Ctenophora - "Also known as “comb jellies,” ctenophora emit a blue or green light that can only be seen in the dark. They also secrete ink that luminesces most brightly in the smaller bodies of young comb jellies. A rainbow effect is created when light scatters through the distinctive comb-like tentacles of the ctenophore."

Jellyfish come in a huge range of forms, however, their body construction is reasonably similar. The body of an adult jellyfish consists of a bell shaped hood enclosing its internal structure and from which tentacles are suspended. Each tentacle is covered with cells called ‘cnidocytes’ (a type of venomous cell unique to the phylum ‘Cnidaria’), …

Medusa Jellyfish are the major non-polyp form of individuals of the phylum Cnidaria. They are typified as free-swimming marine animals consisting of a gelatinous umbrella-shaped bell and trailing tentacles. The bell can pulsate for locomotion, while stinging tentacles can be used to capture prey.
