This looks like something a kid could make for the backyard swimming pool or bathtub. The deflation step is the easy part. How do you make an autonomous robot repeatedly inflate and aim itself? And how do you put eight flexible arms on it that a central brain can direct, allowing it to move in any direction over any surface?
A more sophisticated octopus robot announced by Waseda University has four arms and four tank-like tread wheels. Octopuses are also fascinating for their adaptability to a wide range of habitats.
Some live in shallow water tide pools; others survive in abyssal depths and near hydrothermal vents. The rapid color-change trickery of the octopus and other cephalopods is another marvel that engineers are trying to master. This octopus was discovered in off the coast of an Indonesian island, and is perhaps the greatest shape-shifter of all.
Similar to the cuttlefish, it is capable of mimicking its background environment by changing the colour and texture of its skin. However, impressively, it is the only animal able to mimic a diverse range of species — at least 13 have been recorded so far — including lion fish, sea snakes, jellyfish and sea anemones.
As we observed last year , the octopus even has control programs and mechanisms to prevent its semi-autonomous arms from tying themselves in knots. All the parts must match and act in concert for these complex functions. Our findings suggest that the soft molluscan body has affected in an embodied way the emergence of the adaptive motor behavior of the octopus.
Clearly the octopus is an extremely well-designed animal for its marine environment. Does Darwinism offer any understanding of how a snail or clam transmogrified into an octopus? End of story. Ammonite fossils occur in places in the Cretaceous of Delaware.
An ammonite can be thought of as an octopus stuffed inside a straight, coiled, or spiral shell. Most of the larger coiled ones are found in the Merchantville Formation. Sections of the straight-shelled Baculites are more common in the Mount Laurel Formation. The belemnite species Belemnitella americana is the Delaware State Fossil. They are amber colored, bullet-shaped fossils that served as the internal skeleton in an extinct squid-like animal called a belemnoid.
Belemnites are a common find on the Mount Laurel spoils pile because they probably traveled in large schools. Mollusks M aybe you think that snails, clams, mussels, squid, and octopods are very different. Yet, they are all in the same category of animals known as mollusks and are structurally similar.
Mollusks are some of the most well known of invertebrate sea creatures there are over 50, species. Some are very rare and are only found in very deep-water.
Mollusks have three body regions. The head contains the "brain" and the sense organs. The "visceral mass" contains the internal organs. The "foot" is the muscular part of the body. Mollusks usually, but not always, have a shell, which is secreted by a body wall called the mantle. Many mollusks have a tongue of sorts, called a radula. The radula is rough like sandpaper. Mollusks have well developed body organs that are used in the respiratory, circulatory and nervous systems.
The stomach-foots include snails, limpets and abalones, which have shells. Slugs and nudibranchs are also stomach-foots, but do not have shells.
