mimicry by using bioluminescent light so the prey cannot properly identify the predator.

There are four types of nematocysts in siphonophore tentilla: heteronemes, haplonemes, desmonemes, and rhopalonemes. Heteronemes are the largest nematocysts and are spines on a shaft close to tubules attached to the center of the siphonophore. Haplonemes have open-tipped tubules with spines, but no distinct shaft. This is the most common nematocyst among siphonophores. Desmonemes do not have spines but instead there are adhesive properties on the
