An account of my time spent volunteering on shark research at the Bimini Biological Field Station in Bimini, Bahamas

Tigers

Twice per month, we set 5 longlines around the island. Each line is a quarter mile long, with 15 hooks per line. We put baracuda steaks on the hooks as bait, and check them every 4 hours over a 24-hour period. Typically we catch nurse sharks, blacktips, lemons, and tigers. Until yesterday, I wasn't lucky enough to be on any of the line checks when they pulled up a tiger.

Yesterday afternoon, however, we pulled up a 115cm tiger shark. It was a juvenile, so its markings were very clear. We did a workup on it, but before we released it, it was picture time! While on the boat, I held its dorsal while we did the workup, and then I took its length measurements. Before we let it go, I hopped in the water with my snorkel gear and took several underwater photos of it. It was, in a word, awesome.

About 10 minutes earlier, we followed a 5-ft tiger shark that was circling one of the baited hooks. It hadn't taken the bait, so we followed it and tried to catch it by hand. Grant, the lab manager, stood on the bow with a noose and was going to lasso it by the tail when it came to the surface. Unfortunately, it made a sharp cutback and we lost it in our own wake.

Later that day, when we were bringing the lines in, there was a 213cm tiger on the line. After we did the workup, we released him so that he was held only by his tail rope. At that point, we all jumped in with our masks and snorkels and got some amazing pictures. Unreal.

So 3 tigers in one day. I think that officially made my year!

I've been trying to post a picture of me holding the juvenile tiger shark, but it doesn't want to load on this computer. You'll just have to take my word for it that it was very cool.
