Do dolphin philosophers talk to each other with earthenware water vessels?

So, I was reading Plato's Gorgias and it suddenly hit me that the word "kratēr" (.coincidence with "crater" much?) can be translated as both "earthenware water vessel" and "a wide mouthed vessel with a large body and a small base". <br><br>Now, it is a known fact that dolphins have a wide mouthed skull with a large body and a small tail. Furthermore, dolphins, like all mammals, do need water to survive; so, one could argue that dolphins live in an "earthenware water vessel" that is the ocean.<br><br>What do you philosophers think?
