Pufferfish are also known to use their beaks to puncture the squid’s body and suck out the contents. Some are specialized predators and have evolved unique hunting strategies to catch their preferred food.

Pufferfish use a combination of physical force and toxins for hunting and eating squid. Some pufferfish species are known to produce a potent toxin called tetrodotoxin. It can paralyze and kill their prey. This toxin is also found in the pufferfish’s own flesh and organs. It makes them toxic to predators and humans who consume them.

Moreover, with their strong jaws and beaks, they can easily crush and grind their food before swallowing. To aid in digestion, pufferfish have a unique stomach structure that includes a muscular gizzard-like organ. This organ helps to grind and crush food before it enters the intestines. It is further broken down here and nutrients are absorbed. (Source)
