First day at North Minerva Reef

Our first day at North Minerva Reef has been outstanding. For one thing the weather has become calm so we can dive and snorkel on all sides of the reef. We have split off into different activities and among us we have swum with a manta ray and green turtles, seen grey reef, whitetip reef and grey reef sharks, and found some wrecks.

This reef is an atoll with a deep pass, so we have anchored in the lagoon and it will be a very calm night of sleep. At night a few of the crew went for a brief night dive on the outer reef – where the shark numbers abbreviated the dive.

Now that we have moved further south we have noticed a change in the fish fauna. The Tonga fangblenny that was endemic to Tonga is no longer found here. It has been replaced by the canary fangblenny (Meiacanthus oualanensis). Interestingly, the canary fangblenny has until now only been recorded from Fiji. Our find here confirms it has a wider distribution than previously thought.

    Minerva Reefs look and sound fantastic. Are there any Galapagos Sharks there?

    All the best,

    Thankyou for once again sending daily blogs on your trip. As always they are most interesting. I was especially interested in your brief blog on the “exploding” volcano. How “fortunate” that you were in the area at the time. Keep an eye on Raoul to make sure it is behaving!!! Were the wrecks off Minerva Reef identifiable?
