Giant blue spot MudSkipper
among the most fascinating species in these environments. One notable mudskipper is the Blue-spotted Mudskipper (Boleophthalmus boddarti), which stands out due to its conspicuous nature. During low tide, it can be easily observed on exposed mudflats, while at high tide, it retreats to its burrow, remaining hidden.
Growing up to approximately 20 cm in length, the Blue-spotted Mudskipper displays a striking appearance. It boasts bold patterns, including diagonal rows of blue spots along its flanks, accompanied by scattered spots on its cheeks. Dark bands are commonly seen on its flanks, and its eyes are notably large and bulging.
In certain areas, a similar and closely related species called Boleophthalmus pectinirostris, known as the 'Great Blue-spotted Mudskipper,' may coexist with the Blue-spotted Mudskipper.
These mudskippers are highly territorial, leading to frequent skirmishes between neighboring males. During such encounters, both males raise their dorsal fins as a threat, revealing the visible soft fin spines on the anterior dorsal fin. Additionally, males raise their dorsal fins and perform leaping displays to attract females. Once a female is enticed, the male escorts her to his burrow for mating.
Observations suggest that Blue-spotted Mudskippers have a diverse diet, consuming both plant material and small invertebrates.
The Blue-spotted Mudskipper is widely distributed in coastal Southeast Asia, extending from India in the west to regions including Indochina, Borneo, and New Guinea in the east. It is locally abundant in certain parts of Peninsular Malaysia and can also be found in Singapore.
