    Just a passing curiosity. Wikipedia's article on Hemolymph [here] says that some arthropods have hemolymph. I was under the impression that all arthropods have hemolymph. Can anyone clear this up? Have any examples of arthropods w/o hemolymph? Thanks!

    The wiki article also says "even some insects..." as if it's a shock to observe haemolymph in insects, giving the impression that most insects don't in fact have haemolymph.

    I thought I would clean up that article a bit, but I'll need to find some decent sources first. Apparently it has been years since someone on the Talk page noted the article has problems, but no one has stepped forward. If only I still had access to my old school library!

    UPDATE: I posted a question over at Ask A Biologist. We'll see if someone responds.

    UPDATE: Been a week and no response from that site. Maybe they are just slow to respond? At any rate I'm now hunting around for an informed zoologist with a specialty in sea life. :P

    UPDATE: from ask a biologist (see link in above post):

    You are correct, all arthropods (and some molluscs) have haemolymph, the blood-like fluid which circulates through the body cavity (or haemocoel). Wikipedia is a great resource, but anyone can contribute to it, so sometimes it contains inaccuracies. Over time these get cleaned up when someone notices the error.

    I slightly modified the wiki article wording, but I encourage anyone who knows more about it to add to the modification.
