Hey I want you to look at some Pikeblennies (the genus Chaenopsis). At first they just look like neat long boys:
But then! Look at those big ol’ branchiostegal rays! (Those are the bony rays under the jaw).
And they scream!
So small! So much rage!
Anyway I think they look like little duck-snake-dragon hybrids and I love them very much.
That last two are ‘yelling’ at mirrors. That’s a territorial display meant to impress. They are Very Determined to be impressive.
These photos are great. In addition, a territorial fish that sees a mirror image, flares at the image, and stops seeing the image, like if you take the mirror away, thinks it’s won. It’s probably satisfying as heck for them.
