The sleepy goby (Psammogobius biocellatus) is a species of fish in the family Gobiidae.
Psammogobius biocellatus is a goby which varies in colour from dark brown to blackish, marked with rows of small black spots along its flanks and 2-3 dark blotches along the back and upper flanks. There is a dark band on the first dorsal fin with more dark bands on the lower part of the caudal fin and narrow bands on the pelvic fins. [2] It attains a maximum total length of 12 centimetres (4.7 in). [3]
Psammogobius biocellatus is a widespread species and is distributed East Africa and through the Western Indian Ocean and the Pacific as far east as Fiji and Samoa, north to Japan and south to Australia. [1]
The sleepy goby occurs in the intertidal zone in estuaries, lagoons and coastal rivers, often amongst mangroves where it burrowing into the silty-sand substrate, it may also be found in the lower reaches of freshwater streams. [1] It buries itself in the sand. [2]
Eucyclogobius newberryi, the Northern tidewater goby, is a species of goby native to lagoons of streams, marshes, and creeks along the coast of California, United States. The Northern tidewater goby is one of six native goby species to California.
The sand goby, also known as a polewig or pollybait, is a species of ray-finned fish native to marine and brackish waters European waters from the Baltic Sea through the Mediterranean Sea and into the Black Sea where it occurs in sandy or muddy areas of inshore waters at depths of from 4 to 200 metres. This species can reach a length of 11 centimetres (4.3 in) TL. This species is sometimes kept in public aquariums. The sand goby is of a sandy colour, with darker markings on the sides and a creamy-white underside.

The channel darter is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is native to North America where it typically occurs in the sandy or gravelly shallows of lakes and in small and medium-sized rivers in riffles over sand, gravel or rock bottoms. It is a small fish ranging from 34 to 72 mm in length, olive brown with darker speckles and sometimes with a dark spot below the eye and dark blotches along the flank. It feeds mostly on insect larvae and other small invertebrates and breeds in small streams. This species is listed as threatened by the Canadian Species at Risk Act (SARA) but overall it has a wide range and numerous sub-populations and the International Union for Conservation of Nature has rated it as a "least concern species".

The largetooth goby, also known as Wilbur's goby, is a species of ray-finned fish from the family Gobiidae which is native to the Indo-Pacific from the Seychelles to Micronesia. Its known range has been extended to the Red Sea as specimens were photographed at one site and collected at another site off Egypt. This species lives in sheltered marine waters at depths of from 0 to 20 metres preferring areas with sandy substrates. This species grows to a length of 6.5 centimetres (2.6 in) SL. This species is the only known member of its genus. This species is not obviously sexually dimorphic and it has a background colour of pale brown to greenish-brown and a pale ventral side. The body is marked with brown and white spots, pairs of larger brown spots create a mid-lateral row along its flanks and there is a dark spot on the caudal fin peduncle. It has a brown blotch on the cheek and a series of short brown bars along its back. The largetooth goby is a solitary fish which is found in coastal bays, lagoons and estuaries over fine sandy substrates close to the margins of reefs or silt beds in the vicinity of sheltered and often turbid coastal reefs. It is most frequently collected from shallow waters to 7 metres (23 ft), around coral reefs but off southern Japan, the largetooth goby occurs at the bottom of sandy bays. The specific name honours the American physician, Ray Lyman Wilbur (1875–1949) who was president of Stanford University from 1916–1943, as well as being the United States Secretary of the Interior from 1929–1933. Wilbur helped the author, Herre, get to Palau, the type locality of this species.
