A Pacific grenadier Coryphaenoides acrolepis in the south-west Atlantic and environmental changes in the Falkland deep seas

  • Vladimir Laptikhovsky (a1), Michelle R. Gaither (a2) and Alex Black (a1)

One individual of the Pacific grenadier, Coryphaenoides acrolepis, was recorded for the first time in the South Atlantic (54°00′S 56°52′W–53°57′S 56°44′W, depth range 1540–1860 m). The species is endemic to the North Pacific, and its appearance off the Falkland Islands, as with some other endemic North Pacific species found there recently, might be possibly explained by changes in water circulation in deep seas. During the last decade deep waters around the islands have become less saline and warmer, which is in agreement with respective changes in water masses in Antarctica.
