Irene Bernasconi
Irene Bernasconi (29 September 1896 – 7 July 1989) was an Argentine marine biologist specializing in echinoderm research and best known for her work in the Antarctic. She was the first echinoderm specialist in Argentina and spent 55 years conducting research into echinoderms found in the Argentine Sea. Her main focus was sea stars; however, she also conducted research into brittle stars and sea urchins. Work Over the course of her career, Bernasconi described a number of new genera and species. Her first taxonomic publication, in which new species from the genus '' Pteraster'' were described, was published in 1935. In 1941 she described two new species from the genus '' Luidia''. Between 1937 and 1980, Bernasconi revised the taxonomy of a number of families: Pterasteridae, Luidiidae, Odontasteridae, Gonisasteridae, Ganeriidae, Asterinidae and Echinasteridae. In 1965 she described the new genus of '' Vemaster'' along with four new species. Bernasconi was one of the firs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Echinasteridae
The Echinasteridae are a family of starfish in the monotypic order Spinulosida. The family includes eight genera and about 133 species found on the seabed in various habitats around the world. Taxonomy Echinasteridae contains eight genera and about 133 species. The two genera '' Echinaster'' and ''Henricia'' are the most speciose, forming species complexes. ''Echinaster'' has a largely tropical distribution and occurs in shallow seas including continental shelves, while ''Henricia'' is cosmopolitan, occurring mostly in cold waters, including polar habitats and abyssal locations. '' Aleutihenricia'' and '' Odontohenricia'' are native to the northeastern Pacific Ocean, in the vicinity of the Aleutian Islands. Characteristics Echinasterids are mostly five-armed starfish with thick but small discs, and long, slender, often cylindrical arms. The cuticle is covered on both the aboral (upper) and oral (lower) surfaces by a latticework of ossicles which are either flattened or rounded ...

Google Doodle
A Google Doodle is a special, temporary alteration of the logo on Google's homepages intended to commemorate holidays, events, achievements, and notable historical figures. The first Google Doodle honored the 1998 edition of the long-running annual Burning Man event in Black Rock City, Nevada, and was designed by co-founders Larry Page and Sergey Brin to notify users of their absence in case the servers crashed. Early Marketing employee Susan Wojcicki then spearheaded subsequent Doodles, including an alien landing on Google and additional custom logos for major holidays. Google Doodles were designed by an outside contractor until 2000, when Page and Brin asked public relations officer Dennis Hwang to design a logo for Bastille Day. Since then, a team of employees called "Doodlers" have organized and published the Doodles. Initially, Doodles were neither animated nor hyperlinked—they were simply images with tooltips describing the subject or expressing a holiday greeting. D ...
