The great hammerhead swims in a side-to-side motion to compromise the blind spot directly in front of them, giving them 360 degree vision. All along the underside of their "hammer" (known as a cephalofoil) are electrosensory organs that are able to detect electric signals.

1. Diverse Species: There are over 500 known species of sharks, ranging in size from small, harmless ones to large, fearsome predators.
2. Ancient Predators: Sharks have been around for a very long time. Fossil evidence suggests that they have existed for more than 450 million years, making them older than dinosaurs.
3. Cartilaginous Skeleton: Sharks have skeletons made of cartilage, a flexible and lightweight material, as opposed to bones. This adaptation helps them in buoyancy and agility.
4. Constant Tooth Regeneration: Sharks have multiple rows of teeth, and they continuously grow and replace them throughout their lives. A single shark can produce thousands of teeth in its lifetime.
5. Sensitive Electrosensory Organs: Sharks have specialized electroreceptors called Ampullae of Lorenzini, which detect weak electric fields generated by prey. This unique sense helps them locate prey, even in darkness or murky waters.
6. Variety of Diets: Sharks are opportunistic feeders and have diverse diets. While some species primarily feed on fish, others consume seals, whales, plankton, or even detritus.
7. Top Predators: Many sharks are apex predators, meaning they are at the top of the marine food chain and play a crucial role in maintaining the balance of marine ecosystems.
8. Different Reproduction Methods: Sharks reproduce using various methods, including live birth (viviparity), laying eggs (oviparity), and giving birth to live young from eggs that hatch inside the female (ovoviviparity).
9. Incredible Speed: Some shark species, like the shortfin mako shark, can swim at incredible speeds, reaching up to 60 miles per hour (96 kilometers per hour), making them one of the fastest fish in the ocean.
10. Conservation Challenges: Sharks face threats from habitat loss, overfishing, pollution, and climate change. Conservation efforts are essential to protect these fascinating creatures and maintain a healthy marine ecosystem.

1. Size Variation: Sharks vary greatly in size. The smallest shark is the dwarf lanternshark, which grows only about 6 to 8 inches (15 to 20 centimeters) long, while the largest is the whale shark, reaching lengths of up to 40 feet (12 meters).
2. No Bones in Fins: Shark fins do not have bones; instead, they consist of cartilage. The dorsal fin, which often appears menacing, helps stabilize the shark while swimming.
3. Wide Distribution: Sharks can be found in almost all ocean habitats, from coastal areas to the deep sea. Some species, like the Greenland shark, inhabit extremely cold waters, while others, like the great white shark, prefer warmer regions.
4. Sense of Smell: Sharks have an incredibly keen sense of smell and can detect even tiny amounts of blood in the water. Their sense of smell is vital for locating prey and navigating their surroundings.
5. Long Lifespan: Some shark species have impressively long lifespans. For instance, the spiny dogfish shark can live for more than a century, making it one of the longest-living vertebrates.
6. Camouflage and Colors: Sharks often have a countershading coloration, darker on top and lighter on the bottom, which helps them blend into the ocean when viewed from different angles. This provides them with a form of natural camouflage.
7. Migratory Behavior: Many shark species are migratory and travel vast distances in search of food, warmer waters, or breeding grounds. For instance, the great white shark is known for its extensive migrations.
8. Sensitive Hearing: Sharks have a highly developed sense of hearing and can detect low-frequency sounds, such as the distress calls of injured prey or the movements of other animals in the water.
9. Ancient Survivors: Sharks have survived several mass extinctions throughout Earth's history, showcasing their remarkable adaptability and resilience as a group of animals.
10. Role in Ecosystems: Sharks play a crucial role in maintaining the health and balance of marine ecosystems by controlling prey populations and removing sick or weak individuals, which helps to keep marine food webs in check.
