The animal kingdom is full of incredible examples of camouflage, with animals resembling objects found in their environment such as sticks or leaves , or displaying colour patterns that permit them to blend into their surroundings to hide from predators or prey. Many animals interact with the world using other senses, such as smell. Yet most of our understanding of animal camouflage is based on visual mechanisms, probably due to our own reliance on sight.
Can animals camouflage their own smell to avoid detection? As predators often use smells to locate prey, even the visually camouflaged can stick out if they still smell strongly like lunch. In a paper published by the Royal Society, our study reveals that a small colourful fish, the harlequin filefish , can change its odour to hide from hungry predators.
Evolution has a tendency to produce countermeasures in this way; an animal could employ some mechanism to mask or diminish its odour, either by limiting the smell it produces, or altering it to match smells present within its habitat. Mimicry, Color change The mimic octopus is an expert of shapeshifting.
It is able to mimic the look and movement of more than fifteen species including sea snake, lionfish, flatfish, fish, frogfish, brittle stars, giant crabs, shellfish, rays, sea anemones, jellyfish or mantis-shrimp.
Pretty hard to imagine, right? Your biggest chance to see a mimetic octopus if you wish so is to dive here : Serava Secret , Bali. You know another amazing expert of camouflage?

From Europe to Asia, […]. Madagascar is a fantastic island that contains many mysteries whether on land or under water. Sometimes covering itself in algae, their disguises are so accurate that its prey sometimes approach thinking that painted frogfish are food, before becoming a meal themselves. And with the ability to strike in less than 6 milliseconds and a large mouth so it can eat prey the same size as itself, it certainly spells trouble for any small fish and crustaceans that pass by.
The extensible body of a frogfish is usually covered in spots, stripes, blotches, and filaments. This allows the species to imitate its surroundings and become hidden from predators too. Top fact: the frogfish is named due to the fact its skin and legs resemble a frog, despite still being a species of fish. The lionfish, just like the reef stonefish, is another incredibly venomous species of fish, whereby its sting can cause severe pain and possibly even death on rare occasions.
The common species of lionfish has a transparent dorsal fin that is also covered with dark spots — allowing it to blend into its surroundings, such as coral and gorgonian sea fans. There are currently 12 known species of lionfish, all ranging in different colours and patterns.
Even when swimming they look like drifting leaves waiting for their prey. And as small as they are, they are very capable of surviving due to their large heads, well camouflaging colour and big mouths with which they can eat prey almost as big as they are. The decorator crab is not only one species of crab, but they are several different species of crab using the same way of camouflage.
They do this by sticking materials from their environment such as other animals and plants on their body. All this to blend into the surrounding and hide from their predators.
Flatfish are species that live on their side on the bottom of the ocean. For this reason both eyes grow on one side of the head, either the left or the right side. These creatures which are almost always hidden underneath the sand, change colour depending to their environment. They do this to hide from their predators and in the meantime they eat the prey passing by.
Depending on their background, robust ghost pipefish may be grey, brown, pink, yellow or green with small white and black dots. To blend in the best they can, they will mostly be near algae or seagrass beds. Besides this, robust ghost pipefishes are extremely seasonal, which means they will be only findable for a few months a year. These months are those where the water is the warmest.
