Our first liveaboard experience was to Guadalupe Island off Mexico in the Pacific Ocean. The sea conditions were rough with waves 7-9 feet and many people were very seasick. The good news is that we handled the conditions quite well and just felt a bit nauseated. It proved to us that we could handle very adverse sea conditions. The 400 km (250 mile) trip started from Ensenada, Mexico and took about 24 hours to cross on the 33 meter (110 foot) vessel called the Sea Escape. Guadalupe Island is a volcanic island and home to some very large great white sharks (Carcharodon carcharias).
The great white shark, also called the white shark, can grow extremely large with some females capable of reaching 6+ meters (20 feet). As the females mature their girth increases considerably for every foot of growth. It was hard to imagine a 1900 kg (4,000 pounds) great white shark swimming a meter or two away from us and we had big expectations. Sadly, the largest shark we experienced was about 4 meters (12-13 feet). Certainly, not a monster female but a very large shark none the less.
Our first experience with great white sharks was in South Africa but the water was not very clear (green water) so it was difficult to get good pictures. As our photographs show, Guadalupe is a great place to photograph these majestic creatures. We will certainly do Guadalupe island again with hopes of photographing a massive female.
Our previous posts on the Revillagigedo Archipelago, also called the Socorro islands, have included the giant mantas(Manta birostris), whitetip reef sharks(Triaenodon obesus), and silky sharks (Carcharhinus falciformis). Although Galapagos sharks (Carcharhinus galapagensis) are fairly common especially at Roca Partida, we did not have any encounters with them there. However, on one dive we did come across a few juveniles at Socorro island and this gave us an opportunity to photograph this species.
Older sharks of all species have very scarred bodies which are simply a result of surviving in a dangerous ocean environment. However, these juvenile Galapagos sharks, which were about a meter (2-3 feet) in length, had skin with very few blemishes. Adult Galapagos sharks can reach 3 meters (9-10 feet) in length.
The silky shark (Carcharhinus falciformis) gets its name from the smooth texture and silky look of its skin especially when it is young. These sharks can grow to 2.5 meters (8 feet) in length and are very abundant in the Revillagigedo Archipelago. Generally referred to as the Socorro Islands, these volcanic islands lie approximately 390 kilometers (240 miles) off the coast of Cabo San Lucas in Mexico.
Although we encountered scalloped hammerheads, tigers, Galapagos, whitetip reef, and silvertip sharks the most numerous were the silky sharks. At dusk, as the sun was setting, a few of us slipped into the water behind the boat in an attempt to photograph these sharks with the sun’s rays penetrating behind them to give a visually stunning look. Thank you to Andy Murch of Big Fish Expeditions for showing us this technique as we are relatively new to underwater photography.
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). The whitetip reef shark (Triaenodon obesus) is common here.
The whitetip reef shark rarely exceeds 1.6 meters (5 feet). It is nocturnal and rests during the day under ledges and caves. At Roca Partida, we observed many groups of whitetip reef sharks congregating in groups of 3 to 15 on the ledges. By approaching them slowly we were able to capture this behavior.
These sharks hunt at night and eat mainly crustaceans like crabs, lobsters, and shrimp as well as bony fishes. They tend to hunt in groups. During the day, it was interesting to observe many large lobsters out in the open just a few feet away from the whitetip reef sharks. Apparently, the lobsters know that they are safe from these sharks during the day.
The purpose of our dive was to photograph Horn sharks and we got lucky on our second dive around Danzante Island in the Loreto Bay National Marine Park, Sea of Cortez, Mexico. Thank you to Juan Carlos Reyes Valerio our dive master for finding these rather reclusive sharks. Although we found 3 different horn sharks, 2 were deep in crevices and they were impossible to photograph. However, it only takes one and this shark was out in the open apparently waiting to be photographed. Horn sharks are not strong swimmers and this shark is trying to tuck as close to the rocks as possible.
This area has more than sharks and we saw 3 different species of ray, two that stayed still long enough for us to photograph. The ocellated electric ray or bullseye electric ray (Diplobatis ommata) can generate a moderate electric charge for self-defence. The bullseye or ocellus on the back is very distinctive and is where it derives its name. It is a small ray reaching about 10 inches (25cm) in length.
The second ray we were able to photograph was the spotted round ray also known as the Cortez round ray (Urobatis maculatus). They have short tails compared to many other rays and reach a length of about 17 inches (45cm). This ray didn’t stick around for very long before it headed to deeper water.
A surprise for us to come across was the banded guitarfish (Zapteryx exasperata). We were not aware that there were a guitarfish species in the Sea of Cortez. This fish can reach up to 4 feet (1.25m) and has both dorsal fins of nearly identical size. Unfortunately, it had its head facing away from us partly going into a crevice.
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.
Strange to be photographing lions and leopards in the Serengeti National Park in Africa one week and then photographing sharks in the Bahamas about a week later! We departed from West Palm Beach, Florida and headed to the famous “Tiger Beach” off of Grand Bahamas Island in hopes of finding tiger sharks. The Dolphin Dream, a 83 foot ocean expedition liveaboard, was our home for a week and we were well looked after by Captain Scott, Gerard, Shane & Heidi. We sailed through the night, cleared customs in the Bahamas in the morning and headed to a spot to do a few checkout dives in the afternoon to make sure our gear was working fine. It wasn’t long before we were taking photos of lemon sharks which commonly inhabit this area. Day 1 was all about lemon sharks.
Sharks are opportunistic feeders and lemon sharks are no exception. They are slowly swimming about searching for food but once it appears they quickly shift gears and the action can get lively. These sharks discovered food in the sand and the competition to get there first is fierce. Notice a second shark below the first one in the second photograph.
Lemon sharks are easy to identify as the first and second dorsal fin (the fins on top of their backs) are almost the same size whereas most other sharks the back dorsal fin is much smaller. These sharks can reach 11 feet in length but are commonly found in the 7 to 10 foot range which are the size that we photographed. Their eyes are a bit smaller than other sharks and they often swim with their mouths partially open.
One of the new photographic techniques we are trying to master is what is called an over-under where you place your camera 1/2 in the water and 1/2 out. This captures the shark in the water and at the same time shows the sky. We tried these as the sun was going down at the end of the day. It gives a very unique and different perspective of these lemon sharks. Not bad photos for our first attempt at “lemon-snaps”! Thanks to Terry Steeley of In The Blue Photography for all his advice about this technique.
