The calf was found rubbing its head on its mother, jumping backwards over its mother and flipper-to flipper, belly-to flipper and belly-to belly contact was observed. Comparing species' relative intelligence is complicated by differences in sensory apparatus, response modes, and nature of cognition. Tursiops, which translates as "dolphin-like," is derived from the Latin word Tursio for "dolphin" and the Greek suffix –ops for "appearance". They have streamlined bodies and two limbs that are modified into flippers. Dolphins breathe air. Dolphin Location: Ocean.
