Organisms living in the deep ocean must be adapted to survive under extreme pressure, limited light, cold temperatures, and other factors. Organisms living in the deep ocean must survive in a physical environment that is radically different from ocean habitats near the sea surface.
Answer:
They need to adapt to the sea life. You could google this by the way but I'm giving it in my own words unlike the person on top of me.
So,
1. Staying alive and staying in water with right temperature and not too much pressure.
2. Looking to find things to eat.
3. Staying in a place where you won't get killed.
Hope this helps.
