With over 500 species, and fossils dating back over 400 million years, sharks are a diverse group of predatory fish belonging to the class Chondrichthyes, which also includes rays and skates. They are known for their unique adaptations, including multiple rows of sharp teeth, keen senses (especially smell and electroreception), and a streamlined body suited for hunting. Sharks play crucial roles as apex predators in marine ecosystems, helping to regulate the populations of other species and maintain ecological balance. They range from the small, harmless dwarf lantern shark to the enormous, filter-feeding whale shark. Despite their often fearsome reputation, most sharks are not a threat to humans and are vital for the health of the oceans. In turn their numbers are threatened by human behavior such as hunting, over-fishing, habitat damage and pollution.

Bone Clones offers high-quality, finely-detailed casts of several species of sharks, rays and fish that would be of great use in biology, zoology, and paleontology programs.
