Daar is duisende seelewe in ons oseane en seë, baie is nog nie ontdek nie, en ander weerspieël alle skakeringe van die volmaakte reënboog. See anemone word die blomme van die see genoem, maar inderwaarheid is dit nie blomme nie. See anemone is beenlose, roofdiere wat familiebande met korale, jellievisse en ander hidrozoa deel. Terwyl die meerderheid anemone hul lewens geanker aan ‘n soliede struktuur spandeer, is ‘n paar spesies vryswemmers.

See anemone is ywerige wesens wat ‘n groot deel van hul lewens spandeer om kos uit die waterkolom te onttrek om te oorleef. ’n Seeanemoon is ’n waterdier wat ongewoon lyk wat aan die Actiniaria-orde behoort. Alhoewel hulle lewende organismes is, is hierdie wesens in werklikheid vernoem na hul ooreenkoms met die aardse anemoonblom. Die blomagtige voorkoms kom van talle rye tentakels wat die mondskyf in ‘n kroonformasie omring, baie soos dié van ‘n sonneblom. Hierdie tentakels kan heeltemal in die liggaamskolom ingetrek word om homself teen roofdiere te beskerm, en ook wanneer dit prooi vang. Die tentakels is bedek met nematosiste, wat gespesialiseerde selle is wat sekere spesies bevat om te help met selfverdediging en jag van prooi.
See anemone
Daar is meer as 1 000 verskillende spesies seeanemone, maar is geneig om soortgelyke eienskappe te hê. Eerstens het hulle drie hoofdele: ‘n pedaalskyf (basis of voet), ‘n silindriese liggaam en tentakels wat uit ‘n sentrale mond kom.
See anemone is kleurvol
Terwyl sommige spesies wel spesifieke geslagte het, is ander spesies hermafrodities en kan hulle voortplant met of sonder ‘n ander anemoon. By seksuele voortplanting word sperm en eiers gelyktydig vrygestel, en die bevrugte eiers sal uiteindelik vestig en ontwikkel in ‘n poliep, die fondament van die anemoon. Maar die ongelooflike anemoon kan ook ongeslagtelik voortplant, deur ‘n “knop” op een van sy tentakels te ontwikkel wat van die ma skei wanneer dit volwasse is, of deur middel van binêre splitsing, waar die anemoon homself eintlik in twee kan verdeel om twee nuwe individue te word , of pedal laceration, waar ‘n klein stukkie afgesny van die voet kan ook regenereer in ‘n nuwe, ten volle funksionele anemoon.
Sea anemones are industrious creatures, spending much of their lives extracting food from the water column to survive. A sea anemone is an unusual-looking aquatic animal that belongs to the Actiniaria order. Although they are living organisms, these creatures were in fact named for their resemblance to the terrestrial anemone flower. The flower-like appearance comes from numerous rows of tentacles that surround the oral disc in a crown formation, much like that of a sunflower. These tentacles can be completely retracted inside the body column to protect itself from predators, and also when it catches prey. The tentacles are covered in nematocysts, which are specialized cells that certain species contain to assist in self defense and hunting prey.
While there are more than 1,000 different species of sea anemones, they tend to have similar characteristics. First, they have three main parts: a pedal disc (base or foot), a cylindrical body, and tentacles coming out of a central mouth.
Perhaps most interesting of all is the anemone’s various methods of multiplying. While some species do have specific sexes, other species are hermaphroditic, and can reproduce with or without another anemone. In sexual reproduction, sperm and eggs are released simultaneously, and the fertilized eggs will eventually settle and develop into a polyp, the foundation of the anemone. But the incredible anemone can also procreate asexually, by developing a “bud” on one of its tentacles that separates from the mother when it is fully mature, or through binary fission, where the anemone can actually split itself in two to become two new individuals, or pedal laceration, where a small piece severed off the foot can also regenerate into a new, fully functional anemone.
