An international team of researchers analyzed the amphioxus, also known as lancelet
- a living fossil, of sorts, that was long considered to be a faceless and brainless fish.
Presence of phenoloxidase and prophenoloxidase in the epidermal cells and the epidermis mucus of the lancelet
Branchiostoma belcheri tsingtauense.
A new species of lancelet
, Branchiostoma longirostrum (order Amphioxi), from the western North Atlantic.

Such a scenario would also explain why the lancelet
amphioxus, a 'primitive' chordate, has a notochord with both cartilage and muscle.
A group of 15 species included flatworms, nemerteans, two sipunculans, oligochaetes, two brachiopods, two echinoderms, hemichordates, a lancelet
and a gobiid fish (Vargas 1989).
I have my doubts about how much "puzzling" compositors went in for, since the instability of speech-prefixes in this instance is matched by an even greater instability in another play printed in Quarto in 1600 by James Roberts, not Valentine Simmes, The Merchant of Venice, where Lancelet
appears variously as abbreviations of that name and "Clown," and where Shylock occasionally appears as "Iewe.
These early ancestors of man, thus seen in the dim recesses of time, must have been as simply, or even still more simply organized than the lancelet
They are now convinced the 2in-long Florida lancelet
anchovy, which has hardly changed in more than 500million years, is descended from the earliest chordates, the group from which we are all descended.
The lowly lancelet
makes a living by burying itself in the sand, sticking out its mouth, and filtering tiny critters from seawater.
Last year, the Lancelet
published a study by a team from John Hopkins University and the National Cancer Institute that found a strong correlation between blood PCB levels and the risk of non-Hodgkins lymphoma in the general population of Washington County, Md.
It is regarded as one of the top five general medical journals in the world - the others being the New England Journal of Medicine, Journal of the American Medical Association, The Lancelet
and the British Medical Journal.
