GODDARD ET AL.: EL NINO IMPACT ON HETEROBRANCH SEA SLUG RANGES 115 
imens (CASIZ 216866, 209506, 209501), 5 June 2016 (observed by JG and NT; for image see 
< http://www.inaturalist.org/observations/3528069 >); 1 specimen, 27 May 2017 (observed by NT). 
Crook Point, Curry Co., Oregon, 2 specimens, low rocky intertidal, 7 February 2016 (observed by 
NT). 
Remarks: Goddard et al. (2016) reported finding a single juvenile D.fulva at Whiskey Creek, 
Oregon in June 2015, the first specimen of this species reported from north of California. One year 
later (6 June 2016) at the same site JG and NT counted 43 specimens of D.fulva, and a year after 
that (29 May 2017) NT found 11 specimens. For the southern Oregon coast as a whole, only two 
specimens of D.fulva were found in 2015 (Goddard et al. 2016). This was based on 37 trips to 20 
sites, largely by NT. The following year NT counted a total of 204 individuals in 19 visits to 13 of 
those same sites, finding D.fulva at seven of them. Through the first half of 2017 NT had counted 
24 total individuals of D.fulva at four out of 10 sites visited in southern Oregon. Todd Cliff and 
Andy Lamb found at least 5 specimens in Netarts Bay on 5 June 2017 (Todd Cliff, personal com¬ 
munication to JG, 25 June 2017). 
Doriopsilla gemela Gosliner, Schaefer and Millen, 1999. Elkhom Slough, Moss Landing, 
California, 1 specimen, 4 m depth, just inside entrance to slough, 5 July 2016 (Bentall 2016) to 
Bahia Tortugas, Baja California Sur (Bertsch and Aguilar Rosas (2016). 
Previous northernmost locality: Monterey, California (Hoover et al. 2015; Goddard et al. 
2016; and see <https://www.inaturalist.org/observations/5220737>). 
Additional northern localities: T Pier, Morro Bay, California, 19 specimens with egg masses 
on shell rubble, 3^1 m depth, 25 May 2016 (observed by CH). 
Tritonidae 
Tritonia myrakeenae Bertsch and Mozqueira, 1986. Estero Bluffs State Park, San Luis Obis¬ 
po Co., California, 3 specimens, among the octocoral Clavularia sp. under low intertidal cobbles, 
29 April 2017 (observed by JG; for image see <https://www.inaturalist.org/observa- 
tions/6358562> ) to Costa Rica and Panama (Camacho-Garcia et al. 2005). 
Previous northernmost locality: Santa Barbara, California (Behrens 1980). 
Additional northern localities: Cave Landing, San Luis Obispo Co., 4 specimens, 27 May 
2013; 1 specimen, 8 October 2014; 1 specimen, 9 March 2016 (observed by JG); Tarantula Reef, 
Jalama Beach, Santa Barbara Co., 1 specimen, 5 July 2012; 1 specimen, 2 February 2015 (observed 
by JG); Gaviota, Santa Barbara Co., 6 specimens, 7 May 2012 (observed by JG); Naples, Santa 
Barbara Co., 1186 specimens, October 2006 - April 2017 (observed by JG). 
Remarks: This diminutive tritonid, which has been by far the most abundant nudibranch at 
Naples, is usually found associated with the stoloniferous octocoral Clavularia sp., on whose 
polyps it preys (for image see <https://www.inaturalist.org/observations/5396758>). 
Dotoidae 
Doto lancei Ev. Marcus and Er. Marcus, 1967. Dana Point Harbor, California, 1 specimen, 
18 November 2017 (Stacey 2017) to Panama (Hermosillo 2004). 
Previous northernmost locality: Mission Bay, San Diego, California (Behrens 1991). 
Remarks: Behrens (2004) reported D. lancei from Monterey Bay, but without an image to 
confirm the identification, we suspect it was actually D. columbiana O’Donoghue, 1921, which is 
common in central and northern California and superficially resembles light colored D. lancei but 
has shorter ceratal tubercles lacking the apical spots characteristic of D. lancei.
