| These anemone eat small crustaceans, plankton and various tidepool animals that venture into the range of their stinging tentacles. |
| Visibility is affected by the plankton levels and thermoclines that refract the light so that an otherwise perfect image can get a woolly edge. |
| The expedition also found rings of plankton organisms that measured 10 km wide. |
| No plankton means no basking sharks or manta rays but it also means exceedingly good visibility. |
| Their cavernous mouths are used to gather up small fish and plankton in the same manner as baleen whales, hence the name. |
| The whale shark, the biggest fish on earth, is a plankton feeder and harmless to divers. |
