Sharks are some of the most remarkable animals on Earth--fast, powerful predators that have survived for millions of years.
This high-interest nonfiction title takes readers beneath the waves to explore how sharks' bodies are built for life in the ocean. Clear, leveled text explains how their flexible cartilage skeletons help them move quickly, how their fins keep them balanced and steady, and how their tooth-like scales reduce drag as they swim.
The book also examines the serious threats sharks face today. Many species are hunted for their fins or caught by accident. Pollution harms their ocean home. People catch too many fish, leaving sharks without enough food. Because sharks grow slowly and have only a few pups at a time, their populations fall quickly when too many are killed.
Real world conservation efforts show how scientists and communities are working to protect sharks through marine reserves, fishing rules, and habitat protection. With dramatic visuals, bite-sized facts, and critical-thinking questions, this title supports comprehension, vocabulary development, and reading confidence.
