Tiny but mighty creatures
Although it may sound like something out of a horror movie, this monster exists–but don’t worry, they’re not as big as you might think. This creature has bulging eyes, antennae, a pointed mouth, and thousands of tiny teeth. They reproduce quickly, so they usually live in groups of other monsters just like them.
Through a microscope, these are sea parasites. They come in all shapes and sizes but may be impossible to detect with the human eye. But don’t let their size fool you–they can still be dangerous. These creatures enter the fish’s body and feed off of them until they eventually kill the host.
