As we shark dive around the world we rarely have an opportunity to visit a shark research facility. Our two weeks on Bimini Island allowed us to photograph great hammerhead sharks, bull sharks, nurse sharks, blacknose sharks, Caribbean reef sharks, southern stingrays, and Atlantic spotted dolphins. What a fantastic diversity of big animals around a very small island. We got to see baby lemon sharks and nurse sharks at the Bimini Shark Lab.
The research they do here is invaluable. Sharks are under threat worldwide and research is needed to better understand them and protect their nursing sites. One thing that their research has revealed is that the female lemon shark returns to the same mangrove sites that they were born at to give birth to their pups. Knowing this allows researchers to influence governments to protect these critical environments.
We found it fascinating to go to their holding pen to see the young shark pups that they were doing research on. We photograph the adults in the oceans but never see pups. Young sharks reside in the mangroves skirting the islands for protection in their early years but at some point venture away from these safe zones. The shark pup with the barbels is a nurse shark and the other is a lemon shark. So neat to see such young, small sharks.
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.
