The Weird and Wonderful World of Worms

Animals with long, skinny bodies are often called “worms,” but there are many kinds of worms—even in the ocean. Annelids (segmented worms) include garden earthworms, but their ocean relatives come in many colors, shapes, and sizes. Some are so small that they live between grains of sand, while others can be longer than a human and eat fish! Marine worms are essential to the ocean food web, as both predators and prey. They help create homes for plants and animals by burrowing and building tubes in ocean sediments. Scientists are still discovering new worm species, and there are still many mysteries about how worms eat, why they live in the places they do, and what roles they play in ocean ecosystems. Worms are a fascinating and important part of ocean communities. More here.
