WARNING: The gallery above contains graphic images of animal carcasses after death and dissection.
See what's under the skin of a giant squid, a giraffe and a bull as the Canadian Museum of Nature hosts the Animal Inside Out exhibit.
The unique anatomy lesson, which includes more than 100 animal specimens, is created by Body Worlds, which has toured the world with its exhibition of real human bodies that have been preserved through plastination.
The process replaces water and soluble fat with a reactive polymer, such as silicone rubber.
The exhibition, which includes one preserved human body, is in Ottawa from May 1 to September 20.
