Shark Facts, Tips, and Other Weird Things About Selachimorpha

By US Harbors.

It’s the last day of “Shark Week” for the 2023 season, but that doesn’t mean there is nothing more to see or learn about these compelling–and sometimes–maligned creatures. As a vital part of the ocean food chain, sharks are vulnerable to all the changes happening in the ocean environment and many of their species are now endangered. We’ve put together a list of great articles to help you learn more about them, including tips on how to stay safe in waters where sharks may be traveling. And if you haven’t read it yet, Ernest Hemingway’s Pulitzer and Nobel prize winning novel–The Old Man and The Sea–is not to be missed! (An audio version narrated by Donald Sutherland is also available.)

“Sharks are a superorder of fish. This superorder is also known by its scientific name Selachimorpha. Like other Chondrichthyes, they have skeletons made of cartilage instead of bone. Cartilage is tough, rubbery material which is less rigid than bone.” Shark. (2023, May 24). Wikipedia. July 27, 2023 from
