10 of the Most Flexible Animals on the Planet

In this article, “10 of the Most Flexible Animals on the Planet,” Wildlife Informer introduces us to a variety of animals that possess remarkable flexibility. Whether it’s an octopus contorting its entire arm, a hero shrew scrunching up like an inchworm, or a rat squeezing through tiny holes and cracks, these animals use their flexibility to their advantage. From sea lions to owls to elephants, each creature on this list demonstrates the incredible ways in which flexibility plays a vital role in their survival and hunting strategies. Join Wildlife Informer as they explore the fascinating world of these remarkably flexible animals.

The Most Flexible Animals on the Planet

Flexibility plays a crucial role in the animal kingdom, allowing creatures to adapt to their environment and navigate through various challenges. From the depths of the ocean to the vast expanses of land, these are some of the most flexible animals on the planet.


The octopus is undoubtedly one of the most flexible animals on Earth. Unlike many other creatures, the octopus lacks a rigid skeleton in its arms, giving it unparalleled flexibility. Its arms can twist, bend, and even change their thickness and length. This remarkable flexibility enables octopuses to squeeze into incredibly tight spaces, making them masters of escape and evasion. While they do have beaks, the hardest part of their bodies, if their beaks can fit into an area, then the rest of their body can follow suit.

Hero Shrew

Despite its unassuming size, the hero shrew possesses a spine that is interlocking and incredibly flexible. Scientists are still puzzled as to why these shrews have such a unique spine, but what they do know is that this interlocking structure allows the shrew to scrunch its body up like an inchworm. In addition, the hero shrew’s vertebrae can withstand greater force than that of an average animal, enhancing its flexibility even further.

Sea Lions

Sea lions may be large and powerful, but they also possess impressive flexibility. This flexibility comes in handy when hunting for fish, as sea lions can bend their necks back so far that their heads almost touch their backs. Furthermore, they can rotate their hind flippers underneath their bodies, allowing them to walk on all fours. These remarkable feats of flexibility give sea lions a significant advantage in their aquatic habitats.


Snakes are renowned for their incredible flexibility and ability to contort their bodies in various directions. Their flexibility stems from the structure of their spines, which consist of numerous vertebrae running from their heads to their tails. Unlike in other animals, the vertebrae in snake spines do not lock into place, enabling snakes to move with unparalleled agility. Furthermore, snakes can stretch their jaws wide open and in different directions, allowing them to consume prey larger than their heads.


While earthworms may not be the most glamorous creatures, they exhibit remarkable flexibility due to their hydrostatic skeleton. This flexible skeletal structure is filled with fluid, enabling earthworms to move effortlessly through soil and other substrates. Earthworms can range in size from a few inches long to as long as 14 inches. Their bodies are made up of segments called annuli, which aid in their movement and burrowing through the soil.


Weasels may appear cute and harmless, but their flexible bodies make them formidable predators. With their ability to squeeze themselves into small spaces, weasels can navigate tight crevices and burrows in pursuit of their prey. Coupled with their sharp teeth and agility, their flexibility gives them an advantage in catching small rodents and birds. While they may not be the largest creatures on this list, weasels certainly make up for it with their flexibility and cunning nature.


Centipedes are known for their flexibility, thanks to their exoskeleton and long legs. Their exoskeleton provides them with support while allowing for a wide range of movement. Unlike millipedes, centipedes do not curl up when touched, maintaining their flexibility and agility even when faced with potential threats. These fascinating creatures can quickly traverse across various surfaces, making them highly adaptable predators in their environments.


Despite their seemingly unassuming appearance, owls possess a surprising amount of flexibility. Their most well-known feat is their ability to rotate their heads an astonishing 270 degrees to the right and left. This exceptional range of motion allows owls to detect prey and avoid predators, even when their bodies remain stationary. With fixed eye sockets facing forward, their flexible necks are essential for survival in the wild.


Rats are notorious for their ability to squeeze through seemingly impenetrable barriers. Their cylindrical and flexible bodies enable them to fit through small holes and cracks, making it challenging to keep them out of unwanted areas. Rats rely on their whiskers, located on the sides of their faces, to determine if they can fit through a particular opening. If their whiskers can fit, then they can effortlessly maneuver their bodies through, no matter how tight the space.


It may come as a surprise, but elephants are among the most flexible creatures on the planet. While they are commonly known for their size and strength, their trunks are marvels of flexibility. An elephant’s trunk contains approximately 100,000 tendons and muscles, giving it unparalleled dexterity and strength. This incredible flexibility allows elephants to manipulate and move their trunks in various directions, enabling them to gather food, suck up water, and interact with their surroundings.

In conclusion, flexibility is a vital attribute in the animal kingdom, enabling animals to adapt, escape danger, and thrive in their environments. From the dynamic movements of octopuses to the contortions of snakes, these remarkable creatures showcase the astonishing range of flexibility found in the animal kingdom. Understanding the unique adaptations and capabilities of these animals provides us with a deeper appreciation for the diversity and resilience of life on Earth.
