…when you accidentally swallow a nasty gulp of salt water… to be honest wasn’t just salt.
Plankton are microscopic organisms that drift on the oceans’ currents. They include organisms such as diatoms, dinoflagillates, krill, and copepods as well as the microscopic larva of crustaceans, sea urchins, and fish. Plankton also include tiny photosynthetic organisms that are so numerous and productive that they are responsible for generating more oxygen than all other plants on Earth combined
1Crab Larva: Less than a quarter of an inch long, this delicate, transparent arthropod has a long way to go before it reaches maturity and yet its various body parts are already recognisable.
2 Cyanobacteria: These coiled filaments are representatives of some of the most primitive life forms on Earth. Among the very first organisms to have evolved, they can photosynthesize.
3 Diatoms: These small, boxy single-celled organisms are a type of algae, encased in a silica cell wall of great beauty. When they die, these tiny cell walls sink to the bottom of the sea, where they may be compacted to form rock.
4 Copepods: The most common zooplankton and may be the most important animals in the oceans, as they form the most abundant source of protein. They are tiny, shrimp-like crustaceans. They form the basic foodstuff of countless fish species. Some scientists believe that, taken together, copepods would form the largest single animal mass on Earth
5 Chaetognaths: These long, translucent organisms are arrow worms, predatory marine animals that form a large constituent part of the plankton. Some can even inject paralytic venom.
6 Fish eggs: Nearly all fish lay eggs, although a few (including some sharks) give birth to live young. But most fish species release huge numbers of fertilised eggs into the open sea, a large percentage of which will be eaten.
7 Marine worm: A multi-segmented polychaete equipped with dozens of tiny, hair-like appendages with which it propels itself through the water.
