They say teamwork makes the dream work - and this couldn’t be more true for siphonophores. At first glance, this mesmerizing deep-sea drifter looks like one creature, but it’s actually made up of hundreds, sometimes thousands, of tiny individuals.
Each “individual” in the colony, called a zooid, has its own specialized job: some sting and catch prey, another digests it, another helps the whole colony swim. No two zooids do the same job, even though they are all genetically identical to each other. In fact, they are so specialized that a single zooid couldn’t survive on its own.
Chains of zooids can grow together into a variety of different ways; some long and stringy like glow-in-the-dark Christmas lights, while others look more like jellyfish, such as the infamous, venomous Portuguese man o’war siphonophore. The largest known siphonophore ever discovered stretched 150 feet long - that’s bigger than a blue whale.
So the next time you’re dreading that group project, think of those tiny, microscopic zooids that join together to rival the size of the sea’s largest animal. Talk about teamwork!
