The chiton (in the center of the photo) is a Veiled Chiton (Placiphorella velata). It might be difficult to spot at first, but it's nestled next to an Aggregating Anemone (Anthopleura elegantissima).
Below is a side view of the chiton where can see how the setae (bristles) at the head end look similar to the tentacles of the anemone:
Placiphorella is an unusual chiton. While most chitons are grazers, this species is predatory. It raises its veil (as in the photo below), waits for prey to pass underneath, and then clamps down quickly to capture it. The bristles above probably help to camouflage the chiton, making it harder for prey to recognize a possible predator.
I first introduced Veiled Chitons back in 2012 (was it really that long ago?). If you'd like to learn more about them, check out the post called "A veiled threat" from 21 August 2012.
Wow, predatory chiton! It can be difficult to discern what I am looking at, especially at first. The diagram in your post from 2012 helped.
ReplyDeleteThanks for linking to your related posts - that is really helpful for the uninitiated.
Such great content, Jackie, thanks for teaching us!!
Hi! Yes, I realized it might be tough to locate the chiton in that first photo. I'm glad the older post with the diagram was helpful!
