Meet the Ctenophora - series about less known animals
After the successful article devoted to Rotifers, today we will learn more about the Ctenophora (known as the Comb jellies).
Just as the Rotifers, Ctenophora are actually the separate Phylum.
And the Phylum denotes is the level of classification just under the level of the Kingdom (plants, animals, fungi...).
Evolution of Ctenophora
Ctenophora are known even in fossilized form since the Cambrian era (510 Mya).
Today we can find between 100 and 150 species (depending on the sources).
As the intuition tells you, Ctenophora are related to Cnidaria (jellies).
In contrast to Cnidaria, Ctenophora have a different type of muscles (myoepithelial) instead of epitheliomuscular.
What do they do?
As you remember, Rotifera had the life without the stress, because they have only one ganglion.
Cnidarian nervous system is more complex, forming the net.
They are also glowing in the dark thanks to the bioluminescence.
Here is the video of bioluminescent Cnidaria:
Morphology
Morphology of the Ctenophora is fairly simple and similar to Cnidarian.

resteeming this one.. Happy new year !
Thank you and
Eυτυχισμένο το νέο έτος!
You are a multilearner . What can I say...
After many summers in Greece, it comes naturally :) Greek food also tastes better when called the right name and the music becomes even better when you can understand at least 10% of words
You re probably right !
