The United States Postal Service (USPS) has commemorated the fascinating world of sharks through a series of Sharks Forever stamps. These stamps feature five iconic shark species that inhabit American waters: the mako, thresher, great white, hammerhead, and whale sharks.

  1. Mako Shark:
    • The mako shark (Isurus spp.) is a swift and agile predator found in warm and temperate oceans worldwide. It’s known for its streamlined body, pointed snout, and striking blue coloration. Makos are excellent swimmers and can reach speeds of up to 60 miles per hour (97 km/h) when hunting prey. They primarily feed on fish, squid, and other marine creatures.
  2. Thresher Shark:
    • The thresher shark (Alopias spp.) is recognizable by its exceptionally long tail, which can be as long as its body. Threshers use their tails to stun schools of fish, making them easier to catch. They inhabit both deep and shallow waters and are found in tropical and temperate regions. Their diet includes small fish, squid, and crustaceans.
  3. Great White Shark:
    • The great white shark (Carcharodon carcharias) is perhaps the most iconic and feared shark species. With its massive size, powerful jaws, and serrated teeth, it’s a top predator in the ocean. Great whites are found in coastal and open waters, preying on seals, sea lions, and other marine mammals. Contrary to popular belief, they don’t actively seek out humans as prey.
  4. Hammerhead Shark:
    • The hammerhead shark (Sphyrna spp.) gets its name from its distinctive hammer-shaped head, called a “cephalofoil.” These sharks have excellent vision due to their widely spaced eyes, which provide a panoramic view. Hammerheads are social creatures and often swim in schools. Their diet includes fish, rays, and crustaceans.
  5. Whale Shark:
    • The whale shark (Rhincodon typus) is the largest fish in the world. Despite its enormous size, it’s a gentle filter feeder that primarily consumes plankton, small fish, and other microscopic organisms. Whale sharks have unique spotted patterns on their skin, and they can grow up to 40 feet (12 meters) or more in length. They inhabit warm tropical waters.

Remember, these incredible creatures play vital roles in maintaining the balance of marine ecosystems. Let’s continue to appreciate and protect them! ?❤️
