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.
Scientists have found that head lice either do not have a preference or prefer clean hair since they have an easier time laying their eggs and feeding in clean hair. What they also found is that head lice are more common in long hair. Interestingly enough, head lice infestations are also two to four times more common in girls that in boys â perhaps because of the long hair factor. Girls are also known to have more head-to-head-contact than boys.
