Lythrypnus dalli, commonly known as the blue-banded goby or Catalina goby, is a species of goby. It is native to the eastern Pacific where it is found from Monterey Bay, California to northern Peru, including the Gulf of California.[1] It can be found in coastal waters at depths of from 0 to 76 metres (0 to 249 ft) 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.[2] This species can reach a length of 6.4 centimetres (2.5 in) TL. It can also be found in the aquarium trade.[3] 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.[4]
