Smallest vertebrate found

Scientists found the world’s smallest fish, toothless, scaleless, colorless (except for its black eyes/head). The fish is only about 7.9mm (just over a 1/4 of an inch) long.

Correction: 7.9mm is 0.31 of an inch. Also, someone actually found a smaller fish of 6.2mm short!! He was not recognized because his discovery was published at a lesser-known periodical. Hooray for Dr.I-forget-your-name.

Researchers have found the smallest known fish on record in the peat swamps of the Indonesian island of Sumatra.
Individuals of the Paedocypris genus can be just 7.9mm long at maturity, scientists write in a journal published by the UK's Royal Society.
But they warn long-term prospects for the fish are poor, because of rapid destruction of Indonesian peat swamps.[...]
Widespread forest destruction, drainage of the peat swamps for palm oil plantations and persistent fires are destroying their habitat.

Geesh! More to ponder about.

Furthermore, Donat Agosti argues that publications describing new species should be made freely available so scientists in developing countries can access them, nontheless. I agree.
