Javichthys kailolae is known from the Bali Strait, Indonesia and off Batangas, Philippines, although further deep-water sampling may expand its range. It is a benthopelagic species which has been collected at depths ranging from 62 to 68 metres. There is limited information available on its population status, life history characteristics and general biology. There are no known species-specific threats to J. kailolae. It is a relatively deep-water species which has been collected from two widely separated localities, and is likely to be undersampled. Therefore it is listed as Least Concern.

Population [top]

Population:Javichthys kailolae is infrequently collected, and may be rare. It is primarily known from the original species description of 12 specimens (Hardy 1985). Nine additional specimens have been collected off the coast of Batangas, Philippines. Specimens of J. kailolae are uncommon in museum collections Accessed through the Fishnet2 Portal,, 2010-04-30). There are no additional specimens known to have been collected since 1966.

Habitat and Ecology [top]

Habitat and Ecology:Javichthys kailolae is benthopelagic species. It was collected at depths ranging from 62 to 85 m depth off the southern coast of Java (Hardy 1985). 

Tetraodontids are characterized by a tough skin that is often covered with small spinulous scales, a beak-like dental plate divided by a median suture, a slit-like gill opening anterior to the base of the pectoral fin, no pelvic fins, no fin spines, a single usually short-based dorsal fin, a single usually short-based anal fin, and no ribs. They are capable of inflating their abdomens with water when frightened or disturbed and are capable of producing and accumulating toxins such as tetrodotoxin and saxitoxin in the skin, gonads, and liver. The degree of toxicity varies by species, and also according to geographic area and season (Allen and Randall 1977, Allen and Erdmann 2012). Fishes in the family Tetraodontidae have the smallest vertebrate genomes known to date (Neafsey and Palumbi 2003).
