Welcome to Shark Week!! Every year since 1988, the Discovery Channel has devoted a week each summer to sharks. What started as an attempt to educate the public that there was more to sharks than just what they saw in Jaws has since become a cultural phenomenon. Last year while watching Shark Week, EmmaBoo227 started to write the names of sharks on log sheets she created and stuck them in a handful of containers we had won at a raffle and the idea for a shark week series was born.
But where to hide a shark week series? In the ocean would be ideal, but not realistic. But we have a body of water nearby. And while the caches can’t really be hidden in the lake, we could make them all puzzles and hide the caches around the lake. So that’s what we did. We hope you enjoy learning a little about some sharks you have probably heard of and learning a little more about some sharks you have probably never heard of.
These hides are all placed around Folsom Lake. Care was taken to avoid poison oak as much as possible, but it is still out there. Also beware off all the other hazards of the lake including, but not limited to, ticks, snakes, other animals, heat and uneven footing.
Cache is located at N38 42.DFA, W121 05.BEC
Frilled Shark
The frilled shark (Chlamydoselachus anguineus) is one of two extant species of shark in the family Chlamydoselachidae, with a wide but patchy distribution in the Atlantic and Pacific Oceans. This species is found over the outer continental shelf and upper continental slope, generally near the bottom, though there is evidence of substantial upward movements. Exhibiting several primitive features, the frilled shark has often been termed a living fossil. It has a dark brown, eel-like body with the dorsal, pelvic, and anal fins placed far back. Its common name comes from the frilly or fringed appearance of its six pairs of gill slits, with the first pair meeting across the throat.
Seldom observed, the frilled shark may capture prey by bending its body and lunging forward like a snake. The long, extremely flexible jaws enable it to swallow prey whole, while its many rows of small, needle-like teeth make it difficult for the prey to escape. It feeds mainly on cephalopods, as well as bony fishes and other sharks. This species is aplacental viviparous: the embryos emerge from their egg capsules inside the mother's uterus, where they survive primarily on yolk. The gestation period may be as long as three and a half years, the longest of any vertebrate. Litter sizes vary from two to fifteen, and there is no distinct breeding season. Frilled sharks are occasional bycatch in commercial fisheries, but have little economic value.
