Can dolphins talk? Maybe they can't talk with words, but they talk with sounds. When a dolphin comes back to its group, the others make sounds to say "Welcome". 1 Scientists are doing research on these sounds. How amazing!
Dolphins swim together in a group called a "school". They travel like good friends. Look! A group of dolphins is swimming fast. 2 That's as fast as a car!
Dolphins are also very clever. They can recognise themselves in a mirror! That's surprising! 3
Sometimes people catch dolphins for aquariums (a zoo for fish). 4 They are looking at themselves in the glass and miss their groups.
5 They save people and are real heroes! They are friendly to humans. We should try our best to protect them. Let's make sure they don't become as dead as a dodo!

Emma’s Blog
Last Sunday, my dad took me to the ocean park. I saw many amazing animals—dolphins, turtles, and colorful fish. But the most interesting animals were the seahorses.
At first, I thought seahorses were boring. They are small and thin. They swim slowly. They just hang onto plants with their tails. I said to Dad, “They are not exciting at all.”
But then we met a worker at the park. Her name was Lisa. She told us many surprising things about seahorses.
“Look carefully,” Lisa said. “That seahorse is carrying babies in his pouch! Seahorse fathers give birth to babies. They are the only animal fathers in the world that have babies.”
I couldn’t believe my eyes! How amazing!
Lisa also told us that seahorses can change color to hide from enemies. They can even move their two eyes in different directions. They don’t get lost because they have a good sense of direction.
But then Lisa’s face looked sad. “Many seahorses are in danger now,” she said. “People pollute the ocean. As a result, their homes are gone. We need to protect them.”
I felt sad too. I wanted to help them. Lisa said scientists are doing research to save seahorses. They are trying their best.
