It is found in the eastern pacific Ocean. DescriptionMicrospathodon bairdii is a large damselfish, reaching {{convert|25|cm|in}} in standard length.[3] The adults are dark brown or black, have purple eyes and sport a large bump on their foreheads while the juveniles are bright blue on their backs, with orange or yellow on the underside.[4]DistributionMicrospathodon bairdii is endemic to the Eastern Pacific where its occurs from the mouth of the Gulf of California in Mexico south to Ecuador. Its range includes the Revillagigedo, Cocos, Malpelo and Galapagos Islands.[1]Habitat and biologyMicrospathodon bairdii occurs on rocky inshore reefs which are exposed to wave action and to currents, being found down to {{convert|15|m|ft}}. It is most frequently recorded in the vicinity large boulders in the shallow subtidal zone. In the Gulf of Chiriquí, Panamá, the bumphead damselfish is found among huge corals and exposed shallow rocky reefs.[1] It is mainly herbivorous, feeding on algae, but will take a hook baited with animal matter[3] and will readily eat meat in the aquarium.[4] They form pairs to breed and the eggs are laid in crevices in rocks where there is a strong current, on the leeward side of the current. The eggs are hoarded and aerated by the male.[3]EtymologyThe person that Gill was honouring with the specific name has not been identified but it is very probably Spencer Fullerton Baird who was director of the United States National Museum where the type specimen is located.[5] References1. ^1 2 {{cite journal | author1 = Allen, G. | author2 = Robertson, R. | author3 = Rivera, R. | author4 = Edgar, G. | author5 = Merlen, G. | author6 = Zapata, F. | author7 = Barraza, E. | display-authors = 3 | year = 2010 | title = Microspathodon bairdii | journal = The IUCN Red List of Threatened Species | volume = 2010 | page = e.T183472A8119307 | doi = 10.2305/IUCN.UK.2010-3.RLTS.T183472A8119307.en }} {{Taxonbar|From = Q2162629}}2. ^{{Cof record|spid=22328|title=Microspathodon bairdii|access-date=7 October 2018}} 3. ^1 2 {{FishBase|Microspathodon|bairdii|month=June|year=2018}} 4. ^1 {{cite web | url = http://www.saltcorner.com/AquariumLibrary/browsespecies.php?CritterID=776 | title = Microspathodon bairdii | accessdate = 7 October 2018| publisher = Bob Goemans}} 5. ^{{cite web | url = https://www.etyfish.org/pomacentridae/ | title = Subseries OVALENTARIA (Incertae sedis): Family POMACENTRIDAE | accessdate= 7 October 2018 | author1 = Christopher Scharpf | author2 = Kenneth J.
