(BHL),
a rover Plagiogeneion
geminatum
(BHL),
and
a lefteye flounder Parabothus
amaokai (ResearchGate).
Deep sea fish remain poorly
collected and are often known from only a single specimen such as the
fathead sculpin Cottunculus
tubulosus (ResearchGate)
from the Mid-Atlantic Ridge. Endemic fish genera include the East
Pacific Ventbrotula (GBIF)
and an
anthias Anatolanthias (BHL).
A
spiny
lobster Palinurus
barbarae (Census
of Marine Life WM), a shrimp Alpheus waltervadi (GBIF),
a crab Chaceon collettei
(GBIF),
a starfish Iphiaster
noemieae (GBIF),
the gastropods Trivellona
inopinata (ResearchGate)
and Pterodacna boucheti
(PLAZI)
and Microcollonia
miniata (fig. 30 at ResearchGate),
an isopod crustacean Joeropsis
waltervadi (WoRMS),
and a sponge Biverticillus
tenuissimus (GBIF)
are known solely from the Walters
Shoals.
Other marine invertebrates collected only in International Waters include a copepod crustacean Stygiopontius lomonosovi (ResearchGate) from the Logachev Hydrothermal Vent of the Mid-Atlantic Ridge, the copepods Romete bulbiseta (G.L. Pesce WM pdf) and Meteorina magnifica (p. 2 of TOS pdf) and a black coral Leiopathes montana (ResearchGate) from the Great Meteor Seamount, a squat lobster Munidopsis mandelai (ResearchGate) and a bryozoan Atlantisina atlantis (Sciency Thoughts) from the Atlantis Seamount, a sponge Tedania rappi (Species New to Science) from the Orphan Seamount, a shrimp Leontocaris smarensis (p. 2 of TOS pdf) from the Romanche Fracture Zone, a shrimp Paralebbeus mollis (GBIF) and a sea cucumber Pannychia taylorae (ResearchGate) from the Coral Seamount, the gastropods Lirapex felix (ResearchGate) and Gigantopelta aegis (Wikipedia) and a polychaete Ophryotrocha jiaolongi (ZooKeys) from the Longqi vent field of the Southwest Indian Ridge, the gastropods Comitas powelli (Eddie Hardy) and Pleurotomella allisoni (Eddie Hardy) from the Agassiz Guyot, and a new species of red peniagone sea cucumber (p. 10 of Census of Marine Life WM pdf) from the Charlie-Gibbs Fracture Zone of the Mid-Atlantic Ridge.
Families
known solely from specimens collected in International Waters include a
copepod Parkiidae
(BHL),
an amphipod Microscinidae (GBIF) (PLAZI),
and the bryozoans Anyutidae (GBIF)
and Alyonushkidae (GBIF). Mollusc
families known only
from International Waters include the parasitic Galatheavalvidae
(p.
139 of Kobnhavens
Univ.
pdf)
collected east of Kenya on sea cucumbers and the Laginiopsidae (Marine
Species WM) from a single specimen collected east of the
Azores.
Areas in international waters likely to be important for endemic
species include seamounts (TOS
pdf), hadal trenches (ResearchGate),
hydrothermal vents (TOS
pdf),
and cold seeps (TOS
pdf). Some of the key areas are described at (Pew
pdf) and (IUCN
pdf). For a list of species endemic to the Meteors Seamount see
