Physical characteristics
Possesses a somewhat elongated body with a mottled brown or olive coloration and darker vertical bars on the sides. Key features include prominent, high-set bulbous eyes for aerial vision, fleshy pectoral fins used for 'walking' on land, and a dorsal fin with silver spots or lines. Their skin is specialized for cutaneous respiration.
Habitat & distribution
Found in the Indo-Pacific region, specifically in mangrove swamps, salt marshes, and intertidal mudflats. They inhabit the transition zone between water and land, often remaining out of the water for extended periods in high-humidity environments.
Ecological role
Functions as a secondary consumer, feeding on small invertebrates like insects, crabs, and worms. They serve as prey for shorebirds and larger aquatic predators. Listed as 'Least Concern' by the IUCN, though they are highly dependent on healthy mangrove ecosystems.
Similar species
Other Mudskippers in the Periophthalmus genus, such as Periophthalmus kalolo. They are distinguished by the specific arrangement of silver spots on the first dorsal fin and the number of rays in the pelvic fins.
