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.

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.

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.

Dolphin population uses different whistles to beat noise

A recently recorded population of Indo-Pacific Humpback dolphins has been observed using their own distinct whistles which have longer durations, lower frequencies and fewer inflection points. Not only does this suggest they are an independent population but researchers suggest that the specific features of this delphinid language are used to communicate more effectively in the waters around Hainan Island, Zhanjiang, and Sanniang Bay.

Canadian Sealers barred from clubbing – “NO SHIRT, NO SHOES, NO ENTRY” say polar bear bouncers

The Canadian seal hunting season came to an abrupt end when fishermen were faced with a firm refusal of entry by stern polar bears. “I couldn’t believe my ears!” Canadian fisherman, Linden told us. “I was getting ready to jump on the ice with my trusty hakapik when a polar bear held up his hand to stop me.”

New estimates of marine plastic pollution from COVID-19 face masks

Following in the wake of the Covid-19 pandemic were growing fears and numerous accounts of discarded single use PPE making its way into the world’s oceans. Yet despite these very real concerns there is no extensive quantitative estimation of the amount of discarded face masks likely to litter coastal regions.
