We describe a new species of the bizarre crinoid Tiaracrinus, T. jeanlemenni sp. nov. It is extremely tough to determine whether a species is extinct, or simply absent from an area – but you do only want one specimen to show that a species continues to be with us. Fortuitously, there have been a number of situations of species that had been considered extinct (generally for thousands and thousands of years) being rediscovered.
The IUCN highlight the momentous efforts being taken by New Zealand to convey two species of kiwi back from the precipice of extinction Both the Okarito kiwi and the northern brown kiwi have been downgraded from endangered to susceptible, after intensive predator control on offshore islands have helped boost their numbers.
This yr, too, scientists found and described several thousand new species of animals and crops, together with 13 new dancing peacock spiders, a brand new crab that was present in a pet market, a new species of whale, a tarantula that shoots balls of barbed hair at enemies, and one fowl that is now 13 distinct species.
It differs from the beforehand known species in the increased variety of ribs and the vaulted rib-fields, which is corroborated by the comparability of easy quantitative characters and ratios as well as by the results of a cluster analysis and a PCA.
