Beware of Sea Tomatoes

Arctic lakes are not known for their cute and cuddly organisms. But to be fair, they must endure crazy extremes. During the summer they are blasted with 24 hours a day of ultraviolet radiation, and during the winter they endure months of icy blackness, and low levels of life-sustaining nutrients all around.

And yet, some life seems to thrive in this environment. Take for example, the sea tomato. Sea tomatoes are round, plumn and look adorable. However, they are actually colonies of toxin-producing cyanobacteria. And they are piling up on the bottom of Greenland’s lakes. Although sea tomatoes are not uncommon in general, the sheer size and abundance of these particular pile ups are unusual.
