Abstract. Heterotopic gastric mucosa of peculiar shape and located in the duodenum bore a close resemblance to superficial ulcerating cancer. Radiographic survey showed a flexible lesion with a mucosal pattern resembling area gastrica. Endoscopy revealed its color to be indistinguishable from that of the normal duodenal mucosa.
The smaller species of hedgehog usually live for 2 to 4 years, and the larger species can live for up to 7 years in the wild. In captivity, hedgehogs tend to live for longer. This is due to the fact that they donât have any predators and always have access to food. Some captive hedgehogs have reached the age of ten.
Hedgehogs are native to mainland Britain and are also found throughout northern and western Europe. Related and similar species are also found as far as north Africa, the Middle East and central Asia. There are 16 species of hedgehog in five genera, found through parts of Europe, Asia, Africa and New Zealand. 1  There are no hedgehogs native to Australia and no living species native to North America. 2  The pre-breeding season population estimate of Hedgehogs in Britain is around 1,555,000.
