Several variables are used to evaluate an animal's performance. For example, a "probe trial" measures how long the test subject spends in the "target quadrant" (the quadrant with the hidden platform). [12] More elaborate trials alter the location of the hidden platform, or measure distance spent swimming in the pool before reaching the platform ...
Box turtles require an enclosed outdoor location, consistent sun exposure and a varied diet. Without this, a turtle's growth can be stunted and its immune system weakened. Finding box turtles in the wild and taking them as pets, even for a short period, can have detrimental effects. Box turtles want to stay within the area where they were hatched.

Box turtles can be injured by dogs and cats, so special care must be taken to protect them from household pets. Box turtles require an outdoor enclosure (although they can have indoor enclosures when necessary), consistent exposure to light and a varied diet. Without these, a turtle's growth can be stunted and its immune system weakened.
Mata mata turtles use a specific method of seizing their prey. They will move the prey into shallower areas of water, surround the prey, and wave their front legs to prevent them from escaping. Once surrounded, the mata mata turtles will open their mouths and contract their pharynx, causing a rush of water that pushes the prey into their mouth.
Cheloniidae (sea turtles) have found a solution to the problem of tetrapod swimming through the development of their forelimbs into flippers of high-aspect-ratio wing shape, with which they imitate a bird's propulsive mode more accurately than do the eagle-rays themselves.
