Graham's gudgeon, Grahamichthys radiata, is a species of goby of the family Thalasseleotrididae, the only member of the genus Grahamichthys. This species is found in rock pools and in the neritic zone, to 50 metres (160 ft) in depth, where sand or mud is lies around and partially buries rocks, shells, or other objects. It is unusual for a goby, in that it lives in loose schools. The generic name is a compound formed from the surname Graham in honour of David H. Graham who wrote A Treasury of New Zealand Fishes which was published in 1953 and therefore is an allusion to this taxon being endemic to New Zealand and the Greek ichthys meaning "fish".

Astroblepus is a genus of fish in the family Astroblepidae found in South America and Panama. This genus is the only member of its family. These catfishes are primarily found in torrential streams in the Andean area. Astroblepus pholeter and A. riberae are troglobites adapted to living in subterranean water systems. These species are typically small, less than 10 cm (4 in). The largest species reaches 30 cm (1 ft). These fish have suckermouths like those of loricariids. They have two pairs of barbels, maxillary and nasal. The dorsal fin spine lacks a locking mechanism. These fish also have odontodes, tiny teeth on their skin. All species exhibit a conical, pointy type on their fin rays like that found in other loricarioids; other species also exhibit a blunt type that is only found on their skin.
Lythrypnus dalli, the Blue-banded goby or Catalina Goby is a species of goby native to the eastern Pacific from Monterey Bay (California) to northern Peru, including the Gulf of California. It can be found in coastal waters at depths of from 0 to 76 metres with rocky substrates in which there are crevices for concealment. It is also known to hide amongst the spines of sea urchins. It is a bidirectional hermaphrodite and capable of rapidly switching sexes. This species can reach a length of 6.4 centimetres (2.5 in) TL. It can also be found in the aquarium trade. The specific name honours the malacologist William Healey Dall (1845-1927), who when trawling for specimens off Catalina Harbour, California, caught one of the type specimens.
