Detailed explanation-1: -Pufferfish will “puff up” as a defense mechanism if they are threatened. A shape that is more than double its original size, round and sometimes covered in spines is much more difficult to bite and isn’t very appetizing to a predator.

Detailed explanation-2: -Puffer fish inflation is a defensive measure, and as such, there is no limit to the number of times an individual can inflate (and deflate).

Detailed explanation-3: -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.

Detailed explanation-4: -When they are threatened, they can ingest huge amount of water, and air sometimes, which increases their body size and turn them into large ball-like creatures. This quick transformation scares predators and makes them look harder to eat.
