Probably just about anyone on the list can spot a goof in a summary
article in the latest Science.  The article is about the increasing
use of large numbers of sequences in phylogeny analyses.  Although
it's inspired mainly by an article about birds in the same number of
Science, it also refers to a study recently published in Nature in
which a large suite of animals was studied.  One result of that study
was support for the mollusks as a coherent group, something that has
been elusive in previous molecular studies.  To illustrate this, they
included a photo of a mollusk, but it's not a nudibranch, contrary to
the picture caption!  If you want to see if you know more about shells
than the editors of Science, here's the reference:

If you don't have ready access to Science, the animal is roughly an
elongate oval, with rounded ends.  There's a ridge across the middle
(transverse, the narrower dimension).  It has large squarish orange
blotches with dark brown edging and a pale peach-colored background
and is on a gorgonian.  No tentacles or other projections are visible
in the dorsal view.
