Eumicrotremus asperrimus (Tanaka, 1912). Siberian Lumpsucker. To 13.5 cm (5.3 in) TL (Mecklenburg et
al. 2002). Japan and Okhotsk seas and Pacific Ocean off Hokkaido to western Bering Sea at Natalia Bay,
Koryak coast (61°10'N; Andriashev 1937, Lindberg and Legeza 1955) to Pacific Ocean south of Unimak
Island, Aleutian Islands (Mecklenburg and Sheiko 2003). At depths of 30–900 m (99–2,970 ft); juveniles
usually shallower than 100 m (330 ft; Mecklenburg et al. 2002). Until recently went by the name of
Eumicrotremus birulai Popov, 1928, which is now recognized as a junior synonym (Mecklenburg and
Sheiko 2003).
Eumicrotremus barbatus (Lindberg & Legeza, 1955). Papillose Lumpsucker. To 7.0 cm (2.8 in) TL (UW
49408). Sea of Okhotsk off Hokkaido, Japan (Kido 1984); Pacific Ocean off Paramushir Island, Kuril
Islands (Lindberg and Legeza 1955); and Aleutian Islands from Near Islands (UW 49414) to south of
Unimak Island (UW 42943; Mecklenburg and Sheiko 2003). “At the shore” (Ueno 1970) to depth of
210 m (693 ft; Kido 1984).
Eumicrotremus derjugini Popov, 1926. Leatherfin Lumpsucker. To 12.7 cm (5 in) TL (Mecklenburg et
al. 2002). Isolated population in northern Sea of Okhotsk; most Arctic seas, including Beaufort Sea
(Mecklenburg et al. 2002) and East Siberian Sea, but not Chukchi Sea (Mecklenburg and Sheiko 2003).
Not confirmed from Labrador; the specimen (USNM 105009) reported from there by authors (e.g.,
Scott and Scott 1988) is Eumicrotremus eggvinii (not a West Coast species; Mecklenburg and Sheiko
2003). At depths of 50–930 m (165–3,069 ft) (min.: Andriashev 1954; max.: Jensen 1944).
Eumicrotremus gyrinops (Garman, 1892). Alaskan Lumpsucker. To 3.75 cm (1.5 in) SL. Southeastern
Bering Sea off St. Paul Island, Pribilof Islands. Shallow water. All in Mecklenburg et al. (2002). Known
with certainty only from the holotype; possibly the senior synonym of E. phrynoides (Mecklenburg and
Sheiko 2003).
Eumicrotremus orbis (Günther, 1861). Pacific Spiny Lumpsucker. To 12.7 cm (5 in) TL (Mecklenburg et al.
2002). Pacific coast of Hokkaido, Japan to Bering Sea and to Puget Sound, Washington (Mecklenburg
and Sheiko 2003). Shallow water, at 2 m (6.6 ft) or less (Miller et al. 1980), to 359 m (1,178 ft; UW 46668);
reported as deep as 575 m (1,898 ft; Allen and Smith 1988). Many specimens previously recorded in the
literature as E. orbis were misidentified, including those from Okhotsk Sea, Kuril Islands, Pacific Ocean
off southeastern Kamchatka, Russia; and northeastern Bering Sea, Alaska (Mecklenburg and Sheiko
2003).
Eumicrotremus phrynoides Gilbert & Burke, 1912. Toad Lumpsucker. To 7.4 cm (2.9 in) TL (Mecklenburg et
al. 2002). Near Strait (52°59'N, 172°19'E; UW 49601), Aleutian Islands and southeastern Bering Sea near
Pribilof Islands (USNM 53807; Mecklenburg and Sheiko 2003) to northern Gulf of Alaska (59°54'N,
148°02'W; Mecklenburg et al. 2002). At depths of 69–235 m (228–771 ft) (min.: Mecklenburg et al.
2002; max.: UW 111314). Possibly a junior synonym of E. gyrinops (Mecklenburg and Sheiko 2003).
Cyclopteropsis inarmatus Mednikov & Prokhorov, 1956, may be a junior synonym, and if this is the
case the species is known also from western Bering Sea (Glubokaya Bight, Koryak coast, 60°50'N; B. A.
Sheiko and C. W. M., unpubl. data).
Eumicrotremus soldatovi Popov, 1930. Soldatov’s Lumpsucker. To about 26 cm (10.2 in) TL (Mecklenburg
et al. 2002). Northern Okhotsk Sea and North Pacific Ocean off southeastern Kamchatka (Mecklenburg
and Sheiko 2003); one record from Bering Sea, Alaska near northwest end of Bowers Ridge (Ueno 1970).
Pelagic; at depths of 80–350 m (262–1,148 ft; Orlov 1994).
*Eumicrotremus spinosus (Fabricius, 1776). Atlantic Spiny Lumpsucker. To 13.3 cm (5.25 in) TL. Length of
13.7 cm (5.4 in) previously reported from Jensen (1944), who cited Fabricius’s original description for
dried specimens measuring “5 1/4 inches (= 137 mm).” However, 5.25 inches = 133 mm. Andriashev
(1954) reported a maximum length of 13.2 cm (5.2 in). Any of those lengths could be less, due to
