Sea robins are fish with ‘the wings of a bird and multiple legs like a crab’

Some types of sea robins, a peculiar bottom-dwelling ocean fish, use taste bud-covered legs to sense and dig up prey along the seafloor, according to new research.
Sea robins are so adept at rooting out prey as they walk along the ocean floor on their six leglike appendages that other fish follow them around in the hope of snagging some freshly uncovered prey themselves, said the authors of two new studies published Thursday in the journal Current Biology.
David Kingsley, coauthor of both studies, first came across the fish in the summer of 2016 after giving a seminar at the Marine Biological Laboratory in Woods Hole, Massachusetts. Kingsley is the Rudy J. and Daphne Donohue Munzer Professor in the department of developmental biology at Stanford University’s School of Medicine.
Before leaving to catch a flight, Kingsley stopped at a small public aquarium, where he spied sea robins and their delicate fins, which resemble the feathery wings of a bird, as well as leglike appendages.
“The sea robins on display completely spun my head around because they had the body of a fish, the wings of a bird, and multiple legs like a crab,” Kingsley said in an email.
“I’d never seen a fish that looked like it was made of body parts from many different types of animals.”
Kingsley and his colleagues decided to study sea robins in a lab setting, uncovering a wealth of surprises, including the differences between sea robin species and the genetics responsible for their unusual traits, such as leglike fins that have evolved so that they largely function as sensory organs.
The findings of the study team’s new research show how evolution leads to complex adaptations in specific environments, such as the ability of sea robins to be able to “taste” prey using their quickly scurrying and highly sensitive appendages.

The magical white stone wonderland with effervescent bathing pools

From a distance, Pamukkale looks every bit like a ski resort, with a cascade of brilliant white slopes and a scattering of tourists at the top, seemingly preparing to slalom down into the valley below.
So why isn’t it melting away as midsummer temperatures nudge toward 100 Fahrenheit, or 37 Celsius, and the heat hangs in the shimmering air?
Because this unusual and beautiful wonder, located deep in the sunkissed hills of southwestern Turkey, isn’t snow at all. In fact the water it’s formed from sometimes spurts out of the ground at boiling point.
And those visitors milling around its upper reaches aren’t going anywhere fast. Most are here to take in the extraordinary spectacle – and either paddle or soak in some of the planet’s most photogenic pools.
Today, Pamukkale’s travertine limestone slopes and pools, filled with milky blue mineral water, are perfect for Instagram moments, especially as the magic hour evening sun casts their rippled surfaces in hues of pink.
Gateway to Hell
But this place was a tourist sensation thousands of years before social media, as first Greeks, then Romans flocked here for the thermal waters and to pay tribute at what was revered as a gateway to Hell.
Today, Pamukkale and the ancient city of Hierapolis, which sprawls across the plateau above the white terraces, are part of a UNESCO World Heritage site that pulls in coachloads of visitors. Typically, many visit for a couple of hours, but it’s worth spending at least a day in this geological and historical playground.
