Sertularella polyzonias is a branching colonial hydroid in the family Sertulariidae. [2]
This hydroid branches rather sparsely and irregularly compared with Sertularella gayi . The main stems and side branches are thin, wavy, and of a pale straw colour. As in all Sertularella species, the side branches support alternate hydrothecae, one to each internode. The hydrothecae are bulbous at the base and become narrower towards the rim which has four cusps, and an operculum that consists of four triangular flaps. The gonothecae are generally ovate in shape and slightly rugose in texture. A raised tubular structure with four vertically projecting denticles surrounds the aperture. Although the male and female gonothecae are similar in shape the male is considerably smaller and is white, whilst the female is yellow in colour. Colonies are typically 40–50 mm in height. [3]
Reported widely from the Atlantic Ocean and Mediterranean Sea, shallow sublittoral to considerable depths. [4]
Spoonbills are a genus, Platalea, of large, long-legged wading birds. The spoonbills have a global distribution, being found on every continent except Antarctica. The genus name Platalea derives from Ancient Greek and means "broad", referring to the distinctive shape of the bill. Six species are recognised, which although usually placed in a single genus have sometimes been split into three genera.
Macrothylacia rubi, the fox moth, is a lepidopteran belonging to the family Lasiocampidae. It was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.
Angerona is a monotypic moth genus in the family Geometridae erected by Philogène Auguste Joseph Duponchel in 1829. Its only species, Angerona prunaria, the orange moth, was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.
The red porgy, or common seabream, is a species of marine ray-finned fish in the family Sparidae. It is found in shallow waters on either side of the Atlantic Ocean, being present on the western coast of Europe and the Mediterranean Sea as well as the eastern coasts of North and South America and the Caribbean Sea. It feeds on or near the seabed and most individuals start life as females and later change sex to males.
Viviparus viviparus is a species of large freshwater snail with a gill and an operculum, an aquatic gastropod mollusk in the family Viviparidae, the river snails.
Doris verrucosa is a species of sea slug, a dorid nudibranch, a marine gastropod mollusk in the family Dorididae.
Pocillopora is a genus of stony corals in the family Pocilloporidae occurring in the Pacific and Indian Oceans. They are commonly called cauliflower corals and brush corals.
Flustra foliacea is a species of bryozoans found in the northern Atlantic Ocean. It is a colonial animal that is frequently mistaken for a seaweed. Colonies begin as encrusting mats, and only produce loose fronds after their first year of growth. They may reach 20 cm (8 in) long, and smell like lemons. Its microscopic structure was examined by Robert Hooke and illustrated in his 1665 work Micrographia.
Tubularia indivisa, or oaten pipes hydroid, is a species of large hydroid native to the northeastern Atlantic Ocean, the North Sea, Norwegian Sea, and the English Channel. The conical solitary polyps are found on dull yellow unbranched stems that reach 10 to 15 cm in height with a diameter of 1.5 cm (0.59 in). They may be fused to a small number of other individual stems at their bases. The pinkish to red polyps resemble flowers, having two concentric rings of tentacles, with the outer rings being paler and longer than the inner ring. At the center is a pale pink gonotheca. They are preyed upon by nudibranchs.
Obelia longissima is a colonial species of hydrozoan in the order Leptomedusae. Its hydroid form grows as feathery stems resembling seaweed from a basal stolon. It is found in many temperate and cold seas world-wide but is absent from the tropics.
Sertularella is a genus of hydroids in the family Sertulariidae.
Trinchesia foliata is a species of sea slug, an aeolid nudibranch, a marine gastropod mollusk in the family Trinchesiidae.
Tillus elongatus is a species of beetle in the Family of checkered beetles Cleridae. It is found in the Palearctic. The “Holz” in the German common name Holzbuntkäfer indicates that these checkered beetles are found in wood. Although Tillus elongatus can reach up to a size of 1 cm long, the beetle is rarely seen by humans, as it primarily resides hidden in the wood of trees. The colouration of the males differs from that of the females.
Anthias anthias, the swallowtail sea perch or marine goldfish is a species of marine ray-finned fish from the grouper and sea bass family Serranidae. It is native to the eastern Atlantic Ocean and the Mediterranean Sea where it is associated with reefs. It is found in the aquarium trade.
Sertularella gayi is a branching colonial hydroid in the family Sertulariidae.
Sertularella decipiens is a branching colonial hydroid in the family Sertulariidae.
Sertularella inconstans is a branching colonial hydroid in the family Sertulariidae.
Sertularella ellisii is a branching colonial hydroid in the family Sertulariidae.
Halecium muricatum, commonly known as the sea hedgehog hydroid, is a species of hydrozoan in the family Haleciidae. It occurs mainly in arctic and northern temperate waters, in both the Atlantic and Pacific Oceans.
Halecium halecinum, commonly known as the herring-bone hydroid, is a species of hydrozoan in the family Haleciidae. It is native to the eastern Atlantic Ocean, the western Atlantic Ocean and the eastern Pacific Ocean.
