New research reveals wild octopus arms in action

Florida Atlantic University
Peer-Reviewed Publication

Think your multitasking is impressive? A new study reveals that wild octopuses use their arms with incredible complexity. Each of the eight limbs can perform any type of movement, but clear patterns emerged: front arms explore, back arms support movement. Even more impressively, individual arms can perform multiple actions at once – and coordinate across several limbs – showcasing the octopuses’ remarkable motor control in natural settings.

How many ways can an octopus flex its supple arms? Now we know

Marine Biological Laboratory
Peer-Reviewed Publication

The most detailed study ever of the complex motions of octopus arms as related to their behaviors will be published in Nature Scientific Reports this week by researchers from the Marine Biological Laboratory (MBL) and Florida Atlantic University (FAU). This study represents the first full ethogram, or detailed catalog, of octopus arm behaviors in the wild and builds on prior studies from the Roger Hanlon lab at MBL.

Death by a thousand cuts: salmon falling through the cracks in B.C.’s fragmented policy landscape

Simon Fraser University
Peer-Reviewed Publication

New research from Simon Fraser University (SFU) Biological Sciences researchers finds that Pacific salmon are facing escalating threats due to a lack of coordinated conservation policy and oversight.

Their study, published this week in FACETS outlines how the existing suite of environmental regulations across multiple jurisdictions in British Columbia is failing to manage the cumulative impacts of industrial development and climate change on salmon and watersheds, and suggests opportunities for reform.

Meat from critically endangered sharks is commonly sold under false labels in the US

Frontiers
Peer-Reviewed Publication

Researchers from the US determined the species of 29 samples of shark meat bought in shops or online. 93% had been labeled ambiguously as ‘shark’, and 31% overall were from four endangered or critically endangered species. Several of these species are known to contain dangerous levels of heavy metals. The authors call for better regulation of labeling and greater consumer awareness.
