Zombie Worms

The deep sea osedax, often known as the zombie worm, drills through whale bones despite having neither mouth nor anus. For anything that lives on land, in the sea, or in the air, that is a very impressive resume. These mysterious worms wait for whale fall, which occurs when a whale dies and then drops to the bottom of the sea, despite not even having a digestive tract, let alone a mouth.

They then get hold of the body. They may dig directly into the bones because to the acid that their body secretes. Once within, symbiotic bacteria carry out an enzyme and fat breakdown process that the worms subsequently consume. Although it is not the simplest method, it serves their needs.

Lastly, keep in mind that the worms you can see are always female. As if that wasn't strange enough. Males remain in the larval stage throughout their whole lives, existing only to fertilize the female's eggs when the time comes. They do this by residing in a slime tube that surrounds the female.
