Muny pre(liLtors probably cat, t.ho 8hrirnps by accident in the midwater
luyer ritther than by design, cutahing them along with more important
food orgunisnis. Yauiphac?a mul/identata along with two species of the
genus Panrlalus comprised 9 to 27% by volume of food of the redfish
Sehastes marinus (linnaeu.us) in the Gulf of St. Lawrence (Steele, 1957).
According to Ptixton (1 987), who examined stomach contents of myctophids from California, of 139 specimens of Stenobruchius leucopsarw
(Eigenmann and Eigenmunn), Lumpanyctus ritteri Gilbert, Ceratoscopelus townsendi (Eigenmann and Eigenmann) and Lampadena urophws Paxton, twenty had eaten sergestids. Some of other fish feeding
on the shrimps are the New Zealund groper Polyprion oxygeneios (Bloch
et Schneider) (as 1’. prognathus) on Oplophorus novaezeelandiae de Man
(de Man, 1931), the anglemouth Gonostoma elongaturn Giinther on
Acanthephym purpurea (Chace, 1 940), Polyprion oxygeneios and the ling
Genypterm blacodes (Bloch et Schneider) on Sergia potens Burkenroad
(Yaldwyn, I957), Thunnus albacares on Sergia gardineri (Alverson, 1963)
and Funchalia woodwardi Johnson (Penrith, 1963-cited by Dragovich,
1969), and the lancetfish Alepisaurus ferox Lowe on Sergia lucens (Kubota and Uyeno, 1970). Figueira (1957) reported the occurrence of
Pnsiphaeci hplocrrca Chuco, P . multidentata, Oplophorm spinosus, Acanthephyra curtirostris, A . eximia, Ephyrina hoskyii Wood-Mason, Systellaspis crisiata ilnd 8. debilis together with two species of Heterocarpus
from tho stoni;ichs of the scabbard fiHh Aphanopus carbo Lowe which
were caught from about 600 to I 000 m depth on long lines by Madeiran
fishermen. Luttr, Eupaaiphae gilesi m d Acantkphyra purpurea were
also found from the stomiichs of the mme fish (PiHher und Ooldie, 1961 ;
]%her. and Kon, 1959). Mr 1’. Sasiiki gave me un opportunity to examine
the stomtrc ti contents of the pelagic srmorhead Pentaceroa richarhoni
Stnitli whicuh were aolloctcd by RV “Kuiyo Maru” from the Milwaukee
Seamounts. west of the Midway IsImdN, in I)ccember 1972. ConsideriLbk numbers of Sergestes artrmlus were found together with thc
euphuusiid Thyllsanopoda monacanthn Ortmann and the myctophid
Louwinn rnra (Liitken). The blue white dolphin Stenella caeruleoalba
(Meyeii) preft*rably eats Hentheouennema borealis together with Pusiphnea sp. and Acccnthephya sp. in Sagami Bay, Japan (Miyrtzaki et al.,
1973). Thew are interesting records showing that Pasiphaea longispinu
W ~ L H found from the stomachs of the Emperor penguin ilptenodytes
forsteri Gray anti the mow petrel Pagodrorna nivea (Forskr) in the
antarctic region (Lciiz and Strunck, 1914; Hale, 1941).
