The Researchers discovered two species of goby fish – Hemigobius hoevenii and Mugilogobius tigrinus at the Coringa wildlife sanctuary near Kakinada in Andhra Pradesh.
They had not been recorded in Andhra Pradesh previously.
This discovery is significant as M. tigrinus has been found along the eastern coastline of India for the first time.
Both species belong to a group of fish commonly known as "gobies."
Most gobies found in estuarine areas, especially around mangroves.
Since 1988, extensive studies along the Andhra coast have recorded 615 finfish species, spanning 352 genera and 140 families.
However, goby fish have not been studied as extensively.
