The Decorator Crab
Oregonia gracilis
tiny decorator crab: "Hello from the Pribilofs!"
For example, this crab wants to be a sponge for Halloween:
see the hairs on his carapace and legs?
that's where he attaches his bling!
This crab wants to be red algae (or maybe a Spartan from 300??):
"Prepare for glory!"
Now, decorator crabs don't just decorate themselves for camouflage Halloween; some of the plants/animals they stick to themselves have toxins or chemical defenses that help protect the crab from predation.
Either way (camo or chemical defense), it's pretty entertaining to watch these guys dress themselves. Greg Albrecht (former snow crab student) recorded this fellow dressing up and shared it before, but it's worth a second view:
Have a Happy Halloween!
