List Of Sponges Of Ireland
There are 290 species of sponges recorded in Ireland, although the true figure is thought to be close to 500; 134 species were recorded off Rathlin Island alone. Sponges are animals of the phylum Porifera; sessile aquatic animals without true tissues.

Demospongiae
Demosponges (Demospongiae) are the most diverse class in the phylum Porifera. They include 76.2% of all species of sponges with nearly 8,800 species worldwide (World Porifera Database). They are sponges with a soft body that covers a hard, often massive skeleton made of calcium carbonate, either aragonite or calcite. They are predominantly leuconoid in structure. Their "skeletons" are made of spicules consisting of fibers of the protein spongin, the mineral silica, or both. Where spicules of silica are present, they have a different shape from those in the otherwise similar glass sponges. Some species, in particular from the Antarctic, obtain the silica for spicule building from the ingestion of siliceous diatoms. The many diverse orders in this class include all of the large sponges. Most are marine dwellers, but one order (Spongillida) live in freshwater environments. Some species are brightly colored, with great variety in body shape; the largest species are over ac ...

Sycon Ciliatum
''Sycon ciliatum'' is a species of calcareous sponge belonging to the family Sycettidae. Description This small purse sponge grows singly or in small groups from a single holdfast. It is up to five centimetres long, fairly stiff, greyish-white and spindle-shaped. The osculum at the tip is fringed with fine spicules.Barrett, J. & C. M. Yonge (1958) ''Collins Pocket Guide to the Sea Shore''. Collins, London p41. The surface of the sponge appears furry from its covering of fine papillae. The skeleton consists of a tangential layer of triactines and another of tetractines. This species can be distinguished from the rather similar ''Sycon raphanus'' by the fact that the choanocyte chambers are not fused but are free from each other. Distribution and habitat ''Sycon ciliatum'' is common along the coasts of Europe and occurs on the eastern fringes of the Atlantic Ocean from Scandinavia south to Portugal. It is found low down on the shore and in the neritic zone The neritic zone ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The American Museum Journal (c1900-(1918)) (18161026511)
''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archai ...

Leucosolenia Variabilis
''Leucosolenia'' is a genus of calcareous sponges belonging to the family Leucosoleniidae. Species of this genus usually appear as groups of curved vases, up to 2 cm long, each ending in an osculum. The overall shape is sometimes likened to a tiny bunch of bananas. They are most often observed in tide pools, clustered around the base of seaweeds or on rocks, and occur in a variety of colours, usually rather pale. Its canal system is of asconoid type. The colony consists of few simple vase-like, cylindrical individuals each terminating in an osculum and united at their bases by irregular horizontal tubes. Leucosolenia reproduces both asexually and sexually. asexual reproduction by budding and sexual reproduction takes place by formation of gametes, i.e., ova and sperms. Lecosolenia is hermaphrodite, because both the gametes are formed in the body of same individual. Sponges are mostly asymmetrical, but Leucosolenia is symmetrical.

Leucosolenia Botryoides
The orange pipe sponge, sometimes referred to as the orange pipe calcerous sponge or ''Leucosolenia botryoides'', is a soft, white sponge with a tubular branching structure. The name is derived from the Greek word, "botrys", which means "cluster of grapes", relating to the branched structure of the sponge. It was originally found and named ''Spongia botryoides'' and given the common name "grape sponge" by researchers John Ellis and Daniel Charles Solander in 1786 before it was discovered to be a part of the genus ''Leucosolenia'' and changed to the orange pipe sponge. In Ellis and Solander's discovery, they described the sponge as "tender and branched as in bunches" where the "bunches are hollow." It is considered an asconoid sponge because it has no definitive shape. Distribution ''Leucosolenia botryoides'' is found within the North Atlantic Ocean, more commonly on the coasts of Britain and Ireland. It also can be found from the North of Norway to the Mediterranean Coast. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
