Wow! These Octopus Walk On The Beach

Octopus weird act

A few days ago, there was a rare occurrence in the region of Wales, England. More than 20 octopuses emerge from the sea and walk on the shore of New Quay, Ceredigion, Wales, for three consecutive nights.

In fact, the eight-legged animal is rarely seen and live 100 meters below sea level. This phenomenon of course makes the scientists confused.

"This does not fit the breed behavior or the way they feed," says James Wright, curator at National Marine Aquarium, Plymouth, quoted by the Daily Mail Online (31/10/2017).

"There are some videos that show them (octopus) coming out of the shadows of the sea to hunt, but if they go up to the beach, then this is not unusual," Wright added.

In response to this strange behavior, scientists also argue that octopuses out of their habitat due to the influence of bad weather and changes in atmospheric pressure. Moreover, recently there was a storm Ophelia and Brian who destroyed the Irish sea.

Hurricane Ophelia, followed by Hurricane Brian at the beginning of last month, caused huge waves and storms of up to 80 miles per hour on the coast of Wales. "The octopus shows an unusual behavior similar to the two areas affected by low-pressure depression due to Ophelia and Brian storms, and that's what's affecting them," Wright told the Telegraph.

Dr Steve Simpson, marine biologist at Bristol University also revealed that the octopus behavior is very strange. "It's hard to imagine they've found new food sources They may do it to reproduce, but they tend to be territorial and solitary," says Simpson.

For information, the octopus in the video is a curly octopus (Eledone cirrhosa) also known as a horn octopus or a small octopus. It has a yellow or red body that is decorated with brown stains like rust. His skin is also shrouded like a wart-like lump.

Like a squid, this species will release dark liquid if it feels threatened. The liquid works to make the water dark and obscures the predator's view. The main foods of this octopus are crustaceans, molluscs, and other invertebrates, including small fish.
