The term may also refer to only those creatures in the genus Octopus. The wonderpus doesn't have this line and the mimic will always have it, allowing for clear identification.The octopus is a cephalopod of the order Octopoda that inhabits many diverse regions of the ocean, especially coral reefs. The best way to differentiate the mimic form the wonderpus is the white line that runs along the bottom of each tentacle of the mimic. While the Wonderpus has fixed bands on its legs, the Mimic may or may not have the bands, so that's a tough way to distinguish between the species when underwater. The Wonderpus Octopus ( Wunderpus photogenicus). It pays to be patient and wait for the right moment to push the shutter. You might get some likes on your post with a photo of a defensive subject, but that photo would never win a contest with experts who know the octopus behaviors. Why is this a photo tip? Because once harassed, the Octopus behaves differently than if you stalk it naturally hunting, swimming or remaining frozen. I often find myself frog kicking sideways or backwards when shooting mimics so it's critical to make sure you know what's "in front of you". No photo is worth injuring yourself, the reef or any critters there, so make sure to look where you're going.

On full frame, I shoot at either 100mm or 40mm. DSLR: On crop sensors, a 60mm lens is a great choice.Mirrorless: The 60mm lens is a great choice.Compact Shooters: Remove your wet diopter and wet wide-angle lens.Your macro lens will provide too much magnification while a wide-angle lens will render the mimic octopus very small in the frame. Photo Tips 1) Use a Mid-Range Focal Length Once located, the mimic will trap the prey in the suckers on any of their 8 tentacles, then moving the prey to their mouth. Mimics are most active early morning and in the evening, finding their way across the substrate while feeling inside holes and under rocks for small crustaceans and fish. Often dive guides will look for mimic octopuses right at the start of the dive or at the end during a surface interval.
Naturally brown in color, they prefer open sand / silt bottom in relatively shallow water. Below are UWPG's favorite locations for Mimics, where you can find them along with many other critters: Mimic Octopuses are found all over the Indo-Pacific (Indonesia, Philippines, Malaysia, Papua New Guinea, etc). The Mimic Octopus also has a few other impersonations that are less frequently seen, including forms that look like jellyfish and lionfish. And most predators have no desire to approach a poisonous sea snake. A flatfish is not very interesting moving quickly across the sand. It's remarkable to think that the Mimic Octopus has evolved to mimic certain creatures in its environment when it will be advantageous. Or does that look like a banded sea snake? Or does that look like a flatfish? They generally live and seek protection in holes in the sand, often leaving two banded tentacles of of the hole - one in a defensive posture and one extended and waving slightly. Mimics are most often seen by divers on sandy substrate and when they want to cover ground quickly will form a shape that looks like an oval spaceship floating over the sand. It happens very quickly, with creativity that would make a superhero jealous. So what's different about the mimic octopus? Like the name implies, the mimic octopus can mimic serveral different fish and critters with startling accuracy. The combination of these features allows octopuses to camouflage themselves on the reef, sand, rubble or open water and hide from would-be predators.
#Octopus predators skin#
Like all octopuses, the mimic has chromatophores that produce color pigments in a range of patterns and colors, as well as the ability to change skin texture. The Mimic Octopus (Thaumoctopus mimicus) is one of the most remarkable cephalopods in the ocean, delighting scuba divers and underwater photographers with every encounter.
