On This Day in Weird, January 31...
1930: The research ship Dana captures an apparent
leptocephalus (eel larva, literally "slim head") off Africa's Cape of
Good Hope. Its size astounds examiners, measuring 6 feet 1.5 inches long. The
average leptocephalus for European eels measures three inches and metamorphoses
into an adult roughly one meter long, suggesting to some that the adult form of
what they dub Leptocephalus giganteus might exceed 400 feet in length.
Others dismiss the notion, observing that leptocephali of various species grow
at different rates. The preserved specimen presently resides at Copenhagen
University's Zoological Museum. No other members of its species have been found
to date.
