Countershading. This was a new word for me.
Almost all sharks are grayish with a darker top and lighter underside. This is called countershading. Imagine attempting to find places to hide or be inconspicuous in the open ocean. Countershading is works like camouflage, for both predators and prey alike.
The Great Hammerhead is an apex or top predator- it is known for feeding on other sharks, rays and skates, especially stingrays. Countershading benefits the Great Hammerhead in hunting and feeding. When it is viewed from above, the Great Hammerhead darker's back blends in with the ocean bottom underneath. When viewed from below, hammerhead's lighter belly blends in with the lighter sky above.
5% of the profits from these products go to Threatened & Endangered Species.
THREATENED TEXAS SERIES: Each palette & threatened species is unique. I have sampled colors from images of actual Texas Threatened Species: The Great Hammerhead (Sphyrna mokarran) to create this original works.
