caption: The image shows a small crab sitting atop a pile of mud, with a wooden stick in the background. The crab appears to be a brachyuran, a type of crab native to the Galapagos Islands. Its shell is a light brown color and its legs are a darker brown. Its antennae are long and thin, and its eyes are small and black. Its claws are gripping the mud as it looks around, ready to defend itself.
