Any time a puffer fish is severely frightened it will puff itself up to look larger. "Besides helping to act as a defence against predators, tetrodotoxin resistance has allowed puffer fishes to selectively feed on tetrodotoxin-containing food items which other fishes avoid."

[Strangely enough, the male "gathers" the fine sediments using the circular pattern itself, Kawase said. It is the 20th pufferfish to fall into the species of Torquigener – but it is the only one that creates stunning patterns in the sand to attract a mateOnce finished, the female swims off - never to return.The white-spotted pufferfish is about three-inches long and adorned with white spots on its back and silvery white spots on its abdomen.It is the 20th pufferfish to fall into the species of Torquigener – but it is the only one that creates stunning patterns in the sand to attract a mate.Although the white-spotted fish is the only one of its kind that plays in the sand, there are other species of fish that make similar structures to impress females.Cichlid fish, which live in Lake Malawi, East Africa, build what are known as bowers once or twice a year so they have a place to mate. This is very stressful on the fish. Then, the downstream peaks and valleys funnel the water outward. [Pufferfish mating involves females laying eggs in the fine sediments in the center of the circles, and then the males fertilizing them externally. If they like what they see, they reproduce with the males, said Hiroshi Kawase, the curator of the Coastal Branch of Natural History Museum and Institute in Chiba, Japan.

Finally, the creator of these remarkable formations was found: a newly discovered species of pufferfish. "A" represents the early stage, B the middle stage and C the final stage. Further study showed these small pufferfish make the ornate circles to attract mates.
First, they involve radially aligned ridges and valleys outside the nest site. Some likened these formations to "underwater crop circles." Future US, Inc. 11 West 42nd Street, 15th Floor, Third, the male gathers fine sediments to give the resulting formation a distinctive look and coloring, Kawase said. A fluid dynamics test using a half-size model of one of these circles found that the upstream portion of the circle funnels water and fine sediments toward the center. The body of a puffer fish can swell to over two and a half times its original size as a way to scare off predators. The white-spotted pufferfish was discovered just a few years ago in the waters surround the Amamioshima Island in Japan (pictured)Once the design is finished, a female will swim into the center to signal approval and the male bites on her cheek (pictured) before breeding. The white-pufferfish had laid hidden for centuries, until 1995 when researchers diving off the coast of the Amamioshima Island spotted the delicate patterns etched into the sand on the seabed, Kawase said they likely give up their old formations because the circles exhaust the fine sediment in the area, and thus must be built anew in areas with fresh sediment.When Jordan first heard about the circles, he guessed a much bigger fish would have made them. © D shows the same circle one week after spawning. British researchers from the University of Hull and the University of Nottingham have discovered that the exact shape of the bowers determines how many fights the male fish have with nearby rivals. The geometric formations mysteriously came and went, and for more than a decade, nobody knew what made them. The speed of water was slowed by nearly 25 percent in the center, where the eggs are laid, the study noted.It takes about seven to nine days for the pufferfish to construct the circles. The recently discovered white-spotted pufferfish builds underwater ‘crop circles’ in order to attract a mate, which also doubles as protection for the female’s eggs. One of the circular formations in various stages of completion.
Then, the females vanish, and the males stay for another six days, perhaps to guard the eggs, the study noted.But this new pufferfish's geometric patterns have three features never seen before. but it is $250 cheaper and still get most of the other cutting-edge features found on the more expensive model.AI seems to permeate every part of its software, from the ability to answer calls for you to being able to almost perfectly predict your morning commute.Apple's new iPhone XS and XS Max go on sale on Friday - and the biggest handset Apple has ever made is also its best (and possibly unsurprisingly, its most expensive).Israeli beauty-tech firm Pollogen has launched its Geneo Personal device, which stimulates oxygen from beneath the skin's surface to give you a clearer, fresher face within minutes.Rather than cram in a plethora of new features, Apple's latest update is about boosting stability, with improvements in everything from FaceID and battery life.It's eye-wateringly expensive at $2,999, but Naim's Uniti Atom is a revelation, an integrated amplifier than makes it easy to stream music at a quality you've probably never heard before.Naim's incredible Mu-So Qb takes you back to the good old days - where the music captivates and enthralls, rather that simply being something in the background.Peloton's hi-tech bike lets you stream live and on demand rides to your home - and it's one of the best examples of fitness technology out there - at a price.It might not be a name familiar to the US market, but Naim is a legendary British brand hoping to make a splash with the American launch of its $1499 Mu:So speaker.
