People, it’s time I drop some science on you and tell you about Siphonophores.
These crazy animals are an order of “colonial jellyfish” in the class Hydrozoa. Colonial, as in their bodies, though they appear to be one large orgamism, are actually constructed of many miniscule individual organisms… kind of like if each of our cells were independent organisms, for example. Most of ya’ll will know about the Portuguese Man O’ War already, or maybe have seen one, with its crazy inflatable-looking head/bell and its reputation for being a scuba-diver-entangling, murderin’ douchebag, but I’ll bet less of you are familiar with the crazy and creepy (read: cuddly + adorable) Praya dubia, also known as the "Giant Siphonophore." It’s not only one of the largest invertebrates in the world, but one of the longest ANIMALS (although technically it’s a whole lot of not-very-long individual animals linked together…) in the world. It’s bioluminescent, and its sting has been known to occasionally kill the crap out of an adult human male, and often results in paralysis.
