Urticina Piscivora
''Urticina piscivora'', common names fish-eating anemone and fish-eating urticina, is a northeast Pacific species of sea anemone in the family Actiniidae. Description ''Urticina piscivora'' is a large anemone, growing to a maximum height of around and in diameter. The column is bright red in colour. The acontia is absent, but it has tubercles. These are not white and are arranged in circumferential rows. Normally they do not accumulate debris such as shells and sand. This anemone is made up of three layers of cells called the epidermis, the mesoglea and the gastrodermis. The epidermis forms the outermost layer, while the mesoglea is situated between the other two layers. The innermost layer, the gastrodermis also referred to as the gastrovascular cavity functions as the gut of the anemone. The gut of the fish-eating anemone is divided into compartments by sheets of tissue called “septa”. These sheets of tissue develop into tentacles on the surface of the anemone. The t ...

Urticina Felina
The dahlia anemone (''Urticina felina'') is a sea anemone found in the north Atlantic Ocean, the North Sea and the Baltic Sea. Its colour is variable, from deep red to brown or purplish, with green spots and darker tentacles. Dahlia anemones live attached to rock on the seabed from the lower tidal limit down to a depth of 100 m and also attached to other organisms. Their diet comprises small fish and crustaceans, which they immobilize by firing groups of stinging cells (cnidae) into them. Dahlia anemones are closely related to mottled anemones, and both species are usually referred to as northern red anemones. Description The base is up to 120 mm across and firmly adherent to the rock. Deep sea specimens are usually larger than inshore ones. The column is usually shorter than its diameter and its surface is covered in verrucae. There is a parapet at the top where the verrucae tend to be organised into rows. The verrucae usually have bits of gravel and debris attached to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urticina Eques
''Urticina eques'' is a species of sea anemone in the family Actiniidae. It is commonly known as the white-spotted rose anemone or strawberry anemone. Taxonomy According to one authority, the populations of ''Urticina eques'' found in the Pacific Ocean are not the same species as those in the Atlantic Ocean and should instead be considered to be conspecific with '' Cribrinopsis albopunctata'', a new species from Kamchatka. Description ''Urticina eques'' has a smooth, red column with vertical rows of white tubercles. In contrast to other similar species, the tubercles are not adhesive and do not normally attract gravel and shell fragments. There are no acontia with stinging nematocysts protruding through the body wall. The oral disk is plain red and the tapering tentacles are red and have no transverse striations. This is a large sea anemone with a diameter of up to and length. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urticina Crassicornis
''Urticina crassicornis'', commonly known as the mottled anemone, the painted anemone or the Christmas anemone, is a large and common intertidal and subtidal sea anemone. Its habitat includes a large portion of the coastal areas of the northern hemisphere, mainly polar regions, and it lives a solitary life for up to 80 years.Abbot, Donald P., Hadderlie, Eugene C., Morris, Robbert H. ''Intertidal Invertebrates of California''. Stanford, CA: Stanford University Press, 1980. Mottled anemones are similar to Dahlia anemones (''U. felina'') and both are commonly referred to as northern red anemones. Description ''Urticina crassicornis'' is biradially symmetrical and ranges from 2 - 12.7 cm tall with a width of 1 - 7.6 cm. This sea anemone has a solid basal plate which is always flat. Its column can be olive green with or without red spots, solid red, cream, or brown. It always has small, inconspicuous tubercles but no acontia. Its tubercles are not white and do not usually a ...

Urticina Columbiana
''Urticina columbiana'', common names crusty red anemone, Columbia sand anemone, sand anemone, and the sand-rose anemone, is a species of sea anemone in the family Actiniidae. Description This species can grow to 25 cm high and can reach a diameter of 1 metre, making it one of the largest species of anemone. The tentacles are long and slender, taking the shape of a red column. The tubercles on the column are big and rough, having a white colour. They are organized in circular rows which protrude from the column. Unlike other species which may accumulate matter, the tubercles do not attach to ocean debris such as bits of shell. The column is red in colour. No special spherules are present around the external rim of the oral disk beyond the tentacles. Distribution ''Urticina columbiana'' species occurs in the Pacific Ocean from Vancouver Island to Baja California Baja California (; 'Lower California'), officially the Free and Sovereign State of Baja California ( es, Esta ...

Christian Gottfried Ehrenberg (19 April 1795 – 27 June 1876) was a German naturalist, zoologist, comparative anatomist, geologist, and microscopist. Ehrenberg was an evangelist and was considered to be of the most famous and productive scientists of his time. Early collections The son of a judge, Christian Gottfried Ehrenberg was born in Delitzsch, near Leipzig. He first studied theology at the University of Leipzig, then medicine and natural sciences in Berlin and became a friend of the famous explorer Alexander von Humboldt. In 1818, he completed his doctoral dissertation on fungi, ''Sylvae mycologicae Berolinenses.'' In 1820–1825, on a scientific expedition to the Middle East with his friend Wilhelm Hemprich, he collected thousands of specimens of plants and animals. He investigated parts of Egypt, the Libyan Desert, the Nile valley and the northern coasts of the Red Sea, where he made a special study of the corals. Subsequently, parts of Syria, Arabia and Abyss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
