I hope they don't accidentally drain Lake Nicaragua! That would be an unprecedented disaster. The price of fish would be rock bottom for a week.
Lake Nicaragua, despite being a freshwater lake, has sawfish
, and sharks
Initially, scientists thought the sharks in the lake belonged to an endemic
species, the Lake Nicaragua Shark (Carcharhinus nicaraguensis
). In 1961, following comparisons of specimens
, the Lake Nicaragua Shark was synonymized
with the widespread Bull shark
a species also known for entering freshwater elsewhere around the world.
It had been presumed that the sharks were trapped within the lake, but this was found to be incorrect in the late 1960s, when it was discovered that they were able to jump along the rapids of the San Juan River
(which connects Lake Nicaragua and the Caribbean Sea
), almost like salmon
As evidence of these movements, bull sharks tagged inside the lake have later been caught in the open ocean
(and vice versa), with some taking as little as 7–11 days to complete the journey.
Running rapids with Bull Sharks, where would that fall in the whitewater rating system?
