Diagrams of Ctenoplana kowalevskii. Ctenoplana is a genus of comb jellies, and the only genus in the family Ctenoplanidae. It comprises the following species: Ctenoplana agnae (Dawydoff, 1929) Ctenoplana bengalensis Gnanamuthu and Nair, 1948 [1] Ctenoplana caulleryi Dawydoff, 1936; Ctenoplana duboscqui Dawydoff, 1929; Ctenoplana korotneffi ...
a Beroe ovata, b unidentified cydippid, c "Tortugas red" cydippid, d Bathocyroe fosteri, e Mnemiopsis leidyi, and f Ocyropsis sp. [17]. Among animal phyla, the ctenophores are more complex than sponges, about as complex as cnidarians (jellyfish, sea anemones, etc.), and less complex than bilaterians (which include almost all other animals).
Pleurobrachia bachei is a selective carnivore and its feeding habits are analogous to other ambush "sit and wait" predators, such as the orb-weaving spider.When searching for prey the Pleurobrachia swims with its oral pole forward to set its tentacles.
Pleurobrachia is a common genus of Ctenophora (an exclusively marine phylum). Along with the genus Hormiphora, [2] it generally has the common name sea gooseberry. It contains the following species: [1] Pleurobrachia arctica Wagner, 1885; Pleurobrachia australis (Benham, 1907) Pleurobrachia bachei L. Agassiz, 1860; Pleurobrachia brunnea Mayer, 1912
Tentaculata is a class of comb jellies, one of two classes in the phylum Ctenophora. [1] [2] The common feature of this class is a pair of long, feathery, contractile tentacles, which can be retracted into specialised ciliated sheaths.
The monophyly of Nuda is widely accepted, due to the complete lack of tentacles, and the presence of macrocilia as a common secondary feature, or synapomorphy. There are approximately 25 species in the family Beroidae, grouped into two genera .
Platyctenida is the only benthic group of organisms in the phylum Ctenophora. Platyctenida are considered to be a phylogenetically young group along with the orders Lobata and Beroida and are believed to have stemmed from an ancestral version of the order Cydippida, after some kind of bottleneck effect in the phylum.
Common names (such as "red fox") are different across languages, whereas the scientific name does not change. In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same ...
