Tarantulas give people the creeps because they have large, hairy bodies and legs. While these large spiders can take a painful bite out of a human, a tarantula’s venom has a low toxicity to people. Tarantulas move slowly on their eight hairy legs, but they are accomplished nocturnal predators. Insects are their main prey, but they also target bigger game, including frogs, toads, and mice. Tarantulas are burrowers and typically live in the ground. There are hundreds of tarantula species found in most of the world’s tropical, subtropical, and desert regions. They vary in color and behavior according to their specific environments. A tarantula doesn’t use a web to trap its prey, though it may spin a trip wire to signal an alert when something approaches its burrow. These spiders grab with their legs, inject paralyzing venom, and then bite their prey with their fangs. They also secrete digestive enzymes to liquefy their victims‘ bodies so that they can suck them up through their strawlike mouth openings. Yum! Tarantulas have few natural enemies, except for the parasitic pepsis wasp, which can paralyze a tarantula with its sting and lay its eggs on the spider’s body. When the wasp eggs hatch, the larvae chow down on the still living tarantula. Tarantulas shed their external skeletons in a process called molting. During the process, they also replace internal organs, such as stomach lining, and can even regrow lost legs.

This shark’s unusual name comes from the unusual shape of its head, an amazing piece of anatomy built to maximize the fish’s ability to find its favorite meal: stingrays. A hammerhead shark uses its wide head to trap stingrays by pinning them to the seafloor. The shark’s eye placement, on each end of its very wide head, allows it to scan more area more quickly than other sharks can. The hammerhead also has special sensors across its head that helps it scan for food in the ocean. Living creatures‘ bodies give off electrical signals, which are picked up by sensors on the prowling hammerhead. The shark hunts alone, and can find stingrays that hide under the sand on the seafloor. Hammerheads also eat bony fishes, crabs, squid, lobsters, and other sea creatures. The upper sides of these fish are grayish-brown or olive-green and they have white bellies. They have very impressive triangular, serrated teeth—like the edge of a saw’s blade. Hammerheads‘ mouths are on the underside of their heads. Unlike many fish, hammerheads do not lay eggs. A female gives birth to live young. One litter can range from six to about 50 pups. When a hammerhead pup is born, its head is more rounded than its parents‘. There have been very few recorded attacks on people by the great hammerhead.
