In the summertime -- and at the beach -- there is no more fearsome a nightmare than the appearance of a shark in the surf.
Sharks terrify us because of their strength, power and "alien-ness," but also because they can attack, often fatally, without warning.
In the course of everyday life today, man as a species has few real predators. But go to the ocean, and a predator swims just beneath the glassy surface of the sea...watching and waiting.
Oddly, the sharks of cult-TV history are not always traditional in nature, or even ocean-bound.
Shark aliens (called Karkarodon), similarly, have appeared on The Clone Wars (2008 - 2014).
And on Saturday morning television, a shark knock-off of Scooby Doo had his own show, called Jabberjaw (1976 -1978).
