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).
Ctenophora is a genus of true crane flies. The species are large (about 20 mm long, with 25-mm wingspans), shiny black craneflies with large yellow, orange, or red markings to mimic wasps. Males have comb-like antennae. The larvae are saproxylic. The species are confined to old deciduous forests, orchards, and other habitats with continuity of ...
Beroe abyssicola is a pelagic ctenophore species that inhabits the North Pacific. [2] Like other Beroida, B. abyssicola has a very different body plan from other Ctenophores, namely the lack of any tentacles in any life stage. [2]
A beroid ctenophore with mouth gaping at left. Beroidae is a family of ctenophores or comb jellies more commonly referred to as the beroids.It is the only known family within the monotypic order Beroida and the class Nuda.
Pleurobrachia bachei is a member of the phylum Ctenophora and is commonly referred to as the Pacific sea gooseberry. These comb jellies are often mistaken for medusoid Cnidaria , but lack stinging cells .
Ctenophora species are found in decaying wood or sodden logs. Nephrotoma and Tipula larvae are found in dry soils of pasturelands, lawns, and steppe. Tipuloidea larvae are also found in rich organic earth and mud, in wet spots in woods where the humus is saturated, in leaf litter or mud, decaying plant materials, or fruits in various stages of ...
Mertensia ovum, also known as the Arctic comb jelly or sea nut, is a cydippid comb jelly or ctenophore first described as Beroe ovum by Johan Christian Fabricius in 1780. It is the only species in the genus Mertensia.
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. In some species, the primary tentacles are reduced and they have smaller, secondary tentacles.
