The animal of the day is the Quagga Mussel. (Did you know: These fingernail sized mussels, along with their zebra mussel relatives are wreaking havoc in the Great Lakes of Michigan.
These guys are a textbook case of showing how delicate a food web is. These mussels eat algae. Alot of algae. And unlike their zebra mussel friends, these guys can live in deep water [not just shorelines and boat hulls like the zebra mussels are limited to].
The result? Alot less algae for plankton to eat, meaning alot less plankton for small fish to eat, meaning alot less small fish for big fish to eat, meaning alot less fish in general. Makes sense.
The big problem is that, we just started to notice the effects, and their population size is still growing exponentially.
Oh, and they also block up pipes,
One of the worst parts about the whole mussel scenario is that while they are edible to humans and fish, they also filter alot of the pollution out of the water, and into their bodies…So eating too much of them can fill you [and the fish they eat] up with toxins. Yay.
