One of the the ocean's most bizarre animals; the beaded sea cucumber

The beaded sea cucumber is one of the most bizarre animals in the ocean. They resemble giant worms more than they do sea cucumbers. When stretched out, they can reach a length of more than one meter (3 feet).
Beaded sea cucumbers move along the ocean floor, extending their 15 feeding tentacles in front of them. The feathery appendages collect their food and pull it into their mouth opening. in the center of the tentacles. They consume algae, aquatic invertebrates like plankton, and waste particles that are found near the bottom. They are omnivores. Sea cucumbers are like mini ocean janitors that clean and filter the waste and debris out of the water.
Beaded sea cucumbers have no internal respiratory system. They have no feet or appendages capable of locomotion. They contract and expand muscles on the body wall, moving forward through these actions.
Beaded sea cucumbers come in many different shapes and sizes. With their unusual movement and alien looking tentacles, the beaded sea cucumber looks like a creature from another world.
