Cyanoplax dentiens (Gould, 1846)
Gould's Baby Chiton *
intertidal to 6m          northern Mexico to southern Alaska          size to 2.7cm
This is a common intertidal species although often hard to spot due to its small size.  It is variable in color but is most commonly greenish-gray to brown.  White flecks or blue-green dots are also typical.
(previous names - Lepidochitona dentiens, Ischnochiton dentiens)

Cyanoplax fernaldi (Eernisse, 1986)
Fernald's Baby Chiton
mid to high intertidal          southern Oregon to SE Alaska          size to 15mm
This species is hard to find due to its small size.  Its preferred habitat is among Thatched Barnacles and Aggregating Anemone, where it is tucked into crevasses where it is not easily seen.  This species is easy to confuse with C. dentiens although it usually has more eroded plates.  Our left photo shows a rare turquoise phase.

  Schizoplax brandtii (Middendorff, 1847)
very low intertidal to 40m          central BC to Alaska, Bering Sea & Sea of Japan          size to 2cm
This is occasionally seen intertidally.   It has brown striping over a blue background.  The plates are split down the mid-line by cartilage-like tissue which is best seen under magnification.  There may actually be more than one species represented across its range.
