Tvärminne Zoological Station Open House 16/09/2017 – See you there!

The unsuspected life of our waters

Oceans and seas cover 71% of the Earth’s surface, but do you know exactly the wealth contained in this environment?

Of course, you’ll say to me that plants, crustaceans, fishes, marine mammals, etc. can be found and you would be right. But did you know that they are also a vast number of tiny organisms, which represent 98% of the oceans’ biomass (meaning that visible animals represent only 2%). Some are so small you could fit thousands of them in a single teaspoon.

These organisms are called plankton. This term, derived from the Greek word “planktos”, which quite literally means a “drifter”. It is consisted of tiny animals (zooplankton) and tiny plants (phytoplankton) which evolved since more 3 billion of years….
