octopus : any of a genus (Octopus) of cephalopod mollusks that have eight muscular arms equipped with two rows of suckers; broadly : any octopod excepting the paper nautilus — Webster
Octopus is a soft-bodied, eight-armed mollusc of the order Octopoda. Around 300 species are recognized and the order is grouped within the class Cephalopoda with squids, cuttlefish and nautiloids. Like other cephalopods, the octopus is bilaterally symmetric with two eyes and a beak, with its mouth at the centre point of the arms (which are sometimes mistakenly called “tentacles”). The soft body can rapidly alter its shape, enabling octopuses to squeeze through small gaps. They trail their eight arms behind them as they swim. The siphon is used both for respiration and for locomotion, by expelling a jet of water. Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviorally diverse of all invertebrates. — Wikipedia

Sea turtles find protection from Senegal fishermen
on July 3, 2020 at 8:50 am
In a classic case of "poacher turning gamekeeper", the fishermen of Senegal have joined forces to protect one of the ocean's most endangered species—the sea turtle.
Butterfly-inspired nanotech makes natural-looking...

Taking inspiration from nature's nanotech that creates the stunning color of butterfly wings, a University of Central Florida researcher is creating technology to make extremely low-power, ultra-high-definition displays and screens that are easier on the eyes.

A pair of researchers, one with Newcastle University in the U.K, the other the National Museum of Natural History in Washington D.C., has captured video footage of a cephalopod at the deepest ocean level ever observed. In their paper published in the journal Marine Biology, Alan Jamieson and Michael Vecchione describe how they used "landers" to capture video remotely at the bottom of the Indian Ocean, and what they found.

Octopuses, squids and other sea creatures can perform a disappearing act by using specialized tissues in their bodies to manipulate the transmission and reflection of light, and now researchers at the University of California, Irvine have engineered human cells to have similar transparent abilities.
Evolutionary flaws disprove the theory of...

Evolution has produced countless amazing life forms, but you need look no further than to the human body to find examples showing that evolution has also produced a number of poor constructions."The many flaws of evolution makes it impossible to believe in the theory of intelligent design," says Professor Glenn-Peter Sætre at the University of Oslo.
