Megabalanus Vinaceus
''Megabalanus'' is a genus of barnacles in the family Balanidae. Members of the genus grow to in length and inhabit the lower intertidal zone. Morphology ''Megabalanus'' is an acorn barnacle, a sessile crustacean that secretes a calcium carbonate shell consisting of five plates. It reaches up to in height . Ecology Like other barnacles, they are suspension feeders, grabbing particulate matter from the water column overhead. ''M. tintinnabulum'' has a worldwide distribution and is commonly found on wave-beaten shores, in the lower intertidal zone. They tend to grow in clusters of around 12 individuals. Other species are more select, such as ''M. californicus'' of tidal habitats in California and the greater North American Pacific Coast. While many barnacles deal with competition for space by organisms such as limpets and mussels by growing many organisms close together in colonies, ''Megabalanus'' responds by rapidly growing to a very large size.

Barnacle
A barnacle is a type of arthropod constituting the subclass Cirripedia in the subphylum Crustacea, and is hence related to crabs and lobsters. Barnacles are exclusively marine, and tend to live in shallow and tidal waters, typically in erosive settings. They are sessile (nonmobile) and most are suspension feeders, but those in infraclass Rhizocephala are highly specialized parasites on crustaceans. They have four nektonic (active swimming) larval stages. Around 1,000 barnacle species are currently known. The name is Latin, meaning "curl-footed". The study of barnacles is called cirripedology. Description Barnacles are encrusters, attaching themselves temporarily to a hard substrate or a symbiont such as a whale ( whale barnacles), a sea snake ('' Platylepas ophiophila''), or another crustacean, like a crab or a lobster (Rhizocephala). The most common among them, "acorn barnacles" ( Sessilia), are sessile where they grow their shells directly onto the substrate. Peduncul ...

Trace Fossil
A trace fossil, also known as an ichnofossil (; from el, ἴχνος ''ikhnos'' "trace, track"), is a fossil record of biological activity but not the preserved remains of the plant or animal itself. Trace fossils contrast with body fossils, which are the fossilized remains of parts of organisms' bodies, usually altered by later chemical activity or mineralization. The study of such trace fossils is ichnology and is the work of ichnologists. Trace fossils may consist of impressions made on or in the substrate by an organism. For example, burrows, borings (bioerosion), urolites (erosion caused by evacuation of liquid wastes), footprints and feeding marks and root cavities may all be trace fossils. The term in its broadest sense also includes the remains of other organic material produced by an organism; for example coprolites (fossilized droppings) or chemical markers (sedimentological structures produced by biological means; for example, the formation of stromatolites).

Megabalanus Coccopoma
''Megabalanus coccopoma'', the titan acorn barnacle, is a tropical species of barnacle first described by Charles Darwin in 1854. Its native range is the Pacific coasts of South and Central America but it is extending its range to other parts of the world. Description The titan acorn barnacle is a large species with calcareous plates forming a steep-sided cone which grows to a height and width of . The plates are smooth and are fused together. They are pink and are separated by narrow purple or white radii and the aperture at the top is small. In the Pacific Ocean this species can be confused with '' Megabalanus californicus'' but that species is a darker colour, has a wider aperture and has wider rays between the plates. Distribution The native range of the titan acorn barnacle is the Pacific coasts of Central and South America from Mazatlán, Mexico to the Ecuador/Peru border. It is found growing on rocks and other hard substrates from the low tide mark down to about . Fossil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Megabalanus Azoricus
''Megabalanus azoricus'', the Azorean barnacle, is a species of large barnacle in the family Balanidae. It is endemic to Macaronesia: the Azores, Madeira, the Canary Islands, and Cape Verde. It is the largest and third most common shallow water barnacle of the Azores, where it is heavily exploited for food and has a high commercial value since the colonization of the islands. It was included in the 100 species for priority management within Macaronesia. It is a thoracopodal filter feeder and the majority are hermaphrodites. It is more abundant in the first on the low intertidal and infralittoral rocky shores. The empty shells of the barnacles are a vital habitat for the blennies '' Parablennius ruber'', '' P. incognitus'' and '' Coryphoblennius galerita'' as they provide shelter and substrata for egg deposition during reproduction. A large number of invertebrate species also use the empty shells. Although present throughout the archipelago, it is more abundant in the eastern isla ...
