a BIPED land animal! How could it possibly... it is perfectly emulating not only an animal in form, but performing the MECHANIC of walking on land, which is something land dwelling animals took millions of years to evolve, in gravity. Truly, I am amazed. Thanks.edit on 24-9-2012 by ecapsretuo because: (no reason given)
There are some species of fish that can "walk" along the sea floor but not on land; one such animal is the flying gurnard (it does not actually fly, and should not be confused with flying fish). The batfishes of the Ogcocephalidae family (not to be confused with Batfish of Ephippidae) are also capable of walking along the sea floor. The African lungfish (P. annectens) can use its fins to "walk" along the bottom of its tank in a manner similar to the way amphibians and land vertebrates use their limbs on land
However, saving the best for last, this Walking Frog Fish seems to resemble the most what this Mimic Octopus was mimicking.
Mimicry and camouflage
A frogfish disguised as an algae-covered stone
The unusual appearance of the frogfish is designed to conceal it from predators and sometimes to mimic a potential meal to its prey. In ethology, the study of animal behavior, this is known as aggressive mimicry. Their unusual shape, color, and skin textures disguise frogfish. Some resemble stones or coral while others imitate sponges, or sea squirts with dark splotches instead of holes. In 2005, a species was discovered, the striated frogfish, that mimics a sea urchin while the sargassumfish is colored to blend in with the surrounding sargassum. Some frogfish are covered with algae or hydrozoa. Their camouflage can be so perfect, that sea slugs have been known to crawl over the fish without recognizing them.
For the scaleless and unprotected frogfish, the camouflage is an important defense against predators. Some frogfish can also inflate themselves, like pufferfish, by sucking in water in a threat display. In aquariums and in nature, frogfish have been observed, when flushed from their hiding spots and clearly visible, to be attacked by clownfish, damselfish, and wrasse, and in aquariums, to be killed.
Many frogfish can change their color. The light colors are generally yellows or yellow-browns while the darker are green, black, or dark red. They usually appear with the lighter color, but the change can last anywhere from a few days to several weeks. It is unknown what triggers the change.

Wow I can't believe Ive never heard of this beautiful creature before!!
Just what else is down there!!!!
AMAZING. 10/10 Flagged!!
Predatory tunicates (Megalodicopia hians) are tunicates which live anchored along the deep sea canyon walls and seafloor, waiting for tiny animals to drift or swim into their hood-shaped mouths. Looking something like a cross between a jellyfish and a Venus Flytrap, its mouthlike hood is quick to close when a small animal drifts inside. Once the predatory tunicate catches a meal, it keeps its trap shut until it is ready to eat again. They are known to live in the Monterey Canyon at depths of 200-1,000 m (656-3,281 ft).
Salp chain, Pegea sp., 9 miles off San Diego, California (c) Richard Herrmann
A salp (plural salps; also salpa, plural salpae or salpas) is a barrel-shaped, free-floating tunicate. It moves by contracting, thus pumping water through its gelatinous body. The salp strains the pumped water through its internal feeding filters, feeding on phytoplankton that it sieves out of the water.
Salps are common in equatorial, temperate, and cold seas, where they can be seen at the surface, singly or in long, stringy colonies. The most abundant concentrations of salps are in the Southern Ocean (near Antarctica). Here they sometimes form enormous swarms, often in deep water, and are sometimes even more abundant than krill. Over the last century, while krill populations in the Southern Ocean have declined, salp populations appear to be increasing.
Salps are colonial pelagic tunicates that can grow truly enormous. Sure, they look all slimy and featureless, but tunicates are our closest relative in the invertebrate world. Most chordates can only live as solitary individuals (booooring) but tunicates also live as colonies of genetically identical clones (no other chordate can do that!).
Colonial tunicates pretty much have chordate superpowers. They can absorb and regenerate organs or even entire clones without batting an eye. If broken into fragments, they can reattach, grow, and thrive. Creepily, if a colony comes into contact with either its parent or sibling colony, the colonies will fuse and become one uber-colony.
Creepiest of all, the golden star tunicate (Botryllus schlosseri) has parasitic stem cells. When two colonies fuse, the stem cells battle it out for who gets to control the genes that go into reproduction. Whoever wins gets to pass its genome to the next generation. Whoever loses…well, that’s natural selection.
Tunicates laugh in the face of pollution. If you go to the most godforsaken stinkiest backwater harbor, you’ll probably find tunicates growing there. Many species eat copper antifouling paint for breakfast and wash it down with some tasty fecal bacteria. Harbor-dwelling tunicates travel all over the world on the bottoms of boats and then happily establish themselves in a new home. That’s why most temperate harbors all over the world have similar tunicate species – they’ve managed to migrate. Not bad for something that can’t move on its own.
Tunicates can also kick ass in tropical systems. One Caribbean species, Trididemnum solidum, is overgrowing apparently healthy corals. Trididemnum is the mack truck of tunicates, combining incredibly toxic poisons with spiny spicules to ward off predation. And it’s not even dependent on outside food – it has a symbiotic algae that makes yummy sugars right in its cells.
Additionally, tunicates are noble warriors against climate change. The pelagic tunicates are waging a mighty battle against climate change by exporting all the carbon they can.

That is so cool.
Do you think that maybe we are seeing a stage of evolution where the fish go from being fish to land creatures? Not sure i worded that right but you know what i mean?
