the intended meaning is that the horny jaws play the role of teeth, which is the correct interpretation of 'function as teeth'. i.e., function as teeth --> they work as an acceptable substitute for teeth function as teeth do --> they work in the same way as teeth do - same mechanics, same action, etc. this is not what is meant. 谓语是 function as 起...的作用。
