Detailed explanation-1: -Bioluminescence is used by living things to hunt prey, defend against predators, find mates, and execute other vital activities. Some species luminesce to confuse attackers. Many species of squid, for instance, flash to startle predators, such as fish.

Detailed explanation-2: -While the functions of bioluminescence are not known for all animals, typically bioluminescence is used to warn or evade predators), to lure or detect prey, and for communication between members of the same species.

Detailed explanation-3: -Bioluminescence is found in many marine organisms: bacteria, algae, jellyfish, worms, crustaceans, sea stars, fish, and sharks to name just a few.

Detailed explanation-4: -The luminescence emitted by the caterpillar probably attracts feeders propagating and dispersing both nematode and bacteria. Therefore, similarly to the marine bacteria, the bioluminescence in terrestrial bacteria could be used for propagation and dispersion of the species.
