- Group: Phronima Amphipods
While the Phronima can be found in most ocean territories except artic waters, they are not exactly referred to as parasites by some. In fact, scientists have often called them parasitoids. This still makes them a parasite, but parasitoids work a bit differently compared to simple parasites. They will often live inside their host, even allowing it to mature into an adult. Yet some might actually connect themselves to their host on the outside of its body. Of course, the Phornima like regular parasites can influence its host’s behavior.
That forces the host to be used exactly as the Phronima chooses, and will get exactly what it wants when it wants it. Once reproduction begins, the female will attack the salps of the water creature it is attached to. The female will use its mouth and claws to begin eating the animal on the inside and hollow out its gelatinous shell. It will then enter the barrel to lay the eggs inside, then propel the barrel through the water as larvae develop. That provides them with food and water on a regular basis as needed. The Phronima can do so much for such a long time to its host, making it one of the most notable body-snatching parasites on the planet.
