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. InspectorCacheIt227 got into Shark Week about 4 years ago and we regularly record about 60 hours worth of shows each year on our DVR. 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 41.BFE, W121 08.ADC
Spinner Shark
The spinner shark (Carcharhinus brevipinna) is a species of requiem shark, in the family Carcharhinidae, named for the spinning leaps it makes as a part of its feeding strategy. This species occurs in tropical and warm temperate waters worldwide, except for in the eastern Pacific Ocean. It is found from coastal to offshore habitats to a depth of 100 m (330 ft), though it prefers shallow water. The spinner shark resembles a larger version of the blacktip shark (C. limbatus), with a slender body, long snout, and black-marked fins. This species can be distinguished from the blacktip shark by the first dorsal fin, which has a different shape and is placed further back, and by the black tip on the anal fin (in adults only).
Spinner sharks are swift and gregarious predators that feed on a wide variety of small bony fishes and cephalopods. When feeding on schools of forage fish, they speed vertically through the school while spinning on their axis, erupting from the water at the end. Like other members of its family, the spinner shark is viviparous, with females bearing litters of three to 20 young every other year. The young are born in shallow nursery areas near the coast and are relatively fast-growing. This species is not usually dangerous to humans, but may become belligerent when excited by food.
