This is a Painted ghost crab, or ocypode gaudichaudii, with a feather. (No, it’s not his.) They’re a common species found on Pacific beaches from El Salvador all the way to Chile, and on the Galapagos Islands. They’re fun to watch, particularly in early evening as they scurry about, often in large numbers, before sunset. They’re very fast, which is presumably where their name came from. As you approach, they vanish quickly into their deep burrows with nary a trace.
They’re fascinating little creatures; I spent about an hour observing and photographing them yesterday and the day before. More pics forthcoming.
