With its collection of subcellular organelles that resemble the lens, cornea, iris, and retina, the eyelike structure is startlingly similar to multicellular eyes found in humans and other animals, the researchers say in a study published in Nature.

How many eyes do planktons have?

The larvae of Platynereis are free-swimming plankton. Each has a transparent brain and six small, pigmented eyes which contain rhabdomeric photoreceptors . These enable the larvae to detect and swim towards light sources.

A single-celled marine plankton has evolved a miniature version of an eye to help see its prey better, researchers believe. The tiny creature, which can only be seen under a microscope, it thought to use the complex structure to spot organisms which it can consume.

Can planktons be seen?

Even though they may be ten to 100 times larger than a bacterial cell, you would still need to look through a microscope to see these organisms. Some plankton are big enough to be seen with the naked eye. Try this the next time you visit a pond or lake: scoop up a glass of water and hold it up to the light.

Despite being largely invisible to the naked eye, plankton can be seen from space when they form massive blooms.

Answer: Freshwater phytoplankton, usually rich in green algae, also includes diatoms, blue-green algae, and true flagellates. In the oceans, phytoplankton biomass rises and falls according to multiyear cycles and appears to be sensitive to changes in sea surface temperatures, climate change, and ocean acidification.
