Discovery without Destruction: a minimally invasive approach to new species

A new study by Ziegler and Sargony (2021) has demonstrated how non-invasive methods can be used to record and catalogue new species of megafauna. Traditional methods including collecting specimens to handle physically which, aside from killing the specimen, can also damage the structures of the organism - impairing proper scientific understanding. While non-destructive imaging techniques have proven effective in describing novel species of small organisms this is the first time it has be utilised for a deep-sea megafauna, the cirrate octopus - Grimpoteuthis imperator.

Some like it hot, but not salmon

Atlantic salmon (Salmo salar) are an important species of fish both for their ecological value and commercial value. These anadromous fish are spawned in rivers, travel to the sea to grow and mature before returning to the stream or river they were born in to spawn the next generation. As such the ability to swim against strong currents and up natural barriers is important, which is why a recent study published in the Canadian Journal of Zoology is concerning.

Hot sand poses further risks to endangered turtles

Leatherback turtles (Dermochelys coriacea) are the largest species of sea turtle. Found around the world's oceans they travel distances up to 4,828 km, using their large pectoral flippers to swim as fast as 24kph. Diving to as deep as 1000m these turtles follow the diel movements of jellyfish - their preferred prey.

Octopuses, neighbourly or not?

A recent study in the journal of Marine Biology has tested a different method of investigating social behaviour in octopuses. Traditionally octopuses have been seen as asocial creatures that ignore others of their species (conspecifics) but recent discoveries of aggregations or groups of wild octopuses such as: algae octopuses (Abdopus aculeatus), Graneledone octopuses, Muusoctopus octopuses, Caribbean Reef Octopuses (Octopus briareus), Atlantic pygmy octopuses (Octopus joubini), Octopus laqueus, Common Sydney octopuses (Octopus tetricus) and Vulcanoctopus hydrothermalis.

How Climate Change affects Baltic mussels

Mytilus mussels are keystone species in the Baltic Sea: they build reefs which provide more complex habitats for various species (macrofauna, macroalgae and meiofauna), filter water (linking the pelagic and benthic systems) and are a staple food source for numerous organisms (eider ducks, flounder, crabs, starfish and the larval stages feed herring larvae and other carnivorous zooplankton). They can also be extremely numerous – forming up to 90% of the animal biomass in some shallow waters.
