Answer 2

The property of a living organism to emit light is well marked as pluerobrachia,ctenoplana,beroe

Explanation:

Bioluminescence is a trait that live organisms have that allows them to emit light, and living species that have this property are known as bioluminescent.

Aurelia,physalia,gorgonia:

• Any of several jellylike marine organisms of the order Siphonophora (class Hydrozoa, phylum Cnidaria) known for their colony bodies, floating habit, and powerful sting (genus Physalia).  One of the most well-known siphonophore is the man-of-war.

Pluerobrachia,ctenoplana,beroe:

• Pleurobrachia is a common Ctenophora genus. Sea gooseberry is the popular name for this plant, which belongs to the Hormiphora genus.

Octopus,squid,cuttle fish:

• Cuttlefish, often known as cuttles, are marine mollusks belonging to the Sepiida order. They are members of the Cephalopoda class, which includes squid, octopuses, and nautiluses. Cuttlefish have a special internal shell called the cuttlebone that helps them manage their buoyancy.

Pluerobrachia,ctenoplana,euplectella​:

• Ctenoplana is a comb jelly genus and the sole genus in the Ctenoplanidae family. It is made up of the following species: Ctenoplana agnae Ctenoplana bengalensis Gnanamuthu and Nair.
