-
I was under the opinion that ctenophores differed from cniderians because of the presence of a third layer; perhaps not a true mesoderm but not diploblastic in the same sense that cniderians are.
Jellyfish lack true Hox genes! - The Panda's Thumb
-
As indicated by its small beak-like mouth, the louvar feeds on small, soft-bodied creatures such as jellyfish and ctenophores.

Invoking a magical dude in the sky - whether that magic dude is Zeus, Odin, YHWH, FSM, the invisible pink unicorn, or even a hyperintelligent giant ctenophore may it bless us with its divine cilia that disappears whenever it is looked at - is certainly a paradigm shift.
Nothing New Under the Sun - The Panda's Thumb
-
An example of instability caused by a change in biodiversity is that of the introduction of the invasive, carnivorous ctenophore Mnemiopsis leidyi (a jellyfish-like animal) in the Black Sea, which caused the rapid loss of 26 major fisheries species and has been implicated (along with other factors) in the continued growth of the oxygen-deprived “dead” zone.

A strange ctenophore, related to comb jellies (aka "sea gooseberries").
Yeah!

It is therefore largely appreciated that the resemblance between ctenophores and cnidarians is superficial and does not reflect a particularly close evolutionary relationship.
-
This ctenophore seems to be exhibiting bioluminescence, but what the “lights” actually represent is reflection or refraction of the photoflood lights from rhythmically beating cilia.

Given the likelihood that the ctenophore lineage is the deepest branch among metazoans, let's have a closer look at the toolkit contained by these creatures to determine if the basic theme of front-loading evolution continues to hold up.
