This suborder contains mainly gobies. Gobies are characterised by their disc-shaped pelvic fins, which form a sucker that allows them to hang on to surfaces. Mudskippers are gobies, which have adapted to living out of water. Gobies are generally small fish, although the Giant Mudskippers can grow up to 30 cm long.
The Marbled Goby or Soon Hock (Oxyeleotris marmorata) is a common dish on the table. It is not a True Goby (Family Gobiidae), but belong to the Family of Sleeper Gobies (Family Eleotridae).
There are a few Istigobius species in Singapore. The Goldman's Goby or Black-spotted Lagoon-goby (Istigobius goldmanni) can be told apart from the others by the double blacks spots on the sides of the body.
Mudskippers are fascinating because they can stay out of water for a period of time. They are part of the Goby family. There are more than 10 species that can be found in Singapore. The more common ones are the Giant, Blue-spotted, Gold-spotted and Yellow-spotted. The Giant Mudskipper is the largest of them all. It has a black stripe along the whole length of the body. The Blue-spotted Mudskipper has several black stripes on its body and blue spots all over, but more on the face.
Gold-spotted Mudskipper has orange spots all over its body. Yellow-spotted Mudskipper has yellow spots all over the body and the second dorsal fin has a black stripe in the middle.
Bearded and Elongate Mudskippers both have a longish body, but the former has a bluish belly and a tall dorsal fin when raised.
