Nekton

Real World Example

Imagine trying to walk through a crowded mall during a big sale, where everyone is moving in different directions, and you're trying to navigate your own path to your favorite store. This situation is similar to nekton, marine organisms that actively swim and navigate through ocean currents, much like you maneuvering through a bustling crowd. Just as you exert effort and choose your direction amidst the chaos, nekton, such as fish and squid, actively swim and steer themselves through the ocean, unlike plankton that drift with the current, similar to how some people just go with the flow in the mall.
