Saw this work presented at the Cefas student conference. I love it - great example of how to make the absolute best out of what initially looks like a fieldwork disaster (study organism gets eaten…)

I don't know who needs to hear this, but most marine biology research careers do not involve SCUBA diving- which means that, among other things, if you have a medical condition that means you can't SCUBA dive, you don't need to abandon your dream of becoming a marine biologist.
