today's invertebrate............malleus malleus
why? why is malleus malleus shaped like that?? she looks like cow tools! or like a weird piece of driftwood. or a bipalium. a little bit like a hammer too. maybe that's why they call her the hammer oyster? probably not. she looks more like a prounch than any hammer I've seen before

the elongated hinges on this bivalve help to anchor it to the sediment and prevent it from sinking in it!
