What is "stiphodon"

Stiphodon is a genus of freshwater gobies. They inhabit swift, clear streams close to the sea and are found in large parts of Asia and Oceania. Many of the 36 currently recognized species have extremely restricted distributions on single islands or even single streams. These are small gobies with bodies squarish in cross section. A female of S. multisquamus with a standard length of 60.4 mm is the largest Stiphodon individual on record.
