It's unclear whether the creature illustrated is the one discussed at the top of the page - possibly Nymphum coccineum - or Caprella acuminifera, discussed at the bottom of the page. I've listed both in the keywords section but not in the separate species-identifier box.

GailT - its a bit hard to tell because it does not ref fig 7 in the text. (I'd probably read the pages before and after in BHL) but your decision to include both species in the keywords section seems like a good choice. thanks for your thoroughness!
