Photograph of a pregnant uterus (womb) from a New Forest pony, approximately five months into the pregnancy.

Photograph of a pregnant uterus (womb) from a New Forest pony, approximately five months into the pregnancy.

The developing pony (fetus) is outside the uterus but remains attached by its membranes and umbilical cord. The bent back legs of the fetus are sticking out from the membranes (top right-hand side). The uterus has been cut open to reveal its vast blood supply, which is visible on the inner surface.

This historical specimen is from a cull animal that happened to be pregnant at the time. It is preserved in formalin in a Perspex container and was photographed in the Anatomy Museum of the Royal Veterinary College in London. The container measures 48 x 30 x 7 cm.
