Galapagos Land Iguana under an Opuntia Tree growing on Coral Boulders Galapagos Land Iguanas (Conolophus subcristatus) are often found under opuntia trees. El Nino storms greatly reduced the number and size of opuntia trees on these flat islands. The iguana's leathery mouth is so hard that it can chew cactus pads without removing the spines, although iguanas are often seen rubbing the spines off with their mouth or claws.

Most of the rocks here are blocks of coral uplifted from the sea rather than the usual black lava. Here on the low side of the island the white coral has an unusual sheen. The rocks here have been polished by the oil on sea lion's fur as they clamber over them! South Plaza Island.
