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 43.FBD, W121 05.CEA
Crocodile Shark
The crocodile shark (Pseudocarcharias kamoharai) is a species of mackerel shark and the only extant member of the family Pseudocarchariidae. A specialized inhabitant of the mesopelagic zone, the crocodile shark can be found worldwide in tropical waters from the surface to a depth of 590 m (1,940 ft). It performs a diel vertical migration, staying below a depth of 200 m (660 ft) during the day and ascending into shallower water at night to feed. The crocodile shark is the smallest living mackerel shark. It can be distinguished by its elongated cigar-shaped body, extremely large eyes, and relatively small fins.
An active-swimming predator of pelagic bony fishes, squid and shrimp, the crocodile shark has a sizable oily liver that allows it to maintain its position in the water column with minimal effort. The size and structure of its eyes suggests that it is adapted for hunting at night. The crocodile shark is aplacental viviparous, with females typically giving birth to litters of four. The fetuses are oophagous, meaning that they feed on undeveloped eggs ovulated for this purpose by their mother. Due to its small size, the crocodile shark poses little danger to humans and is of little commercial importance.
