I explored the Galapagos Islands on a tour in the winter of 2023. The mostly unpopulated islands were home to endemic birds, sealions, crabs, turtles and iguanas, who seemed unfazed by the people stopping to photograph them. Marine iguanas in the Galapagos are the only lizards in the world who can live and forage at sea. Normally black in colour, the males change to brighter colours during mating season when they compete for the females. The colours vary by island, as each island has its own sub-species. These two iguanas on San Cristobel, where their mating colours are red and black, battled for a very long time, although I wouldn’t describe the fight as “fierce”. You can see their deadly sharp claws and teeth, but when they battled, they only used their heads to butt up against one another and try to push the other away to assert dominance. This particular battle was won by the larger iguana on the left.
