According to legend, the Sally Lightfoot crab was named after a Caribbean burlesque dancer famous for her fancy footwork. Similarly, these salt water crabs have an uncanny ability to dart, dodge and weave in order to outwit most predators. The key word here is “most.” The stalking skills of this Galápagos heron were superior. This slate gray lava heron with yellow and red rimmed eyes is endemic to the Galápagos. The seabird is about 1.2 feet tall.
