Arrow worm (Chaetognatha). Bristle worm (Polychaeta)

Post by Charles Krebs »

The first shot is likely the last thing a lot of small marine planktonic copepods see before the Arrow worm grabs it with those bristles on either side of the head, and then its down the gaping mouth. I posted a few shots of another arrow worm couple weeks ago, but did not get any shots of the ominous looking grasping spines. Netted a few more, so I was able to get some more images... and a cute little bristle worm as a bonus.

Charles,

Very nice, the grasping spines details and the dark field image are amazing.
