Igor (walrus)

Igor (born 1982 or 1983 – 11 April 2013) was a male walrus that lived in the Dolfinarium Harderwijk, where he was also subject of scientific research. He had played international draughts against world champion Ton Sijbrands.[2] Igor also featured in the television show Animal Crackers with Dutch comedian André van Duin.[3] Near the end of his life Igor fell ill, lost the will to eat and suffered from his shoulderjoint.

Subject of research

As well as the other walruses at the Dolfinarium Igor was the subject of scientific research. Igor participated in research concerning the functioning of walrus whiskers. With his whiskers Igor was able to differentiate between circles and triangles and showed this by shaking his head in different ways. Igor was able to recognize the shapes until they reached the size of the tip of a pen. Which showed that walrus whiskers have a similar sense of touch as human fingertips.[3] Another study investigated the effects of drilling for oil and gas on walruses by subjecting Igor to different noises by letting him wear headphones.[5]

gollark: There are two ways around this:- make your "OS" unable to run arbitrary code and instead use a highly limited shell/GUI- sane sandboxing via providing no/a limited FS API to environments where you can run arbitrary code
gollark: The crux of the issue is that people can via a variety of methods write and run code which can edit your thing even if you pointlessly meddle with the shell.
gollark: No.
gollark: Hahahahahahaha.
gollark: Or just get around your awful exact matching easily, use the FS API directly from `lua` or something...
