Bull sharks are one of the most common and aggressive types of sharks. Although they mainly inhabit bodies of saltwater, they can tolerate freshwater. Fish biologist Zeb Hogan has found that young bull sharks tend to use freshwater areas as nurseries where they can feed and grow in relative safety from predators.
Despite the prevalence of sharks in Chesapeake Bay, few shark attacks are reported along the Maryland coast. One reason is that Maryland's coastline is relatively short, but the large jellyfish population during the summer also is a factor. Few people choose to venture into the water, preferring to avoid encounters with jellyfish.Learn more about Sharks
Sharks are afraid of dolphins when outnumbered because they like to eat animals that are much smaller than them, including baby dolphins, but adult dolphins will protect their young by trying to kill a shark any time they see one. Dolphins are usually successful at killing the sharks that they find because they attack in groups, ramming their bodies into the shark until it dies.Full Answer >
Sharks do not have a backbone because their skeletal system is made up of a softer cartilage, just like all the other fish that belong to the Chondrichthyes class. The cartilage found in sharks is not as hard as a real bone, but it is strong enough to support their muscular system and the rest of their body.Full Answer >
A shark's size depends on the type of shark that it is, as the great white shark can grow as long as 20 feet, while the dwarf lantern shark only grows as long as 6.3 to 6.8 inches. To determine the size of a shark, a researcher first determines the shark's species, and then looks at the data available for that given shark species.Full Answer >
Adult sharks weigh anywhere from much less than 1 pound to 42,000 pounds or more. The dwarf lantern shark, reaching a maximum length of 8 inches, is the smallest, while the whale shark tops the list at more than 40 feet in length.Full Answer >
