[citation needed] 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.

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.

[citation needed] It is commonly found on lagoon and seaward reefs in Hawaii, where it thrives among coral structures and feeds on small invertebrates and algae.

[4] Its distribution is largely confined to the Hawaiian archipelago, making it an important part of the local marine biodiversity.
