    Of course, this being Ozland, the crab is not one of the safe sheep, “‘The sponge isn’t just a disguise, as they are well known for having a very good set of chemical defences to protect themselves from predation. Many produce toxins or otherwise obnoxious chemicals to deter predators […]’ [explained Andrew Hosie, curator of Crustacea at the WA Museum]” (from the article linked-to in the OP).

    The mildly deranged penguin points out the alleged crab and its “toxins or otherwise obnoxious chemicals” is just an unripe mobile cheese. You can tell it’s unripe as the divers remains on the top hasn’t been fully digested, and has gone all moldy. Ripe mobile cheeses are much more efficient diners than that.
