The Killer Whale or ORCA as they are commonly called, inhabits all of the Worldâs oceans, preferring the coastal waters near shore in the cooler regions of the planet. Male Killer Whales are larger then the female of the species and can be distinguished easily by the shape of the whales dorsal fin. The dorsal fin of the male Killer Whale is significantly larger and is shaped more triangular then the femaleâs.
When treating head lice, supplemental measures can be combined with recommended medicine (pharmacologic treatment); however, such additional (non-pharmacologic) measures generally are not required to eliminate a head lice infestation.
Causes. Head lice infect hair on the head. Tiny eggs on the hair look like flakes of dandruff. However, instead of flaking off the scalp, they stay in place. Head lice can live up to 30 days on a human. Their eggs can live for more than 2 weeks. Head lice spread easily, particularly among school children.
