Sea otter are nekton and plankton; they can float and swim.
A sea urchin is classified as benthos. Benthos refers to organisms that live on or near the bottom of a body of water, and sea urchins typically inhabit the ocean floor, often among rocks or coral. In contrast, plankton are free-floating organisms, and nekton are active swimmers.
nekton
benthos - it lives on the sea bed and "swims" occassionally.
Zooplankton (pronounced ZO A PLANKTON) is plankton
Nope. They are nekton because they actively swim and catch their food.
benthos
Oops that definition was for nekton. Sorry! Nekton are any sea animals that live on the ocean floor, from the continental shelf to the abyssal plain. Starfish, coral, sea urchins, and crabs are included.
Dolphins are nekton because they actively swim and catch their food.
a sea cucumber is a benthos because it does not move is just stays on the ocean floor
Plankton aren't turtules and plankton aren't turtles.
Nekton are aquatic organisms that can swim and move independently in water, such as fish, whales, and squid. Benthos are organisms that live on or in the ocean floor, such as sea stars, crabs, and clams. Both groups are important components of marine ecosystems.
No. It is a deep sea fish and not part of the Plankton
