The 100-Foot Sea Critter That Deploys A Net Of Death

Siphonophores are a class of marine animals belonging to the phylum Cnidaria. Although a siphonophore appears to be a single organism, each specimen is actually a colony composed of many individual animals. Most colonies are long (they can grow to 100 feet long), thin, transparent pelagic floaters.
Siphonophores clone themselves thousands of times over into half a dozen different types of specialized cloned bodies, all strung together to work as a team - a very deadly team at that.
