Giant mudskipper
Periophthalmodon schlosseri

Family Gobiidae
updated Oct 2016

Where seen? This large mudskipper is often seen in Sungei Buloh Wetland Reserve and some of our other mangroves, usually in the back mangroves. At low tide, large ones are often seen in or near their 'swimming pool'. At high tide, they may be seen clinging to mangrove tree roots.

Features: 15-27cm long, it is the largest of our mudskippers. It has a black stripe along the side of its body. At night, it may have additional dark bars across the back.

Sometimes mistaken for and the Yellow-spotted mudskipper (Periophthalmodon walailakae) which were long mistaken for juvenile Giant mudskippers. Unlike the Giant mudskipper, the Yellow-spotted mudskipper does not have a broad black band along the body length and lacks the white-bluish, iridescent speckles often seen on the Giant mudskipper's cheeks.

It builds deep burrows in the mud as a nursery for its young. A large pool is usually constructed at the opening of the burrow. During the breeding season, both the male and female may live in and maintain the burrow.

What does it eat? An aggressive hunter, it eats mainly prawns, small crabs and insects. It may even snack on smaller mudskippers! One study found that it eats mostly fiddler crabs, Medaka fish (Oryzias sp.) and juvenile fishes.

In turn, the fish is preyed upon by the Dog-faced water snake, and birds such as herons, kingfishers. The fish is often seen with mosquitoes biting parts of its body above water.
