ctenophores

These features make ctenophores capable of increasing their populations very quickly.

Little is known about how ctenophores get rid of waste products produced by the cells.

For a phylum with relatively few species, ctenophores have a wide range of body plans.

Most ctenophores that live near the surface are mostly colorless and almost transparent.

For this reason their lifespan is not known, but ctenophores begin to reproduce at an early age.

Unlike other groups of ctenophores put them to continue their movement almost exclusively comb ribs.

No ctenophores have been found in fresh water.

Ctenophores are the most basal known type of animals.

In favorable circumstances, ctenophores can eat ten times their own weight in a day.

They also appear to have had internal organ-like structures unlike anything found in living ctenophores.

The fragile makeup of ctenophores makes research into their way of life extremely difficult.

Eurhamphaeidae is a family of ctenophores, it contains the following species:

Colloblasts are a cell type found in ctenophores.

Many species of the jellyfish-like ctenophores have two tentacles, while some have none.

At least two textbooks base their descriptions of ctenophores on the cydippid Pleurobrachia.

They generally feed on zooplankton, ctenophores, other jellies, and sometimes crustaceans.

Nuda is a class of ctenophores or comb jellies.

Nudans feed on free swimming animals with soft bodies, primarily from other ctenophores, certainly larger than they themselves can be.

The Beroe population underwent an initial explosion, until the numbers of both ctenophores stabilized.

Ctenophores may be abundant during the summer months in some coastal locations, but in other places they are uncommon and difficult to find.

He published over 200 scientific articles on marine animals such as chaetognaths, ctenophores, and tunicates.

However, both cnidarians and ctenophores have a type of muscle that, in more complex animals, arises from the middle cell layer.

It feeds on jellyfish, ctenophores and other soft-bodied planktonic animals.

Ctenophores also resemble cnidarians in having a decentralized nerve net rather than a brain.

He also suggested that the last common ancestor of modern ctenophores was either cydippid-like or beroid-like.
