I was a bit afraid of running into banded sea snakes in Indonesia, as they are highly venomous. Supposedly there is enough venom to kill a person in one bite - it's 10x more toxic than rattlesnake venom. However, they have small mouths and therefore it is supposed to be hard to bite humans. I didn't find this encouraging, however. Then, I saw one.
I was on an afternoon snorkel and I saw the snake popping in and out of the coral. They have to go to the surface to breathe, and it was probably about 2-3 feet under the surface. I was THRILLED. The snake was about 2 feet from me, and I had to try hard not to let the current move me too close. I was able to get a few photos and watched as the snake swam under, then past me. I wish I had stayed with this snake even longer - it was one of my favorite finds of the trip. (There was just always so much to see, and one didn't want to get too far from the guide/small group, so you can't stay too, too long at any one find). I fell madly in love, then and there, with sea snakes. They are gorgeous, graceful, beautiful creatures. There is a bright yellow portion near the mouth. I watched this snake swim and it was just mesmerizing. What an awesome creature.
I ended up seeing three of these snakes during the trip, but this was my first and favorite sighting. I no longer fear them and I was always very grateful, and lucky, to find one. I hope I see these again.
