‘Rayichapalu’ has been officially declared as one of the rarest species of fish in the world by the researchers from the Marine Living Resources Department of Andhra University. The fish is a regular catch for fishermen in Visakhapatnam, Andhra Pradesh. It is a colourful fish which is around 97mm in length and lives near the reefs. The researchers stated that this fish has a unique colour pattern with spectacular diamond shaped bands. Reportedly, it is the only fifth fish in this category of size. Now, the tiny colourful fish will have the scientific name ‘Pseudathias Vizagensis’, after the city where it was first discovered.
