This week I’m a volunteer at the Glover’s Reef Research Station in Belize. I’m here with a bunch of folks to help out the researchers by counting the local numbers of lionfish and measure sea turtles (both population and sizes). It’s pretty interesting work and leads to some tall tales in the evening.
Or ARE they tall?
After dinner, we were sitting around swapping fish stories. One of the old salts told about seeing a fish that was 10 meters long. That's a big fish, but his buddy claimed HE saw one that was 12 meters long and at least 7 meters across.
Should I believe these stories?
This leads to today’s questions:
- What is the
average size of the world’s largest fish? And what is it? (I to
see data from some original research reports, NOT fish stories and secondhand
reportage. We should get data for both
length and girth.)
- Given that fish are somewhat hard to tell apart, what’s
the current best method for estimating the number of these fish?
- (Extra credit) Can you find (or generate) a map of these fish worldwide? How many do the researchers believe there are?
Enjoy your search while I dive!
