What the Fish? Episode 12: A Fish in Shining Armor

A Fish Can Be Encased in Armor?

Although they vary in size, morphology, and type (e.g., plates, scutes), many fishes have evolved thick armor-like scales that help protect them from their aquatic environment and potential predators. Many fishes that live in and around the bed of aquatic environments utilize armor to protect their bodies from loosing scales as they burrow and scrape along rough substrates and potentially rocky or jagged environments, such as catfishes and poachers. Other armored fishes may sacrifice mobility for a tank-like body that makes them nearly inedible to nearby predators. For example, the aptly named boxfishes have scales are hexagonal in shape and result in an armor that looks like a bee's honeycomb. The body armor of fishes are so effective that various scientists and researchers have been investigating the morphological properties of fish scales, such as those in bichirs, to aid with the development of stronger body armor for humans!
