Q. How did American Indians cut their hair?
A. Women generally let their hair grow. They kept it glossy with bear grease. Men cut their hair with sharpened flint. But they had another way of getting rid of their hair. Sometimes they pulled it out, especially around the edge of the hairline. To do this, they used mussel shells. They sharpened the two sides into points - the hinge was provided by nature. The men would use the shells for removing hair from their face as well, so the skin would be smooth for painting.
Q. Are seals aggressive?
A. Seals can be aggressive when they are threatened by an animal or human. They show aggression by growling, snorting and biting. Fighting among most seals is rare. In some species, males will fight during the mating season, and females may be aggressive toward each other or intruders when they are with a pup.
Q. Why do kangaroos hold their babies in their pouches?
A. The pouch has the food source for the baby kangaroo. Also, when the kangaroo is born it is deaf, blind and without fur. Within about four minutes of birth the baby climbs into the pouch. It finds a teat to get milk and attaches itself to it. The teat swells up and holds the kangaroo in place! This teat will be the exclusive property of that kangaroo, even after others have been born and the baby is big enough to leave the pouch. The baby kangaroo stays in the pouch between 90 and 270 days.
