Do puffer fish die after they inflate?
Do Pufferfish Die When They Puff Up Actually, it is not the puffing that makes them dead. It is actually their extreme levels of stress and tetrodotoxin poison in the body which disturb the fish. They inflate themselves so much that the stress levels exceed their normal limit and they die inflated.
What happens if you touch a puffer fish?
Poison spikes: One of the adaptations that helps the pufferfish survive is the ability to produce a poison known as tetraodotoxin. This toxin is secreted across their body, making puffers dangerous to touch and even more dangerous to consume.
What is the deadliest fish in the sea?
Of the estimated 1,200 venomous fish species on Earth, the stonefish is the most lethal – with enough toxin to kill an adult human in under an hour. Thankfully, effective anti-venoms are available, though these need to administer quickly to prevent severe symptoms like tissue necrosis, paralysis and heart failure.
What happens if a puffer fish puffs out of water?
When a puffer fish puffs up, it takes in water to increase the size. This violently forces the puffer’s organs to be pressed to the side, inside the body causing the organs to flatten. This creates an extreme amount of stress for the puffer fish. In some cases the puffer fish dies from this stress.
How many times can puffer fish inflate?
Pufferfish can instinctually inflate their bodies whenever they feel threatened as soon as they hatch. This helps them appear more intimidating to potential predators. When the pufferfish matures it can use this defense mechanism to full effect, allowing the fish to puff up to three times its original size.

How are porcupinefish able to inflate their bodies?
They are generally slow-moving. Porcupinefish have the ability to inflate their bodies by swallowing water or air, thereby becoming rounder. This increase in size (almost double vertically) reduces the range of potential predators to those with much bigger mouths.
What makes a porcupine fish poisonous to humans?
A second defense mechanism is provided by the sharp spines, which radiate outwards when the fish is inflated. Some species are poisonous, having tetrodotoxin in their internal organs, such as the ovaries and liver. This neurotoxin is at least 1200 times more potent than cyanide.
