Field Frame Friday: Cat Call via Crab Claw?
“Hey there, wanna check out my burrow?” Fiddler crabs (genus: Uca) have sexual dimorphism, meaning that males and females have different characteristics aside from their sexual organs.

Field Notes: Research in the time of COVID-19
COVID19 has been a tough pill to swallow for everyone, from teachers, to parents, to everyday employees.

Field Frame Friday: Incoming sea gull! Take (algae) cover!
Sea urchins, including this purple sea urchin (Strongylocentrotus purpuratus) will use their tiny tube feet to grab and cover themselves in pieces of algae, small rocks or shells.
