Dolphins

Friendly and fascinating, dolphins are one of nature's most intelligent animals. They live in families called pods and can make a series of 2,000 high-pitched clicks to locate fish in the water. Despite their beauty and playfulness, dolphins face serious dangers from commercial fishing and human activity. It's vital that people support governmental laws to protect these wonderful creatures.
