Would you rather have a Husk with Cthulhu-esque tentacles for mouth? Devs said they weren't sure how exactly the Protheans would look when they made the first Mass Effect. The squadmate looks similar to a Collector because the Reapers did a -rewrite- of the Prothean DNA, not created completely new strain. So obviously some similarities remained.
