Editing Triggerfish (section)

===Male territoriality===

Triggerfish males migrate to their traditional spawning sites prior to mating and establish territories. Some male species (i.e.'' [[Balistes carolinensis]]'' and ''[[Pseudobalistes flavimarginatus]]'') build hollow nests within their territories.<ref>{{cite journal|last1=Lobel|first1=Philip S.|last2=Johannes|first2=Robert E.|date=September 1980|title=Nesting, egg and larvae of triggerfish (Balistidae).|journal=[[Environmental Biology of Fishes]]|volume=5|issue=3|pages=251–252|doi=10.1007/bf00005359|bibcode=1980EnvBF...5..251L |s2cid=3213367}}</ref> Triggerfish males are fierce in guarding their territories as having a territory is essential for reproduction. A male's territory is used for spawning and parental care. Most male territories are located over a sandy sea bottom or on a rocky reef. A single territory usually includes more than one female, and the male mates with all of the females residing in or visiting his territory ([[Polygyny in animals|polygyny]]). In Hachijojima, [[Izu Islands]], Japan, one male crosshatch triggerfish (''[[Xanthichthys mento]]'') has up to three females in his territory at the same time, and mates with them in pairs. Each male red-toothed triggerfish (''[[Odonus niger]]'') mates with more than 10 females in his territory on the same day.<ref name=":6">{{cite journal|last=Kawase|first=Hiroshi|date=March 2003|title=Spawning behavior and biparental egg care of the crosshatch triggerfish, ''Xanthichthys mento'' (Balistidae).|journal=[[Environmental Biology of Fishes]]|volume=66|issue=3|pages=211–219|doi=10.1023/a:1023978722744|bibcode=2003EnvBF..66..211K |s2cid=35997227}}</ref> Yellow margin triggerfish (''[[Pseudobalistes flavimarginatus]]'') also exhibit polygyny.
