Killer whales

　　Socializing among killer Whales includes a great variety of communication between members of the group. Killer whales can be distinguished by the kinds of underwater communication sounds they produce - squeals and screams. Killer whales have acute hearing and also acute vision both in and out of the water. When resting, whales slow down and at times stop altogether, and usually become very quiet underwater.
