Another invasive species in Great Lakes

The invasive spiny water flea likes to dine on the Daphnia flea. The problem is that the Daphnia flea eats algae. So as the Daphnia disappears, the algae grows....

This little flea — and its huge appetite — could ruin the Great Lakes

It sounds like this is one of those "The sky is falling, the sky is falling...." things.


As I recall they said the same thing when alewives first appeared in the Great Lakes. Then they introduced the salmon to eat the alewives. We all know what the end result of that turned out to be.

We have cane toads, ugly warty large amphibians that reproduce faster than rabbits. They were introduced to control some pest in sugar cane fields. Anything that eats one dies of poisoning. They are all over the top half of the country. Fortunately some native animals are learning not to eat them. An ecological disaster.

And you've got crocs! Don't forget the crocs! Do crocs like saltwater?

Sorry to hear about your frogs!
