Phyllidia tula is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Phyllidiidae.Bouchet, P. (2015).

Distribution
This species was described from the Ellice Islands, now known as Tuvalu. Brunckhorst examined the type material kept at the US National Museum and additional material from Guam and redescribed the species in greater detail.Brunckhorst D.J. (1993) The systematics and phylogeny of phyllidiid nudibranchs (Doridoidea). Records of the Australian Museum suppl. 16: 1-108. It has also been reported from the Marshall Islands.Johnson S. & Johnson, J., (2016) [http://www.underwaterkwaj.com/nudi/porostomes/e411.htm Phyllidia tula Marcus & Marcus, 1970] Underwater Kwajalein.
Description
This nudibranch has a black dorsum with large yellow-capped tubercles surrounded by pale blue or translucent white rings. Towards the edge of the mantle these tubercles become small and scattered, sometimes without any yellow caps. The rhinophores are yellow or orange. A distinctive feature is the presence of small, yellow-capped, tubercles at the edges of some of the large tubercles in the middle of the back, and scattered smaller tubercles between the larger ones. The underside of the foot is grey with a longitudinal black line. It is very similar to Phyllidia carlsonhoffi and Phyllidia madangensis.Rudman, W.B., 1999 (January 12) [http://www.seaslugforum.net/find/phyltula Phyllidia tula Marcus & Marcus, 1970.]
Diet
