definately cetacean penis. And (I'm not good at this) that which appears to be a

---edit---

 

Right Whale maybe?

More info here, though the paper isn't out yet

Maybe something's wrong with me, but I couldn't imagine anything else it would've been, considering the change in colors and texture and the obvious bulk.

yup, definately Mobys Dick
