Exploring in a Mangrove Lagoon

Location: Isla San Jose, San Franciscito Island, Sea of Cortez, Baja California, Mexico

Comments: We are anchored up in a beautiful bay with a crescent white beach and 500-foot high barren desert hills. This morning we went exploring in a mangrove lagoon at Isla San Jose. We ventured inside for over a mile and saw amazing upside-down jellyfish and tiny oysters in the mangroves. We also saw osprey, egrets, ibises and herons. We then steamed over to the protected bay at the south side of the small island of San Franciscito where some of our guests went beach walking (note from Mike – there are great puka shells on this beach!) and hiking to the top of the hill where there was a beautiful panoramic view. On the north end of the island, there is a salt flat where local fishing families come to gather salt used to process the sharks that they handline for.

On our dives there were jawfish that spat out unwanted debris knocked into their vertical tunnels. We also saw a pair of mating electric eels with the male biting and forcing the female on to her back. One of the visiting biologists was quite thrilled to be able to photograph an8-inch synaptic sea cucumber.
