Way of livingdiurnal
Tetrodotoxin or TTX is a neurotoxin produced by bacteria. In this species, it is present in large quantities in the liver, viscera and gonads but is also found in the skin.
Females are more toxic than males, this is due to the high concentration of TTX in the ovaries.
When poisoned, TTX is fatal in more than 50% of cases. This neurotoxin acts on the pores of the sodium channels, which stops the passage of nerve impulses, resulting in partial or total paralysis. Death is most often due to respiratory paralysis triggering cardiac arrest by collapse.
Lactoria fornasini is a fish solitary naturally found at mid-depth and near the bottom. This species is omnivorous with herbivorous tendency .
n general, this species does not care much about other animals crossing its path. However, she may show some signs of aggression with conspecifics.
