In the Norwegian coasts, fjord sills don’t seem to act as physical barriers limiting gen flow, as has been reported for other mesopelagic fish species.

Our analyses revealed habitat-driven differentiation in 3 main units: Mediterranean Sea, oceanic samples and Norwegian fjords. In the Mediterranean Sea, the complex topography of the Greek seas is probably shaping the genetic structure.

The silvery lightfish is one of the most abundant species inhabiting the North Atlantic mesopelagic layer. Despite its ecological importance there is insufficient knowledge about its population genetic structure.
I am in Glasgow at #OSM26. Join me in the Poster Session on Wednesday (16:00-18:00) to know more about the selectivity of lanterfishes towards bioluminescent prey.

Their ability to tolerate low oxygen levels and the regular length of day and night in the study area are also key aspects.

In the Arabian Sea, the biomass of lanternfishes is particularly high, but dominated by only a few species.
Much of the high production of the Arabian Sea is channelled via zooplankton to the stock of lanternfishes due to the low abundance of competing small pelagic fish.

Why are so many lanternfishes in the Arabian Sea?
Lanternfishes (Family Myctophidae) are one of the most common and abundant families among the fishes living in the twilight zone and play a key ecological role in the pelagic ecosystems.
Here's my take on a vampire squid dressed up as Bela Lugosi's version of Dracula.
Here’s the twist: it doesn’t drink blood.
It lives in the dark, deep sea.
But Instead of hunting the living, it drifts silently through the deep, collecting “marine snow”, tiny flakes of dead plankton and detritus sinking from the surface.
I am all in a sea of wonders.
Dracula, Bram Stoker
The vampire squid Vampyroteuthis infernalis, it's name literally means “the vampire squid from hell.”
Sounds like a Halloween nightmare, right?
So behind the Dracula cape hides not a monster, but a gentle recycler keeping the deep sea clean.
