Shark

A predatory cartilaginous fish characterized by a streamlined body, typically a tough skin covered in denticles (small, tooth-like scales), powerful jaws, and sharp teeth. Sharks inhabit oceans worldwide, displaying a wide range of sizes, behaviors, and dietary preferences, from filter-feeding giants to swift hunters. They play a crucial role in marine ecosystems as apex predators, regulating prey populations and maintaining biodiversity. Their sensory systems are highly developed, including electroreception to detect prey and keen senses of smell and hearing. Sharks face threats from overfishing, habitat destruction, and climate change, leading to population declines for many species. They are oviparous, viviparous, or ovoviviparous and may attack humans.
