anthozoan การใช้

• As it has polyp morphology, it is an anthozoan.
• The conulariids were originally thought to be anthozoan cnidarians.
• Some anthozoans can also reproduce asexually through budding.
• These snails are specialist feeders, feeding exclusively on anthozoans by boring into them.
• The polyps resemble the closely related Cnidaria anthozoan ( sea anemones and corals ) polyps.
• The phylogeny of Anthozoans is not clearly understood and a number of different models have been proposed.
• However, the lack of septa or other features diagnostic of anthozoans led researchers to abandon this hypothesis.
• "' Anthozoan Mountain "'is a mountain in the Slate Range of Alberta, Canada.
• Tube-dwelling anemones or cerianthids look very similar to sea anemones, but belong to an entirely different subclass of anthozoans.
• Named in 1925, fossilized anthozoans ( i . e . coral ) are found in the Devonian limestone of the mountain.
• Anthozoan larvae either have large yolks or are capable of feeding on plankton, and some already have endosymbiotic algae that help to feed them.
• Like other anthozoans, sea pens reproduce by co-ordinating a release of sperm and eggs into the water column; this may occur seasonally or throughout the year.
• The state's Pennsylvanian marine life included brachiopods, pelecypods, gastropods, cephalopods, anthozoans ( corals and their relatives ), echinoids, bryozoans, and crustaceans.
• The planula forms either from the fertilized egg of a medusa, as is the case in scyphozoans and some hydrozoans, or from a polyp, as in the case of anthozoans.
• "' Tube-dwelling anemones "'or "'ceriantharians "'look very similar to sea anemones but belong to an entirely different subclass of anthozoans.
• ""'Corynactis annulata " "', the strawberry anemone, is a bright pink colonial anthozoan similar in body form to sea anemones and scleractinian stony corals.
• Fossils of cnidarians that do not build calcareous sponges than these are to other sponges, and that anthozoans are the evolutionary " aunts " or " sisters " of other cnidarians, and the most closely related to bilaterians.
• Phylum Cnidaria ( Coelenterata )-true jellyfish, box jellyfish ( contains some of the most lethal of all venomous animals ), hydrozoans ( includes colony " jellyfish " such as Physalia or Portuguese Man O'War ), anthozoans ( including coral ).
• The "'strawberry anemone "'( " Actinia fragacea " ) is an Anthozoan of the order Actiniaria, a sea anemone, that occurs from Norway to Africa, including adjacent islands ( Azores, Canary Islands and Cape Verde ) and the Mediterranean.
• Depending on the species, the planula either metamorphoses directly into a free-swimming, miniature version of the adult form ( such as many open-ocean scyphozoans ), or navigates through the water until it reaches a hard substrate ( many may prefer specific substrates ) where it anchors and grows into a polyp ( including all anthozoans with a planula stage, many coastal scyphozoans, and some hydrozoans ).
