Kiwa puravida (lat.) Is a species of decapod crustaceans [1] from the genus Kiwa , sometimes called yeti crabs in popular media. Its discovery is recognized as one of the three most important scientific events of 2011 according to a survey of readers of the journal Nature [2] .

The area where Kiwa puravida was discovered in 2006.
A new species was discovered on the seabed at a depth of 1000 m off the coast of Costa Rica at in 2006 by original authors Andrew Thurber, William J. Jones and Kareen Schnabel [1] [3] [4] . Extremities ( pereiopods ) are covered with numerous long bristles. On the first pair of limbs (bearing chelated claws ), symbiotic bacteria develop in large numbers. Perhaps they are grown in order to then be used as food. The crab makes unusual dancing movements with its foremost long legs, swinging them from side to side to enhance the growth of bacterial gardens [5] [6] . Carapax is 1.3 times longer than its width (including rostrum) [1] .
Kiwa puravida became the second species from the previously monotypic genus Kiwa and the Kiwaidae family, in which only the species Kiwa hirsuta Macpherson, Jones et Segonzac, 2006 was found, found on the South Pacific Rise 1,500 km south of Easter Island at a depth of 2200 m [7 ] . The new species differs from the previously known one both according to morphology (the structure of the anterior margin of rostrum and sternites) and molecular genetic (18S rRNA) [1] .
The name of the species K. puravida comes from the Spanish phrase: pura vida - “real life”, as they usually say in Costa Rica, in the waters of which a new taxon was found [1] .
