What is comb jelly in biology?
Ctenophores are free-swimming, transparent, jelly-like, soft-bodied marine animals with biradial symmetry, comb-like ciliary plates for locomotion, and the lasso cells, but they lack nematocysts. They’re also referred to as sea walnuts or comb jellies.
What class is a jellyfish in?
True jellyfishesMoon jelly / ClassThe Scyphozoa are an exclusively marine class of the phylum Cnidaria, referred to as the true jellyfish.
The class name Scyphozoa comes from the Greek word skyphos, denoting a kind of drinking cup and alluding to the cup shape of the organism.
Scyphozoans have existed from the earliest Cambrian to the present. Wikipedia
Why are ctenophores called comb jellies Class 11?
Solution : The body of ctenophores bears eight external rows of cliated comb plates which help in the locomotion. Moreover they have a jelly-like appearance. Presence of comb-plates and jelly-like appearance gives the name comb-jellies.
Why are comb jellies not classified with jellyfish?
Many comb jellies have a single pair of tentacles (often each tentacle is branched, giving the illusion of many tentacles) that they use like fishing lines to catch prey. They are armed with sticky cells (colloblasts) and unlike jellyfish, the tentacles of comb jellies don’t sting.
What are comb jellies made of?
Comb jellies have transparent, jelly-like bodies with bright, iridescent color bands, which are made up of tiny hairs called combs. The bands divide the body into eight symmetrical parts. Sea walnuts have a colorless, walnut-shaped body, with two of their body lobes longer than the rest.
Are comb jellies jellyfish?
The comb jelly is a marine invertebrate that swims by beating rows of cilia that resemble combs. Some species have rounded bodies and tentacles like jellyfish, but comb jellies and jellyfish belong to two separate phyla. Jellyfish are cnidarians, while comb jellies belong to the phylum ctenophora.
What genus is jellyfish?
Chrysaora, genus of marine jellyfish of the class Scyphozoa (phylum Cnidaria) that is found in all temperate and tropical seas around the world.
Is a jellyfish a fish or a mammal?
But despite their name, jellyfish aren’t actually fish—they’re invertebrates, or animals with no backbones. Jellyfish have tiny stinging cells in their tentacles to stun or paralyze their prey before they eat them. Inside their bell-shaped body is an opening that is its mouth.
What are comb plates Class 11?
A locomotor organ consisting of a row of strong cilia whose bases are fused are called Comb plates. These are found in ‘Pleurobrachia’.

What is a comb jelly?
The comb jelly is a marine invertebrate that swims by beating rows of cilia that resemble combs. Some species have rounded bodies and tentacles like jellyfish, but comb jellies and jellyfish belong to two separate phyla.
Are comb jellies the sister group to all other animals?
^ Pisani, Davide; Pett, Walker; Dohrmann, Martin; Feuda, Roberto; Rota-Stabelli, Omar; Philippe, Hervé; Lartillot, Nicolas; Wörheide, Gert (15 December 2015). “Genomic data do not support comb jellies as the sister group to all other animals”.
How many types of cells do comb jellies have?
The comb jellies have more than 80 different cell types, exceeding the numbers from other groups like placozoans, sponges, cnidarians, and some deep-branching bilaterians.
Where do comb jellies live?
They live in the ocean and in brackish bays, marshes, and estuaries. Except for one genus that is partially parasitic, comb jellies are carnivores. They prey on other ctenophores and on zooplankton, including small crustaceans, fish larvae, and mollusk larvae. They employ a wide range of strategies to catch prey.
