    That’s a polychaete nematode called Amblyosyllis. I couldn’t find any numbers on typical body sizes, but I found some pictures of it near some ocean-floor pebbles and sand, and my guess is that it grows only 2 or 3 cm long.

    See this is what happens when a Designer mixes up imperial and metric measurements. Now it has metres of feet.

    As always, it is worth clicking the link under the image. There are many more marvels to be seen there. I like the way Fig. 12. Malmgreniella seems to move as I scroll it up and down my window.
