The ancient predator's eyes likely mirror the smaller and much simpler eyes of modern-day tardigrades
and velvet worms, (http://www.sciencemag.org/news/2018/03/ancestor-today-s-insects-spiders-and-crustaceans-had-simple-brain-complex-eyes) Science reported.
Study coauthor Kazuharu Arakawa from Institute for Advanced Biosciences, Keio University, in Japan, said in (https://www.eurekalert.org/pub_releases/2018-02/p-nts022218.php) a statement Wednesday: "We revisit the large and long-standing Macrobiotus hufelandi group of tardigrades
, originally described by Schultze in 1834 and where M.
are known to survive incredible conditions.
The founder of the Arch Mission Foundation, Nova Spivack, told the magazine that their cargo aboard Beresheet, a few thousand tardigrades
planned for biological experiments, could be 'the only surviving thing from that mission.'
Arch Mission Foundation boss Nova Spivack said: "We believe the chances of survival for the tardigrades
are extremely high."
Based on an analysis of the spacecraft's trajectory and the composition of the device the micro-animals were stored in, "we believe the chances of survival for the tardigrades
...are extremely high," Nova Spivack, founder of the Arch Mission Foundation, told AFP.
Ten plenary presentations and four flash talks were given, structured into five sessions, "Cellular methods", "Reconstitution and 3D printing", "Applications", "Ex ovo models and chronic diseases", and "Organisms (Caenorhabditis elegans and tardigrades
) as models".
Analysis of the opsin repertoire in the tardigrade
Hypsibius dujardini provides insights into the evolution of opsin genes in Panarthropoda.
Remember that story about the tardigrade
genome being about 17% foreign DNA?
specimens were identified using keys in Ramazzotti and Maucci (1983), Nelson and McInnes (2002), and Pilato and Binda (2010), and by reference to original descriptions.
Later sections cover protozoa to tardigrade
, phylum Mollusca, phylum Annelida, and phylum Athropoda.
In its desiccated form, the tardigrade
performs some life-saving functions.
