Xenopus are pretty amazing creatures when it comes to retaining body fat and surviving starvation. I've seen a lot of stories where these frogs will be abandoned or neglected and still survive for a very long time.

Of course a well fed frog is a much happier and long lived frog but these guys are designed to endure pretty harsh conditions. This of course makes them great pets because when well cared for, they tend to live a long time and do not seem to develop many health issues in my experience.
