Because, they want to catch their prey or they want to lie down.
Whilst crocodiles seem to sleep a lot - do not be fooled - as very often they only appear to be sleeping.
They sleep intermittently during the day & night, but without entering the R.E.M. state (which in humans is a deep, dreamlike sleep where the eyes appear to move randomly & rapidly - hence 'Rapid Eye Movement').
Instead, crocs are wired to wake up at the slightest disturbance - they'll be aware of you before you get close enough catch them asleep!
Crocodiles are nocturnal animals, but they sleep in the day too. Because they are cold-blooded reptiles, they need the heat of the sun to power their bodies & accelerate their metabolism.
Crocodiles use the water to conceal themselves in order to ambush their prey. A large crocodile can bring down a full-grown zebra or wildebeest by ambushing it from the water as it is drinking from the edge of a lake or river. Crocodiles use land primarily to bask in the sun. Crocodiles are the greatest solar panels and batteries which take up to half of their energy requirements from the sun and the warmth of the soil. Though being large, a huge crocodile can survive on just one or two kilograms of meat a week, because they can gain energy directly from the sun. Moreover, they are known for their great fasting abilities by using the energy of the sun. When a crocodile is in the water, it is usually floating like a log, with only its eyes, nostrils, and a small portion of its back visible above the water. In this way it can breath while spending a good portion of the day in the water.
Crocodiles lie concealed in the water for long periods of time, because they want to lower their preys guard down so it could easily attack them.
So they can protect themselves from any predators!
