The penguins are a hoot.  Quite small but very distinctive.  They are the most fun to watch when they are scooting through the water, especially if there are seals about, but that is too difficult to photograph.

There were many more sea iguanas basking on the rocks.  They have to warm up enough to head back under the cold water to feed on the lichen.  Not a very efficient food source so they have to spend a lot of time feeding.  Once they start to get cold they have to get back out of the water again and onto a sunny rock to warm up while they can still move.  The sea lions like to interrupt this process and grab their tails.  Even once the iguanas have made it to the waters edge there is usually a steep climb over very scratchy lava rock before they can even think about the basking part.

Just round the corner there is a small beach with plenty of shade where the sea lions like to go and rest. 

The difference between a sea lion and a seal is that a sea lion walks on its front flippers whereas a seal scoots along on its front.  There are fur seals in Galapagos and we saw a couple, but sea lions are everywhere.
