1. Crocodiles - have tough and scaled skin that allows them to camouflage and catch prey in the water
2. Frogs - have developed bodily fluids that secrete poison to prevent predators from attacking them
3. Bats - have developed their echolocation to help them in hunting for food at night time.
4. Coelachants - have maintained their extra fins for sensory motor in the water
