Dolphin Classification
Dolphins are classified as Nekton.
Why Nekton?
Nekton are animals that actively swim and move independently through the water column. Dolphins are powerful swimmers with strong tails and fins, allowing them to travel long distances without relying on currents.
Why Not Benthos?
Benthos live on or in the ocean floor. Creatures like crabs, starfish, and sea anemones fit this category. Dolphins, as active swimmers, do not live on the seabed.
