Animal Adaptaions

Sea lions in the Galapagos are very curious and unafraid of humans.

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 sea 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.

I hope that you liked this little introduction to some of ways animals can adapt to various conditions

Marine iguanas are very different from their mainland ancestors.
They have developed flat tails to help them swim.
Sea lions in the Galapagos are not afraid of people so you can get very close to them.
They are mammals and are fed milk from their mothers.
Marine iguanas have long sharp claws to help them cling to rocks.
Sea turtles spend their whole lives in the water, except when they come ashore to lay eggs. This the track one turtle left in the sand.

About Nancy Sathre-Vogel

After 21 years as a classroom teacher, Nancy Sathre-Vogel finally woke up and realized that life was too short to spend it all with other people's kids. She and her husband quit their jobs and, together with their twin sons, climbed aboard bicycles to see the world. They enjoyed four years cycling as a family - three of them riding from Alaska to Argentina and one exploring the USA and Mexico. Now they are back in Idaho, putting down roots, enjoying life at home, and living a different type of adventure. It's a fairly sure bet that you'll find her either writing on her computer or creating fantastical pieces with the beads she's collected all over the world.
