The members of the family Hemitripteridae are
among the most poorly studied ﬁshes of the World
Ocean. This is especially so in the case of the genus
, in particular,
dan et Gilbert, 1898), a boreal Asian species inhabiting
all Russian Far Eastern seas [1, 3, 4, 11]. In the Sea of
rarely occurs in its southern and
northwestern parts [2, 5, 13]. Information about the
biology, habitats, spawning schedule, and development
of this species is still rather sparse [7, 8, 9, 13].
In this paper we report on the ﬁndings of larvae and
in the western Sea of Japan for
the ﬁrst time and provide their description.
MATERIAL AND METHODS
As the material for this project we used ichthy-
oplankton samples collected in the surface water layer
(0–0.5 m deep) during the nighttime at four stations
located in Peter the Great Bay (see ﬁgure). In Vostok
Bay, at the light Stn. 1, the samples were collected on

—Five specimens of a rare ﬁsh
(12.5, 13.9, 15.0, 33.0 and 54.0 mm SL) were
found in waters of the Far Eastern State Marine Biospheric Nature Reserve and in Vostok Bay. A description of
the examined specimens and habitat data are provided. Literature data and our own observations show that as
the ﬁsh grows from a larva into an adult, the length of the snout and head, as well as the size of the pectoral ﬁn
increase, the eye diameter diminishes, and the pigmentation pattern changes.
