A 150 million-year-old marine invertebrate unearthed in Africa has been named after Ukraine’s President Volodymyr Zelensky.
The weird creature had 10 lengthy arms and sharp tentacle-like claws to grip the seabed.
It was a kind of feather star, that are plentiful in the present day on rocky bottoms from the Equator to the poles.
Ausichicrinites zelenskyyi is carefully associated to sea stars, sea cucumbers, and sea urchins.

“The fossil is very preserved,” stated lead writer Professor Mariusz Salamon, of the College of Silesia, Katowice, Poland, stated.
“Ausichicrinites zelenskyyi had 10 large arms and a hoop of claw-like appendages close to the bottom to grip the substrate.”
He added: “The animal lived 150 million years in the past – and reveals putative traces of arm actions.
“It has been named in honor of Volodymyr Oleksandrovych Zelensky, the sixth and present president of Ukraine, for his braveness and bravado in defending free Ukraine.”
Feather stars may be quite a lot of spectacular colours, from deep reds to vibrant oranges and electrifying yellows. Every arm may be as much as a foot lengthy.
Their appendages are used to catch meals, making the animals filter feeders. They sit within the water, expose their arms, and let vitamins moved by the present come to them.
Feather stars even have the flexibility to shed an arm the best way some lizards can their tails, which can be an anti-predator response.
Salamon stated: “The specimen reveals proof of regeneration, which reinforces the speculation in regards to the significance of predation within the evolution of feather stars.”
Ausichicrinites zelenskyyi was about 2 inches in diameter. Its nearly full stays have been dug up at a web site in central western Ethiopia.
“Feather stars, or comatulids, are largely recognized from extremely disarticulated specimens,” Salamon stated.
“Right here, we report an almost full, and thus extraordinarily uncommon, comatulid from the Higher Jurassic of the Blue Nile Basin in central western Ethiopia that gives a novel perception into the morphology of comatulid arms and claws.”
He added: “The brand new fossil from Africa constitutes the earliest, the primary instance of regeneration in a feather star.”
Born with a stem that they shed in maturity, feather stars can have as few as 5 arms and as many as 200.
They’re typically conspicuous to divers and snorkelers. They aren’t toxic to people, however may be poisonous to different animals.
Snails typically reside on them. Fish might comb by feather stars on the lookout for a tasty meal.
Feather stars are echinoderms, just like the extra acquainted sea stars. They’re additionally a kind of crinoid, together with sea lilies, which have a stalk.
Ausichicrinites zelenskyyi is described within the Royal Society journal Open Science.
