Turtles sleep with their eyes closed under or above water. They tend to be cranky if you wake them up though (trust me, I know) If it is the winter you have to watch out to make sure that they don't try to hibernate though. If you keep waking them up and they start to stop eating than they are very likely to die. Winter is the roughest part of a turtle's life in captivity. Keep them warm and have a light so that they never know that winter has come and gone.
they eat frogs smaller turtles insects and smaller animals
They sleep :)
In search of food and mates
yes they sure are :D
Usually a brownish-green.
From my experiance, no, I've even had adult painted turtles kill baby snapping turtles, I reccomend you keep them separate
They either sleep on land or in the water.
well since sea turtles rarely sleep they really dont but if they do they will sleep on a nearby beach
they crawl into their shells and sleep
I have seen, box turtles, red-eared sliders, some kind of map turtle, a snapper and a very large cooter............
Floating turtles tend to sleep with their eyes open. This ability to sleep with their eyes open helps them to stay alert and detect potential threats in their environment even while they are resting.
red bellied turtles sleep on the moist hard rocky shore of fresh water
