lives on hydroids. |
|
| In all replicates, moon snails preferred clams without hydroids over clams with hydroids. |
|
|
|
| Among the most remarkable are the nudibranchs that eat anemones and hydroids and then sequester certain types of immature, undischarged cnidae from the prey. |
|
| The small blue colonial hydroids, known as Velella Velella or By-The-Wind-Sailors, shoal in vast numbers. |
|
| This makes it quite similar with other defenseless creatures of the ocean waters like hydroids and jellies. |
|
| The bottoms and walls of the underwater caves are characterized by a very special fauna of hydroids, colorful sponges and bryozoa as well as soft corals and clinid fishes. |
|
| At depths beyond 9 m, anemones and hydroids abound. |
|
| Rocky bottoms more than 3 m deep are dominated by sponges and hydroids. |
|
| Snails feed on epiphyte vegetation on the surface of the leaves, amphipods and small shrimp on detritus, encrusting bryozoans on suspended food particles, and hydroids on small organisms in the water. |
|
| Each receiver remains underwater for a period of approximately 12 months. This is long enough to allow colonisation by sessile animals such as hydroids, tunicates and bivalves. |
|
| Bryozoans, like hydroids, are small plant-like colonial animals. |
|
| Among the fossils are a variety of creatures from sponges, worms and nautiloids to solitary hydroids, also known as the flowers of the sea. |
|
| Most neomenioids are predators on octocorals or hydroids, whose nematocysts are seen in their midguts. |
|
| Most dendronotaceans do, however, feed on cnidarians, ranging from hydroids to sea anemones, sea whips, and sea pens, and scyphistomas of scyphozoan jellyfishes. |
|
| Home to the pretty cuckoo wrasse, the fearsome-looking wolf fish, deeplet sea anemones, light bulb sea squirts, edible sea urchins and bottle brush hydroids. |
|
| Other abundant groups included actinarian and zoanthid anemones, bryozoans, caprellid and gammaridian amphipods, clionid sponges, hydroids, ophiuroids, and tunicates. |
