'''''Canthigaster jactator''''', the '''Hawaiian whitespotted toby''', is a member of the pufferfish family that is endemic to the Hawaiian Islands.<ref>{{FishBase|genus=Canthigaster|species=jactator}}</ref> It occasionally makes its way into the aquarium trade. It grows to a length of {{cvt|9|cm|sp=us}}.
== Description == This fish has a compact, elongated body characterized by a pattern of white spots on a darker background.<ref name=":0">{{cite book |first1=John E. |last1=Randall |year=2007 |title=Reef and Shore Fishes of the Hawaiian Islands |publisher=Sea Grant College Program, University of Hawai'i |location=Honolulu |isbn=978-1-929054-03-9 |pages=560}}</ref> The white spots serve as a form of camouflage, helping it blend in with coral and rocky environments.<ref>{{Cite web |title=An Hawaiian Whitespotted Toby |url=https://www.photoresourcehawaii.com/image/I0000bXxgnwSPC7k |access-date=2024-11-25 |website=www.photoresourcehawaii.com}}</ref> Its head is relatively large compared to its body, and it has a small mouth with teeth that are fused into a beak-like structure.{{cn|date=November 2024}} This unique anatomy is typical of pufferfish, allowing it to consume hard-shelled prey.{{cn|date=November 2024}} Like other members of the pufferfish family, this species is capable of producing tetrodotoxin, a potent neurotoxin that serves as a defense mechanism against predators. The toxin is concentrated in certain tissues and renders the fish highly toxic if ingested.<ref name=":0" />
== Distribution and habitat == The Hawaiian whitespotted toby is endemic to the Hawaiian Islands. Its primary habitat includes the warm, shallow waters surrounding the Hawaiian archipelago, and inhabits coral reefs and rocky areas, where it can find ample shelter.{{cn|date=November 2024}} It is commonly found on lagoon and seaward reefs in Hawaii, where it thrives among coral structures and feeds on small invertebrates and algae. This fish prefer environments with plenty of crevices and ledges, which provide protection from predators. The species is well-adapted to the reef ecosystem, playing a role in maintaining the health of coral habitats.<ref>{{Cite book |date=December 2002 |title=Coral Reef Fishes: Indo-Pacific and Caribbean |edition=Revised |series=Princeton Pocket Guides |first1=Ewald |last1=Lieske |first2=Robert |last2=Myers |location=Princeton |publisher=Princeton University Press |pages=400 |isbn=0691089957}}</ref> Its distribution is largely confined to the Hawaiian archipelago, making it an important part of the local marine biodiversity.<ref>{{Cite book |title=Reproduction in Fishes: Modes of Reproduction in Fishes |first1=Charles M.

== Human use == The Hawaiian whitespotted toby is also known in the aquarium trade, where its striking coloration and compact size make it a popular choice for hobbyists. However, care should be taken when handling or keeping these fish, as they are known to release toxins when stressed, similar to other pufferfish species.<ref>{{Cite journal |last=Stimson |first=John |date=January 2005 |title=Archipelago-wide episodic recruitment of the file fish ''Pervagor spilosoma'' in the Hawaiian Islands as revealed in long-term records |journal=Environmental Biology of Fishes |volume=72 |issue=1 |pages=19–31 |doi=10.1007/s10641-004-4191-8 |bibcode=2005EnvBF..72...19S |issn=0378-1909}}</ref>
