Drunk Fish Swim Faster… And The Sober Fish Try To Keep Up

Published

on

When a single fish gets tipsy, it swims faster than usual. This was already known.  But what happens when it is thrown into a tank with sober fish? The fish swims even faster than when it is alone, and, furthermore, the whole school speeds up. The sober fish may take the soused swimmer’s speed and uninhibited fin-flapping for leadership.

“These results were very surprising,” said NYU researcher Maurizio Porfiri, who led the study, in a statement. “It is clear that the sober fish were matching the swimming speed of the alcohol-exposed fish, and this correlation was especially strong at an intermediate level of alcohol exposure. At very high or low levels, the influence decreases.” Especially at high concentrations, the very drunk fish are sluggish, and have trouble keeping up with the rest of the school.

What does it all mean? It shows the effects of alcohol are different in a solitary verses a social setting in zebrafish, and that boozy behavior of a single individual can affect the whole group – of interest to researchers studying alcoholism and sociality. It also shows how disinhibited, aggressive behavior can in this species resemble leadership. Are you my leader, or are you just drunk as a fish? It’s thought that the individual swims faster around its shoalmates in part because it has increased interest in interacting with them – kind of the way the bottle can bring out a shy human.

In related drunk-fish science news, a study (also by Porfiri) found that normally zebrafish are afraid of a robotic fish that looks like one of their predators. But not when they’re drunk – then do not appear to be afraid of the artificial threats.

the ocean cleanup

6 years ago, The Ocean Cleanup set sail for the Great Pacific Garbage Patch with one goal: to develop the technology to be able to relegate the patch to the history books. On 6 September 2024, The Ocean Cleanup fleet returns to San Francisco bringing with it System 03 to announce the next phase of the cleanup of the Great Pacific Garbage Patch and to offer you a chance to view our cleanup system up-close and personal.
We look forward to seeing you there.

To confirm your presence, please RSVP to press@theoceancleanup.com

PROGRAM

Join The Ocean Cleanup as our two iconic ships and the extraction System 03 return to San Francisco, 6 years and over 100 extractions after we set sail, to create and validate the technology needed to rid the oceans of plastic.
Our founder and CEO, Boyan Slat, will announce the next steps for the cleanup of the Great Pacific Garbage Patch. Giving you a chance to view our cleanup system and the plastic extracted.
Hear important news on what’s next in the mission of The Ocean Cleanup as it seeks to make its mission of ridding the world’s oceans of plastic an achievable and realistic goal.
Interviews and vessel tours are available on request.

ABOUT THE OCEAN CLEANUP
The Ocean Cleanup is an international non-profit that develops and scales technologies to rid the world’s oceans of plastic. They aim to achieve this goal through a dual strategy: intercepting in rivers to stop the flow and cleaning up what has already accumulated in the ocean. For the latter, The Ocean Cleanup develops and deploys large-scale systems to efficiently concentrate the plastic for periodic removal. This plastic is tracked and traced to certify claims of origin when recycling it into new products. To curb the tide via rivers, The Ocean Cleanup has developed Interceptor™ Solutions to halt and extract riverine plastic before it reaches the ocean. As of June 2024, the non-profit has collected over 12 million kilograms (26.4 million pounds) of plastic from aquatic ecosystems around the world. Founded in 2013 by Boyan Slat, The Ocean Cleanup now employs a broadly multi-disciplined team of approximately 140. The foundation is headquartered in Rotterdam, the Netherlands, and opened its first regional office in Kuala Lumpur, Malaysia, in 2023.

SHARK MONTH ARRIVES AT ROYAL WILLIAM YARD, PLYMOUTH

Published

on

A shark has been spotted approaching Royal William Yard in Plymouth, much to the surprise of swimmers, paddleboarders and onlookers.

With its distinctive dorsal fin cutting through the water, the sizeable shark swam along the coastline, before turning to head inland towards Firestone Arch at Royal William Yard. The appearance drew a crowd, who were captivated for more than an hour by the unusual sight – and it was all caught on video.

The shark is one of many expected sightings at Royal William Yard over the coming weeks… because today marks the start of Shark Month!

In reality, the ‘shark’ spotted along the Plymouth shoreline was actually a custom-made model, created by the team at Royal William Yard and sailed underwater by Caroline Robertson‑Brown​​​​ from the Shark Trust, who donned scuba diving gear for the occasion.

The stunt took place to launch Shark Month in style and draw attention to the work of the leading international conservation charity, which is based in Britain’s Ocean City. Spectators were reassured that the water was safe and many entered into the spirit of the performance, swimming or sailing alongside the shark.

Shark Month will take place across Royal William Yard throughout July and will feature an extravaganza of art, entertainment and advocacy for everyone to enjoy. The packed programme of events starts with an art exhibition and ends with a trip on paddleboards with shark experts – with everything from a shark quiz to a Jaws screening in between.

Paul Cox, CEO of the Shark Trust, said: “There are often assumptions and misconceptions when it comes to sharks. This was certainly the case with the shark spotted at Royal William Yard! While the British coastline is home to many species of shark, this was not one of them. However, we’re thrilled it caught people’s attention, because seeing a shark is a special and memorable moment. That is precisely why we want to celebrate these incredible creatures, highlight the need for conservation, and ask for help to safeguard their future.”
