Porcupine fish are fish belonging to the family Diodontidae (order Tetraodontiformes), also commonly known as blowfish and, sometimes, balloon fish and globefish. They are sometimes collectively referred to as pufferfish, not to be confused with the morphologically similar and closely related Tetraodontidae, which are more commonly given that title.
In shallow temperate and tropical seas worldwide. A couple of species are located much farther from shore, whereas big schools of tens of thousands of people can occur. They are usually slow.
Swallowing air or water, thus becoming rounder. This growth in size (almost twice vertically) reduces the selection of potential predators to people with much bigger mouths. A second defense mechanism is provided by the sharp spines, which radiate outwards when the fish is inflated.
Some species are poisonous, using a tetrodotoxin inside their Internal organs, like the liver and ovaries. This neurotoxin is 1200 times more powerful than cyanide. The poison is produced by various kinds of bacteria obtained from the fish diet. As a result of those three defenses, porcupinefish have few predators, even though adults are occasionally preyed upon by sharks and killer whales.
History of Porcupine Fish
The porcupine fish (as Diodon antennatus) is mentioned in Charles Darwin’s famous account of his trip around the globe The Voyage of the Beagle. He noted how the fish can swim very well when inflated, although the altered buoyancy takes it to do this upside down.
Darwin also said hearing a fellow naturalist, Dr. Allen of Forres, had “frequently found a Diodon, floating alive and distended, in the stomach of the shark and that on several occasions he’s known it eat its way, not only through the coats of the stomach, but through the sides of the creature”.
What do Porcupine Fish Eat?
These fish are present in warm water oceans, especially Along the Atlantic shore. Their diet usually includes sea jellies and mollusks. They hunt at night when they proceed stealthily to locate their prey. They also have a natural tendency to spurt jets of water on their prey. If stored in an aquarium, they can spurt water on different objects when they’re hungry. These fish also eat crabs, oysters, clams, and snails as they have teeth and jaw altered to crush the hard shells of their prey.

Porcupine fish or even the blowfish may also be kept as a pet. After reading these details, we can unanimously agree that the porcupine fish is among the most intriguing and unique aquatic creatures found in the world!
Facts and Data Porcupine Fish
Among the exceptional characteristics of the fish is its Ability of inflating its body to almost double the size. The body of the fish is covered with long sharp spines that stay covered while the body is deflated. When the fish inflates the body, these spines stand out, and it seems like hundreds of needles are protruding from the body. Consequently this fish is known as the porcupinefish.
This is one of its own natural mechanisms to keep predators at bay. When the fish inflates its body, it is simply impossible for the predator to attack. Peculiarly, when a predator gobbles up the fish before it has time to purify its own body, it still inflates itself in the mouth of the predator, which results in the death of the two. Another unique characteristic is that the teeth of this fish are fused together as a single row.
Their reproduction way is likewise very distinct. The male And the female bass partner in the open ocean, or sometimes, a group of males mate with one female. The eggs at this moment, drift into the surface of the sea as a result of currents. If the eggs hatch, the larvae floats on the surface of the water. After the larvae transforms into a small fish, it goes to the bottom of the ocean, in the reef.
Porcupine Fish Family
Porcupine Pufferfish are a small family comprising just 19 individual species, around 6 which are observed in South-east Asian waters. In some species these spines are mended pointing directly. Alternate names include Burrfish and Balloonfish.

Porcupine Pufferfish are found throughout sub-tropical and tropical waters. Some species can be quite common in a particular location.

Porcupine Fish Defences
Pocupine Pufferfish possess an array of highly effective defence mechanisms. They are they can suck water and inflate their bodies to double its original size. In addition, their inflated bodies are coated in short sharp spines making it rather difficult for a predator to have a bite.
Their strong hard jaws – capable of crunching through the toughest of shells – also work well to discourage predators. In case predators are still interested, the flesh of Porcupine Pufferfish is also highly poisonous, including tetradoxin, a very powerful poison. Overall, despite their endearing appearance, Porcupine Pufferfish are more than a match for most predators.
Porcupine pufferfish are often sold dried and dead as Faculties from the tourist trade. They’re also readily stressed and eventually become vulnerable when they have cause to inflate their own bodies too many times. If they inflate near the surface they could inflate with air instead of water, resulting in internal damage.
Porcupine Pufferfish can recognize feeders in captivity and Often behave like puppies, swimming to the very top of the tanks to wait food. They Are ranked as one of those “Smart” fish, using a higher than typical intelligence.
