Scientific Name	Common Name	Summary
Aplidium californicum	Sea Pork	This species is found on rocks in the low intertidal, subtidally, and growing on floating man-made structures. The main diagnostic criterion is the colony's general look and feel which reminds one of pork fat. Within this tunic, zooids can be found which are generally yellow, orange, or tan.
Aplidium coei		This tunicate was found subtidally by Ritter in 1901 in Kodiak, where he found it to be common, and again on Kodiak by Gretchen Lambert a hundred years later - in the low intertidal. Catie Bursch also found it in Kachemak Bay. In our area found in Scow Bay near Sitka in spring 2011, in the shallow subtidal. While there are apparently no other records, the small amount of tunicate data in our region suggests that there is no reason to think that this is a rare species.
Synoicum pulmonaria		In the Pacific Ocean and Bering Sea, the species Synoicum pulmonaria and its closely related taxa are known from very few collections. We know only one collection in our area: a specimen collected in Whiting Harbor in April 2011 falls under that species, but it may be re-assigned to an as-yet undescribed taxon if the genus is revised. Macroscopically, this Ascidian colony is globulous, about 3.5 centimeters tall and five centimeters across, with a short wide base. The tunic is transluccent and light orange, and the zooids a more intense reddish orange, and organized in systems of about seven zooids with a communal central excurrent siphon.
