But there is a creature that is thriving in this conditions, the jellyfish. They can be bigger than a blue whale, survive the pressure of the deepest oceans, shine without wasting heat and feed on anything.
Jellyfish don't have a brain or heart or even senses.But jellyfish have a light sensitive cells that help them know when to feed and hide.With that and other unicelular purposes such as venomous stings jellyfish became the masters of survival without having extreme biological changes like legs or eyes or an specialised skin organ.Now the jellyfish rule the world, and if we don't stop putting our oceans to the edge, we must learn to live with them.
