The things you find in algae

My big herbivory experiment is done, and the summer is coming to a close - classes start in less than two weeks! There's still plenty that needs to get done - yesterday we did a trip down to Connecticut and Rhode Island to collect some algae. Similar to what I was doing at the start of the summer, we are trying to quantify the species composition of algal communities in different locations, where the invader is present.

So I am back to sorting algae out of bags, which is long and somewhat mind-numbing, but there are many happy distractions in the form of little critters hiding out in the algae.

Today is arthropod day...

A little spider crab sitting on the tip of my finger.

Itty bitty little crab - it looks like an Asian Shore Crab, which is also invasive to this region. For scale: it is sitting on a microscope slide.

A very pretty pycnogonid (sea spider) on the same microscope slide.

The great escape

Living and working in a marine lab is always interesting because things like this happen.

I am sitting in the lobby of the building at night, working on my laptop. Out of the corner of my eye, I catch movement in the dark, empty main lab. An escaped green crab scuttles out into the lobby in a small burst of speed, then pauses to see if anyone has noticed.
