Here's a fish story that's almost as bad as tales of the legendary
candirú. The climbing perch (Anabas testudineus) is a small fish that
possesses an organ that allows it to breathe atmospheric oxygen for
several hours at a time. Its musculature also allows the fish to move
terrestrially. (Watch a tidbit of the above video. See those perch
flopping about on dry land? Get that image firmly in your mind, and
apologies in advance.)
These handy evolutionary traits recently resulted in a nightmarish
scenario when 12-year-old Philip Muan of Rumah Endawie Nangka Jela
Engkari, Malaysia got one of these hardy creatures stuck in his throat
for 14 hours. As Star Online explains:
Fish that can survive out of water for 7 hours jumps down boy's
throat, gets stuck there for 14
He removed the hook and tried to bite the head of the
[four-centimeter-long] fish to kill it but it slipped into his mouth
and lodged itself in his throat [...]
It was already 11 PM by the time he arrived [at the hospital] and
the boy was spitting blood. The fish had by then died and a foul smell
emanated from the boy's mouth. The operation to remove the dead fish
took just a few minutes.
This incident happened at 9 AM in the morning, so this poor kid spent
most of his waking day with a confused fish slowly dying in his
throat. If "wiggling fish that can breathe air asphyxiates in your
gullet" isn't a form of obscure underworld torture on display at
Singapore's Haw Paw Villa amusement park, it really deserves to be.
