Sharks 🦈: They are predatory, cartilaginous fish (Class Chondrichthyes) with skeletons made of flexible cartilage rather than bone. Distinguished by 5–7 gill slits, rough dermal denticle skin, and multiple rows of replaceable, sharp teeth, they inhabit all oceans. Most possess torpedo-shaped bodies for speed, with sizes ranging from the tiny 22 cm pygmy shark to the 13.7 m whale shark. #shark#viral#fyp

Did you know sharks have zero bones? 🦈✨ Instead of a traditional skeleton, their bodies are made entirely of cartilage. This lightweight structure makes sharks incredibly agile and buoyant, allowing them to glide effortlessly through the water and turn on a dime when hunting or exploring. Cartilage also gives sharks the durability they need to survive in the ocean, helping them thrive for over 400 million years. Every aspect of their bodies, from their fins to their jaws, is perfectly designed
