We hit the most westerly island this morning to see the famous marine iguanas. The salt-sneezing dragons were there in their thousands. They camouflage in with the volcanic rocks so well it really was a miracle none of us trod on one at some point.

The first real disappointment of the trip came on the snorkelling trip afterwards - not one of the thousands of the beasts decided it was hungry and so we didn't see any in the water at all. Small comfort came from a couple that decided to take the plunge as we were in the panga headed back to the boat.

That afternoon we headed to Vincente Roca Point back on Isabela Island for a spot of snorkelling (yes, again!). Further disappointment was provided by the few marine iguanas here, however this was more than made up for by the sighting of a large Eagle Ray (over a metre) and three Sunfish (Mola Mola). Look them up, they are pretty special, although very shy despite their size. We saw them briefly before they headed to the relative safety of the deep. It was pretty funny, you could just make them out hovering below us at a depth of about 10m, looking up wishing us away. Bless em.

We also encountered the other species of sea lion, the misnamed Fur Seal. Not nearly so inquisitive or playful.

Early evening the boat's captain hosted a (brief) cocktail party to celebrate crossing the equator as we headed round the top of Isabela. Luckily, the three GPS devices on the bridge showed us hitting zero degrees latitude (or whatever) at three slightly different times and so chances to take photos were abundant. Modern technology huh!
