Journal of Fish Biology, EarlyView.Abstract Chondrichthyans (sharks, rays and chimaeras) are increasingly understood to be an important part of ocean ecosystems, but their ecological role is unclear. Callorhinchus milii (elephant fish) is a chimaera species endemic to Aotearoa/New Zealand and southern Australian waters.

Understanding marine biodiversity patterns and drivers: The fall of Icarus
Marine Ecology, EarlyView.Abstract Biodiversity patterns are fundamental in our understanding of the distribution of life, ecosystem function, and conservation. In this concept analysis, A survey of the existing knowledge on marine biodiversity patterns and drivers across latitudes, longitudes, and depths indicates that none of the postulated patterns represent a rule.

Diet of Risso's dolphin (Grampus griseus) in the western Mediterranean Sea
Scientia Marina, 2006 The diet of Risso’s dolphin in the Mediterranean is described based on 15 animals stranded between 40°25’N 00°32’W and 37°35’N 00°45’E from April 1987 to January 2003. The prey were mainly oceanic cephalopods. Pelagic octopods, especially A.

The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?
Marine Ecology, EarlyView.ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...

mTOR as a Marker of Exercise and Fatigue in Octopus vulgaris Arm
Frontiers in Physiology, 2019 Cephalopods are highly evolved marine invertebrates that colonized almost all the oceans of the world at all depths. This imposed the occurrence of several modifications of their brain and body whose muscle component represents the major constituent ...

A Spontaneous Mutation in tfoX Impairs Bioluminescence in Photobacterium kishitanii ANT‐2200
Molecular Microbiology, EarlyView.A frameshift mutation in tfoX generates a truncated regulator associated with reduced lux–rib expression and low luminescence. Complementation with wild‐type tfoX restores transcription and light production, supporting a role for TfoX in regulating bioluminescence independently of quorum sensing.

Renewed Perspectives on the Deep Roots and Broad Distribution of Animal Consciousness
Frontiers in Systems Neuroscience, 2020 The vast majority of neurobiologists have long abandoned the Cartesian view of non-human animals as unconscious automatons—acknowledging instead the high likelihood that mammals and birds have mental experiences akin to subjective consciousness.
