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.
As such, the male does not have to get completely on top of the female when mating. Depending on the species, the gestation period is 35 â 58 days. The average litter is 4 â 7 newborns for larger species of hedgehog and 5 â 6 for smaller ones. The pale-coloured soft spines appear hours after birth and take 3 weeks to harden. Hedgehogs are born blind. Many believe that they are born without quills, which develop in the following days.
