Description
The longspine porcupinefish is pale bodie with big, dark blotches and small dark spots. These spots usually fade with age. There are two depressible spines on its head. Teeth from both its jaws are fused into a "beak".
Behavior
It is a nocturnal fish, meaning it is more active at night to hunt food. When it feels threatened, it can inflate its body up to twice its size by swallowing water to its sac near the belly. It also erects its spines, making it look scarier, bigger, and more unappetizing to predators.
Reproduction
Spawning occurs on the surface at dusk or dawn, in pairs or in groups of males with one female.
Communication & Perception
They are known to create sounds by grinding their teeth or vibrating their swim bladders to communicate.
Predator
Hiu macan (Galeocerdo cuvier)
Conservation Status : Least Concern (IUCN Red List; 2011)
Fun Fact
Just like all the member of Tetraodontidae, the long-spine porcupinefish's spines aren't venomous, but they are poisonous! The liver and gonad contain tetrodotoxin, a neurotoxin that affects the nerve tissues
