Stiliger sp. #12
|Maximum size: about 3 mm.
This is a tiny species with sparse, irregularly sized, tuberculate
cerata. It is similar to Stiliger sp. #4
but lacks digestive gland branches in the rhinophores. Diffuse brown
pigment runs along the edges of the foot and rhinophores (more prominent
in larger animals). The tubercles on the cerata are also tipped in brown.
Stiliger sp. #12 is known from six animals found in silty Halimeda
kanaloana beds at depths of about 6-9 m (20-30 ft).
It was first recorded in Hawaii from Maalaea Bay, Maui by PF and CP on May 10, 2008. (Note 1)

Observations and comments:
1: The 2008 animal has fainter brown
markings than the 2014 animals but also lacks branches of the digestive
gland in its rhinophores suggesting that it belongs with this species
rather than Stiliger sp. #4.
