Hancockia sp. #1
Maximum size: 6 mm.
Identification:
This
animal is translucent tan with a dusting of tiny white flecks on
the body, cerata and rhinophoral sheaths. There are
a handful of irregularly-shaped opaque white spots scattered over the
body and a single circular opaque white spot on the posterior base of
each rhinophoral sheath and on the inner base of each ceras.
There are five pairs of cerata which branch into hand-shaped
groups of finger-like processes facing outward. The first pair is
directly opposite and the remaining four become progressively less
directly paired. The rhinophores are tipped with brown and white and
are
retractile within sheaths which have papillate margins. The velar lobes
have three or possibly four finger-like processes of varying lengths.
Ducts from the liver can be seen as two lines running anteriorly from
behind the first pair of dorsal lobes to the base of and up to the top
of the rhinophoral sheaths as well as extending posteriorly to the
cerata.
Natural history:
Hancockia sp. #1
