Otterbox iPhone cases are widely considered to be some of the best on the market. They protect against dust, scratches, and shattering, but, unfortunately, not against otters themselves.

An otter at the Red River Zoo in Fargo recently found himself the owner of a brand-new iPhone when a spectator dropped it into the exhibit. Though the Otterbox name might suggest otherwise, the case was not a problem for the real otter, who ripped it apart, dropped the phone in the water, retrieved it so he could chew on it, then dropped it in the water again.

Which start-up will be the first to fill this technical void and create otter-proof phone cases?
