A HAND Whale Aunties or escorts have been identified in most whale species. Their role seems to range from midwifery to healthcare and babysitting. If a problem arises during delivery, for example, the escort remains to accompany the new mother, driving off unwelcome visitors such as sharks, other whales, and even ships. Aunties also help the newborn baby to the surface for its first breath. Orcas have been known to literally drive themselves onto the beach to attack prey such as seals.
Dolphins have twice as many folds as humans.
Orcas, the so-called 'killer whales,' are actually dolphins and not whales. They can be gentle and trained in captivity. A whale's movement through the water is propelled by the vertical movement of the hind part of its body. Blubber is a fatty tissue consisting of cells filled with oil droplets. It is such an efficient insulator that in the days of the old whaling stations, a delay in working on a dead whale would result in the whale meat being cooked in its blubber envelope, like a garden compost heap.
