We can find plastic at the bottom of the ocean and on top of Mount Qomolangma （珠穆朗玛峰）. Now it has been found in another place: on the of hermit crabs （寄居蟹）. Hermit crabs live close to the shore and have soft bodies. For protection, they shells to use as their homes. But guess what? Some hermit crabs are now using plastic waste as their shells!
Why do the crabs choose waste over seashells? Scientists are still trying to find the answer. One idea is that there aren't enough shells as sea snail （海螺） populations are falling. What's more, plastic is light and . for crabs to carry. But there is one thing scientists agree on: Plastic pollution is changing the of sea animals.
