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
Sea otter are nekton and plankton; they can float and swim.
benthos - it lives on the sea bed and "swims" occassionally.
Zooplankton (pronounced ZO A PLANKTON) is plankton
benthos
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
A tube worm is classified as benthos. Benthos refers to organisms that live on or near the seabed, and tube worms typically inhabit deep-sea environments, often attaching themselves to the ocean floor or hydrothermal vents. Unlike nekton, which are swimming organisms, and plankton, which are usually drifting or floating in the water column, tube worms remain anchored to their substrate.
Plankton aren't turtules and plankton aren't turtles.
Nope. They are nekton because they actively swim and catch their food.
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
