| This may have made it the most easily accessible prey for predators in the nekton, such as fishes. |
| Plants and animals arrive as plankton, nekton, fouling organisms, and benthos. |
| Animals that are strong swimmers and live in open water and middle layers of the water are called nekton. |
| Herbivorous nekton are not very common, although a few nearshore and shallow-water species subsist by grazing on plants. |
| The migrations of plankton and nekton throughout the water column in many parts of the world are well described. |
| On average, collections were made every 3-4 d for phytoplankton and zoo-plankton, 7 d for benthos, and 10-14 d for nekton. |
