Flagfin Prawn Goby

Mahidolia mystacina, the Flagfin Prawn Goby, is a species of fish in the Gobiidae family.[1][2]

Description

Mahidol mystacina,the Flagfin Prawn Goby or the Flagfin Shrimp Goby or Mahidol Smiling Goby fins have both rays and spines. The dorsal fin has 7 spines and 10 soft rays. The anal fin has a single spine and 9 soft rays. Its head has blue or brown spots, while its body has 5-6 dark irregular crossbars.[3] Males have an elongate first dorsal fin and elongate jaws.[4]

Mahidol mystacina (Mahidol Smiling Goby) reaches 8 centimeters (3.1 in) in length, unsexed;[5]

It uses the burrow of a mottled brown alpheid shrimp with two or more short white saddles or spots.[6]

Range and habitat

This fish inhabits reefs in brackish and marine conditions, and silty coastal bays and estuaries.[5][7] and freshwater tidal zone habitats[8] It roams coastal sand and mud habitats from shallow estuaries to moderate depths on slopes.[6]

Mahidol mystacina (Mahidol Smiling Goby) was discovered in 1932 in Laemsing, Chantaburi. This goby also has a notable history, and name point to an immediate connection with Mahidol university. Mahidol mystacina (Mahidol Smiling Goby) was first recorded by Dr. Huge McCormick Smith, who gave it the scientific name Mahidol mystacina in acknowledgement of Admiral of the Fleet H.R.H. Prince Mahidol of Songkla.[9]

It prefers depths of 5–20 meters (16–66 ft),[4] in tropical waters, from 32°N to 20°S.

Specifically, it has been sighted on the muddy bottom at the base of the reef at Toguan Bay, Guam and from East Africa south to Delagoa Bay, Mozambique.[3] and east to the Society Islands, north to southern Japan (?), south to northern Australia and Samoa.
