May 21, 2023 · The puffer fish’s ribless skeleton allows it to expand into a tight sphere. When threatened, the fish gulps water quickly and swells into a hard-shelled ball of three times its normal size. It also puffs out spiky spines to make itself even less palatable for predators.

Mar 31, 2024 · Unlike many other fish, pufferfish have specialized bodies that allow for rapid expansion. To understand how inflation occurs, it’s essential to examine their skeleton, skin, and unique muscle and organ structures. 1. Flexible Skin and Skeleton. Pufferfish possess highly elastic skin, which enables them to expand significantly without tearing.

Jun 2, 2023 · In addition to a variety of spines, a puffer fish’s skeleton is remarkably slender and curved, which makes it harder for predators to bite or swallow them whole. Puffer fish also lack ribs and pelvic fins, and have fused bones in their cranium and jaw.
