Cozumel Night Life! September 12, 2012 ~ blueangelscubaschool ~ Leave a comment It has been said that Cozumel’s best night life is underwater… Blue Angel is now offering regularly scheduled night dives on Tuesdays and Thursdays! See sleeping fish, crabs, shrimp, squid and lots of weird and wonderful things. The PADI Night Diver course is also offered; check here for information and send us an email to sign up! octopi are active at night, and they’re awesome! many gastropods, like this True Tulip, are active at night – and beautiful! you will see LOTS of these guys, both the anemone and the crab! If you’re lucky, you will see one of these guys, a beaded sea cucumber. Creepy, right? Email us for information on your Night Diver course, or with any questions!
