Family: Oxudercidae (Subfamily Oxudercinae - Mudskippers)
Species Name: Periophthalmus walailakae
Common Name(s): Yellow-spotted Mudskipper, Walailak's Mudskipper
Common Name(s): Yellow-spotted Mudskipper, Walailak's Mudskipper
Presence in Singapore: Native
Habitat: Coastal: Mangrove forests
Conservation status: Vulnerable (Red Data Book 3)
This is a large mudskipper species for its genus, reaching nearly 13cm in length at max. It is relatively common in our muddy mangrove forests but can also be seen further out along the shore, sometimes in sandier habitats. The top half of its body has several saddle-like stripes while its flanks are covered with yellow spots, giving it the common name it's known by locally. Its first dorsal fin is un-patterned, being red with black and white margins along the top down to the back.

The Yellow-spotted Mudskipper is an opportunistic carnivore, preying on small crustaceans and other invertebrates. Its burrows are usually further back in the mangroves in mud and it doesn't seem to stray far from the shelter of the mangrove forests.
