     It could not have been easy to see the tiny swimmer, but a group of scientists claimed to have discovered

the world's tiniest fish. The little creature was found recently in an Indonesian swamp (沼泽).

     For now, the fish is known as Paedocypris progenetica. It has a transparent, or see-through, body. Its head

doesn't have a skeleton (骨架), leaving its brain vulnerable (脆弱的) to its surroundings. The fish, which is

female (雌性的), can grow to be only 7.9 millimeters or (0.31 inches) long, about the size of a large mosquito

(蚊子).

     Maurice Kottelat, a fish expert from Sweden, led the team of researchers that made the discovery. Kottelat

and his team reported their discovery in the Proceedings of the Royal Society, a British scientific journal.

     "You don't wake up in the morning and think today we will find the smallest fish in the world," said Kottelat

in an interview. He and his team were most excited by the possibility of having discovered the world's smallest

vertebrate. "What's important is finding a complete backbone in a body so small," said Kottelat. All fish, reptiles

(爬行动物), birds, and mammals (including humans) are vertebrates.

     It wasn't long after Kottelat's announcement that another researcher challenged the claim with a discovery

of his own. Fish expert Ted Pietsch, a researcher at the University of Washington, says that he has discovered

a fish that is smaller than Kottelat's discovery.

     According to Pietsch, the male Photocorynus spiniceps is a tiny ocean fish measuring only about a quarter

inch. That would actually make Pietsch's fish the world's smallest vertebrate. Kottelat's would come in at a

close second. When Pietsch got in touch with Kottelat to mention the fish, four of which he keeps in his office-

Kottelat did not argue. He kindly gave the title of "world's smallest vertebrate" over to Pietsch's unique fish.

     "So our little fish is only the smallest freshwater vertebrate," Kottelat wrote. "Now I wait until the next

smallest fish is discovered."
