The Galapagos has many amazing animals. Many have adapted to the environment. They have gotten smaller, bigger, more curious, and many more things. After Charles Darwin visited the islands in 1835, he came up with his theory of natural selection by noticing the unique adaptations many animals in the Galapagos had made over millions of years.
The Galapagos lea lion is called the Galapagos sea lion instead of just a sea lion because it has adapted to the environment of the Galapagos. They are most common on the island of San Cristobal and mostly eat sardines. They have adapted to be tamer because they have no enemies in the islands. They are also smaller, and more curious than sea lions on the mainland.
The marine iguana has adapted to the environment of the Galapagos by learning to spit out the salt that they ingest. They also have black skin to absorb more heat and to hide in the black volcanic rocks, have a flat tail to help them swim, and have sharp teeth to scrape the algae off the rocks to eat. They are most common on the island of Isabella.
The sea turtle has adapted to have flippers to swim which is why they are called sea turtles and not just turtles, and they can regulate body temperature faster that any other animal in the Galapagos. They are most common on the island of Santa Cruz and eat sea algae (algae under the sea), sea lettuce, and yellow fish.
