Did you know that 4000 metres bellow the ocean there are chemosynthetic bacteria that are specifically evolved to digest the wood of trees that have grown on land?
The wood on the sea floor can come from trees that fall into lakes and end up in the ocean, or wooden ships that have sunken. (Called 'Wood-falls')
The reason why deep marine organisms are able to digest wood despite never seeing the light of day, let alone a plant - since plants are unable to grow in the deep ocean because of a lack of sunlight - is because the ocean is so isolated and scarce of food that when a new food source is suddenly available, organisms rapidly evolve to be able to eat it.
This is called 'Adaptive Radiation', and can also occur on isolated islands.
The number one rule of cursed boat voyages is, "no matter how cursed the boat is, do not dive from it." There was no way to survive this from the beginning, but now you will see that truth with your own eyes, and no one will believe you.
Osedax, also known as boneworms, zombie worms or 'the bone-eating snot flower', is a type of marine polychaete worm that like to use their plant-like roots to bore into the bones of whale carcasses.
They don't have a mouth or a stomach so they technically don't eat bones directly. Instead they will dessolve the bone with acid and rely chemosynthetic bacteria to digest the lipid in the bone and convert it into nutritients for the boneworm to eat and in return the bacteria get food and protection from predetors.
