The article says that it's pretty well-established that animals can learn chemical and auditory information before birth. This news is notable because it's the first demonstration of visual information being learned pre-natally. According to the article, the cuttlefish have two advantages on us for this: the obvious advantage of spending their pre-natal time someplace transparent, and the less obvious one of eary ocular development. Human eyes don't really get up to speed until a while after birth.

Basically, my point is very much "Cuttlefish learn about prey as embryos! How badass is that?"
