📚 Quick Study Guide

• 🌊 Gills: 🐟 Many aquatic animals, like fish, have gills to extract oxygen from water.
• 🐾 Webbed Feet/Flippers: 🦆 Ducks and seals have webbed feet or flippers to help them swim efficiently.
• 🐳 Blubber: 🧊 Whales and seals have a thick layer of blubber (fat) to keep them warm in cold water.
• 🚀 Streamlined Body: ➡️ The sleek shape of many aquatic animals reduces water resistance, allowing them to swim faster.
• 👁️ Special Eyes: 🐡 Some fish have eyes adapted to see clearly underwater, even in murky conditions.
• 🛡️ Scales/Waterproof Skin: 💧 Scales on fish and waterproof skin on amphibians help protect them and prevent water absorption.
• 👃 Closing Nostrils: 🔒 Some aquatic mammals can close their nostrils to prevent water from entering when they dive.
