Why Sally Lightfoot Crabs Bubble
Sally Lightfoot crabs can spend huge amounts of time out of the water, but they still breathe using gills. To keep those gills working, they retain and circulate water around the gill chambers. The bubbles and foam around their mouthparts appear to be linked to that movement of water and air while they’re on the rocks. ________________________________________________________________________________ Planning a trip to the Galápagos Islands? 🏝️ Paul McFarling is a Galápagos guide and tour organiser with over 30 years of experience helping travellers explore the islands, wildlife, landscapes, and natural history of this extraordinary destination.
