Kind of a low-key episode of Tenchi Souzou Design-bu this week, but enter-cational as always.

• I suppose I should have known what the animal with ribs outside the body was all along, but somehow I didn’t think “turtle” right away.
• To that end, it’s very interesting watching these creatures be built from the ground up.  Effectively, breaking evolution down as if it were a conscious process (which I suppose could be interpreted as a religious viewpoint, though I don’t think it’s intended that way).
• Who knew frogs didn’t have ribs?  And that was my first experience with the poisonous rib-shooting newt.
• Manakin birds?  Likewise new to me.  Heck, I don’t think I even knew what “lekking” was.
• Lekking, by the way, is communal courtship display on a shared “battlefield of love”.
• Was that a seiyuu in-joke with Enoki Junya and the “you seem to know a lot about rap battles?” thing?
• Rap battles as a kind of courtship display is pretty on the money, I have to say.
• That leg thing with the frogs was hilarious.  Edutainment at its best.
• Seals inflating their noses, that I kind of knew.  But I never knew that giant red thing was the septum.  I don’t care what anybody says, that has to hurt.
