Bryozoa
Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals) are a phylum of simple, aquatic invertebrate animals, nearly all living in sedentary colonies. Typically about long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeding. Most marine bryozoans live in tropical waters, but a few are found in oceanic trenches and polar waters. The bryozoans are classified as the marine bryozoans (Stenolaemata), freshwater bryozoans (Phylactolaemata), and mostly-marine bryozoans (Gymnolaemata), a few members of which prefer brackish water. 5,869living species are known. At least two genera are solitary (''Aethozooides'' and ''Monobryozoon''); the rest are colonial. The terms Polyzoa and Bryozoa were introduced in 1830 and 1831, respectively. Soon after it was named, another group of animals was discovered whose filtering mechanism looked similar, so it was included in Bryozoa until 1869, when the two groups were no ...

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 ...

Electra Arcuata
Electra (; grc, Ήλέκτρα) is one of the most popular mythological characters in tragedies.Evans (1970), p. 79 She is the main character in two Greek tragedies, '' Electra'' by Sophocles and '' Electra'' by Euripides. She is also the central figure in plays by Aeschylus, Alfieri, Voltaire, Hofmannsthal, and Eugene O'Neill. She is a vengeful soul in '' The Libation Bearers'', the second play of Aeschylus' ''Oresteia'' trilogy. She plans out an attack with her brother to kill their mother, Clytemnestra. In psychology, the Electra complex is named after her. Family Electra's parents were King Agamemnon and Queen Clytemnestra. Her sisters were Iphigeneia and Chrysothemis, and her brother was Orestes. In the ''Iliad'', Homer is understood to be referring to Electra in mentioning "Laodice" as a daughter of Agamemnon. Murder of Agamemnon Electra was absent from Mycenae when her father, King Agamemnon, returned from the Trojan War. When he came back, he brought with him his ...

Electra Pilosa
''Electra pilosa'' is a species of colonial bryozoan in the order Cheilostomatida. It is native to the northeastern and northwestern Atlantic Ocean and is also present in Australia and New Zealand. Description Colonies of ''Electra pilosa'' form broad mats or star-shaped patches on the surface of the fronds of large algae such as ''Laminaria'' and ''Fucus serratus''. The zooids also grows in small patches or tufts on the surface of shells and stones, and encircling the fronds of red algae such as ''Mastocarpus stellatus''. The zooids are packed closely together, are cylindrical and about . Each one has a mineralized exoskeleton with a transparent, membranous oval window. The calcified protective covering bears about nine spines (four to twelve), the central one being much longer than the others, giving the colony a hairy (Latin ''pilosa'') appearance. Distribution ''Electra pilosa'' is native to the northeastern and the northwestern Atlantic Ocean, the Mediterranean Sea, the N ...

Electra Posidoniae
''Electra posidoniae'' is a species of bryozoan in the family Electridae. It is endemic to the Mediterranean Sea, and is commonly known as the Neptune-grass bryozoan because it is exclusively found growing on seagrasses, usually on Neptune grass (''Posidonia oceanica''), but occasionally on eelgrass (''Zostera marina''). Description ''Electra posidoniae'' is a white bryozoan forming encrusting colonies of zooids on the leaves of seagrasses. The colonies consist of irregularly branching ribbons formed from a single layer of zooids, up to four zooids wide, neatly arranged in parallel rows along the length of the leaf blade. The colonies can reach in length; they are poorly calcified which makes the colony flexible and able to bend as the leaf moves in the water. This species could be confused with '' Electra pilosa'', which also grows in the Mediterranean, but that species tends to grow in star-shaped colonies that have a rough or bristly appearance.

Cheilostomatida
Cheilostomatida, also called Cheilostomata, is an order of Bryozoa in the class Gymnolaemata. They are exclusively marine, colonial invertebrate animals. Cheilostome colonies are composed of calcium carbonate and grow on a variety of surfaces, including rocks, shells, seagrass and kelps. The colony shapes range from simple encrusting sheets to erect branching and even unattached forms. As in other bryozoan groups, each colony is composed of a few to thousands of individual polypides. Each individual has a U-shaped gut, and no respiratory, circulatory, or nerve system. Unique among bryozoans, cheilostome polypides are housed in a box-shaped zooids, which do not grow larger once the zooid is mature. The opening through which the polypide protrudes is protected by a calcareous or chitinous lidlike structure, an operculum. Cheilostomes possess avicularia, which have modified the operculum into a range of mandibles (possibly for defense) or hair-like setae (possibly for cleaning). ...
