Sycon ciliatum is a species of calcareous sponge belonging to the family Sycettidae.
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. [2] 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. [3]
Sycon ciliatum is common along the coasts of Europe and occurs on the eastern fringes of the Atlantic Ocean from Scandinavia south to Portugal. [3] It is found low down on the shore and in the neritic zone, amongst seaweed, under stones or in rock pools in areas without strong wave action. [2]
Sponges, the members of the phylum Porifera, are a basal animal clade as a sister of the diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells.
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups.
The Cottidae are a family of fish in the superfamily Cottoidea, the sculpins. It is the largest sculpin family, with about 275 species in 70 genera. They are referred to simply as cottids to avoid confusion with sculpins of other families.
Halichondria panicea, commonly known as the breadcrumb sponge, is a species of sea sponge belonging to the family Halichondriidae. This is an abundant sponge of coastal areas of the North Atlantic and the Mediterranean Sea ranging from the intertidal zone to a recorded depth of over 550 m. It is also found in the intertidal zone of the coast of the northern part of the North Island of New Zealand. It is very tolerant of a wide range of coastal habitats, including strong currents, high salinity and exposure to powerful wave action. Its only requirement is a rocky substrate which can include small cobbles.
Sycon is a genus of calcareous sponges belonging to the family Sycettidae. These sponges are small, growing up to 7.5 cm and having length from 2.5 to7.5, and are tube-shaped and often white to cream in colour. They are known to aquarium hobbyists as "Pineapple" or "Q-Tip" sponges, and are frequent "hitchhikers" accidentally brought in.
Fabulina fabula, the bean-like tellin, is a species of marine bivalve mollusc in the family Tellinidae. It is found off the coasts of northwest Europe, where it lives buried in sandy sediments.
Tellina tenuis, the thin tellin, is a species of marine bivalve mollusc in the family Tellinidae. It is found off the coasts of northwest Europe and in the Mediterranean Sea, where it lives buried in sandy sediments.
Sycon raphanus is a species of marine invertebrate, a calcareous sponge belonging to the family Sycettidae. The name derives from the Greek, "raphanus", meaning radish, and presumably refers to the sponge's shape.
Terpios fugax is a species of sea sponge belonging to the family Suberitidae. It is found on rocky shores on both sides of the North Atlantic. This species forms small, thin patches on rocks and would be inconspicuous if it weren't for its colour, a startlingly vivid blue.
Ophlitaspongia papilla is a species of demosponge belonging to the family Microcionidae. It is found along north-eastern Atlantic coastlines. This is a red sponge which forms thin, smooth encrusting patches, up to 5 cm across, with regularly spaced oscula.
Pachymatisma johnstonia is a species of sponge belonging to the family Geodiidae. A species of the north-eastern Atlantic coasts, this is a usually grey encrusting sponge with large prominent oscula and a pale yellow interior. The size and form depends largely on the extent of its exposure to waves. In heavily wave-exposed locations, it is usually small and thin but in more sheltered places can grow to over 50 cm across and 15 cm thick.
Sycon faulkneri is a species of calcareous sponge belonging to the family Sycettidae.
Sycon yatsui is a species of calcareous sponge belonging to the family Sycettidae. The scientific name of the species was first published in 1929.
Sycon elegans is a species of calcareous sponges belonging to the family Sycettidae.
The East African coral coast is a marine ecoregion along the eastern coast of Africa. It extends along the coasts of Kenya, Tanzania, and northern Mozambique, from Lamu in Kenya to Angoche in Mozambique. It adjoins the Northern Monsoon Current Coast ecoregion to the north, and the Bight of Sofala/Swamp Coast ecoregion to the south.
Subadyte albanyensis is a scale worm known from the shores of southern Australia from the intertidal to a depth of about 15 m.
Hikurangi Marine Reserve is a marine reserve off the coast of the Kaikoura District, in the Canterbury Region of New Zealand's South Island. It is the largest and deepest marine reserve in New Zealand.
Parininihi Marine Reserve is a marine reserve administered by the Department of Conservation, covering 1,800 hectares in the North Taranaki Bight. It is located offshore of the west coast of New Zealand's North Island, north-east of New Plymouth.
