Just wow! Amazing photo from #ThomaszWilk of an #endangered thick shelled river mussel #UnioCrassus spurting (nice!) to allow their larvae (glochidia) to find a #fish host

In October 2024, we showed how the mesopredator community has shifted in Finland using long-term snow track indices from 1989-2022. We focused on two of the most common mesopredators: the native red fox and invasive raccoon dog.

Pubished in Scientific Reports.

Aquatic sowbugs were to be expected around a detritus filled part of the wetland, but the big crayfish was a nice surprise!

Did you know... that there are freshwater sponges???

Here's a photo I took of some in a lake in Michigan near me. I love finding them, and telling everybody about them. 🤓
