Fish are aquatic vertebrates that are typically ectothermic or what we say - cold-blooded. Now, who do you think is the cold-blooded one here?

I read there are 4 till 6 meter these fishes in Po. And they are not from Italy. And they eat everything they find, all autoctone fishes now.

They will eat everything from the lake, I suppose. Then, we better eat them first!
