The focus of our trip was to photograph the giant mantas (Manta birostris) at San Benedicto Island in the Revillagigedo Archipelago. These are the largest mantas in the world and can be more than 20 feet (6 meters) across and weigh up to 3,500 pounds (1600 kilograms). The dive site called “the Boiler” is a cleaning station for these mantas where fish remove parasites from their bodies. Consequently, this site provides the best opportunities to see and photograph these gentle giants.
The Revillagigedo Archipelago lies approximately 390 kilometers (240 miles) off the coast of Cabo San Lucas in Mexico. These Pacific islands are more commonly referred to as the Socorro Islands. Aboard the Southern Sport, we dove 3 of the 4 islands (Roca Partida, San Benedicto, and Socorro).
A color variant from the more common black and white manta is an all black or nearly all black manta. It is not a different species of Manta birostris. However, it is exciting when one showed up as it looks so different.
San Benedicto is the island for the giant mantas. They are used to divers and show no fear of people. They swim It seems a bit surreal, even a few weeks after our encounter with them, to have had huge mantas swim within a few meters of us.
Our time in the Dutch island of Bonaire in the Lesser Antilles is quickly coming to an end. Our passion is shark photography but this trip was focussed on learning macro photography – you know, the really little stuff. It started off with frustration but slowly produced some good results. These shrimp range in size from 1/4 inch (2-3mm) to about 1 inch (25mm) and some are very difficult to see, especially the transparent ones. Most of the time they are tucked away inside a sponge or an anemone giving few good photo opportunities. As we discovered, perseverance and a bit of good luck are both needed!
What do you do if you are an octopus out during the day and a diver with a camera spots you? First, you keep still and use camouflage hoping nobody can spot you, but when that fails you need to move. This octopus tried a number of tactics from trying to blend in, making a run for it, to puffing up to what I assume is to make itself look bigger. Here is a picture sequence that lasted less than a minute until it found a hole to retreat into. Safety at last!
In South Africa we were supposed to see tiger sharks but they eluded us. In Mozambique we were supposed to see tiger sharks but once again we didn’t see any. Finding a specific shark species around the world is hardly guaranteed as these are wild animals that swim the oceans. However, we were told that if you want to see tiger sharks then you need to go to the world famous “Tiger Beach” to have the highest probability of seeing them. So here we are and finally we have seen tiger sharks!
Tiger sharks are big sharks. They are generally between 10-14 feet in length and weigh between 850- 1400 pounds. We encountered 8 different tiger sharks and two were in the 14 foot range. Being a few feet from them makes you realize just how big they are and how insignificant you are. Truly amazing creatures and a privilege to share the ocean with them!
Tiger sharks are intelligent and it is important to maintain eye contact with them. As long as they knew that you were watching them they would keep back about 10 feet or more. But take your eyes off them and they will get close and personal with you. They had this habit of trying to sneak up from behind so we needed to constantly be looking over our shoulders for them. A few times we had to bump them off with our cameras as they got a little too friendly. Perhaps not for most people, but it is very cool and surreal to be face to face with a 1400 pound tiger shark! You can’t help wonder what they are thinking as they swim by and stare you down.
Chiba Peninsula in Japan is home to numerous varieties of shark. Banded Houndsharks, seen in the video of our last post, are the most numerous in the location where we are diving. We have seen hundreds on most of our dives. Big Fish Expeditions has organized this trip and the local dive company we are diving with is Ito Diving Service Bommie (known as Bommies) and is owned by Kan Shiota. Kan has been indispensable assisting us on every dive. Here Kan is giving the dive briefing along with Kenji Ichimura. Kenji has been part of our group from the beginning and has acted as chauffeur, dive guide, and most important, our interpreter. Meals and menus would have been a challenge without him so thanks Kenji!
The dive boat behind us is just a short 5 minute ride to the dive site. The gear after the dive is ready to go back to the shop. Amazing what you can store in these tiny pickup trucks!
Of course the highlight of the trip are the Banded Houndsharks. There are literally hundreds of these beautiful sharks at this site. Although typically shy, they will come near you, if you stay in one place. Tricia, as you can see is making some new friends.
However, their generally shy and cautious nature can change in a moment when food is around. There can be a hundred in a feeding frenzy all jostling for position. It is a bit surreal to swim through them when this is going on but they are only interested in the food, not divers.
In amongst the Banded Houndsharks are curious & often pushy Red Stingrays who we felt a number of times brushing against our heads. It is interesting to see the vibrant yellow markings on the underside of their body. As Larry swims off to locate some more sharks I captured this picture.
