Igor (born 1982 or 1983 – 11 April 2013) was a male walrus that lived in the Dolfinarium Harderwijk in the Netherlands, where he was also subject of scientific research.
[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 shoulder joint.
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 touch sensitivity 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.
