Amphiporus Adriaticus
''Amphiporus'' is a genus of nemerteans belonging to the family Amphiporidae. The genus has cosmopolitan distribution In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats.

Nemertea
Nemertea is a phylum of animals also known as ribbon worms or proboscis worms, consisting of 1300 known species. Most ribbon worms are very slim, usually only a few millimeters wide, although a few have relatively short but wide bodies. Many have patterns of yellow, orange, red and green coloration. The foregut, stomach and intestine run a little below the midline of the body, the anus is at the tip of the tail, and the mouth is under the front. A little above the gut is the rhynchocoel, a cavity which mostly runs above the midline and ends a little short of the rear of the body. All species have a proboscis which lies in the rhynchocoel when inactive but everts to emerge just above the mouth to capture the animal's prey with venom. A highly extensible muscle in the back of the rhynchocoel pulls the proboscis in when an attack ends. A few species with stubby bodies filter feed and have suckers at the front and back ends, with which they attach to a host. The brain is a rin ...

Cosmopolitan Distribution
In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The extreme opposite of a cosmopolitan species is an endemic one, being found only in a single geographical location. Qualification The caveat “in appropriate habitat” is used to qualify the term "cosmopolitan distribution", excluding in most instances polar regions, extreme altitudes, oceans, deserts, or small, isolated islands. For example, the housefly is highly cosmopolitan, yet is neither oceanic nor polar in its distribution. Related terms and concepts The term pandemism also is in use, but not all authors are consistent in the sense in which they use the term; some speak of pandemism mainly in referring to diseases and pandemics, and some as a term intermediate between endemism and cosmopolitanism, in effect regarding pandemism as ...

Amphiporus Lactifloreus
''Amphiporus lactifloreus'' is a species of ribbon worm in the phylum Nemertea. It is found on the lower shore, under stones, in shingle and amongst the fronds of seaweed. Distribution This worm is found round the coasts of north west Europe, the Mediterranean Sea, the Gulf of Maine and Cobscook Bay. It is common round the coasts of Britain and Ireland. Description Like other ribbon worms, ''A. lactifloreus'' is not divided into segments but is smooth and contractile. It is up to eight centimetres long with a head slightly broader than the body. The eyes are in four groups, two rows on either side of the front of the head and two more central clusters further back. There is a proboscis which can be extended forward from an opening above the mouth and which can be as long as the body and it is armed with a needle-like stylet. The neck is slightly constricted. The body is rounded above and flattened below and has a flattened tail with a rounded end. The general colour is whitish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
