Usually, when it comes to invasive species, the narrative surrounding them is predominantly negative. But hidden in that murky bias are interesting flip-sides. It just depends
how the story’s spun.

As part of my FresH2O Connection project I’ve been gradually exploring freshwater ecosystems, getting to know the inhabitants as intimately as I can. It’s a long, slow process! But I discovered to my delight that zebra mussels (invasive here in the UK), inadvertently provide shelter, camouflage, and food for resident amphipods.

I found this family of three nestled amongst a colony of the much maligned mussels. The larger crustacean is male, measuring about 8mm. Watching the smaller female interact with her mate was fascinating. She appeared to be communicating using her antenna. Haven’t yet cracked the code of their language!

When bonded with a favoured mate, males will protect her against rival suitors, going so far as to carry her around as they move from place to place. Junior is tucked up in bed (over on the far right-hand side) and is absolutely tiny.
