Do Some Electric Fish Sense the World Through Comrades' Auras?

NEW YORK, March 6, 2024 /PRNewswire/ -- It would be a game-changer if all members of a basketball team could see out of each other's eyes in addition to their own. A research duo at Columbia's Zuckerman Institute has found evidence that this kind of collective sensing occurs in close-knit groups of African weakly electric fish, also known as elephantnose fish. This instantaneous sharing of sensory intelligence could help the fish locate food, friends and foes.

Key Points:

We showed that something similar may be happening in groups of fish that sense their environment using electrical pulses.
Scientists have long known that electric fish sense changes in the electric fields they project into their waterscapes, much like the acoustic signals that bats and dolphins deploy.
The fish rely on specialized organs in their skin that emit and sense electric fields to communicate.
They analyzed whether individual electric fish were better at detecting objects by tapping into signals emitted by nearby fish.

We’ve found out how earless moths use sound to defend themselves against bats – and it could give engineers new ideas

Bats count on their secret weapon, echolocation, to find and catch their flying prey, and in response, nocturnal insects have evolved interesting defences.

Key Points:

Bats count on their secret weapon, echolocation, to find and catch their flying prey, and in response, nocturnal insects have evolved interesting defences.
Many silk moths, for instance, rely on a kind of sound-absorbing stealth cloak that makes them “disappear” from bat sonar.
However, scientists have long been puzzled about the many earless moths that cannot detect their predators and are too small for decoys.
We recently discovered that even earless moths, such as ermine moths (Yponomeuta), use acoustic signals as a defence against bat attacks.

Protective wing beats

When we studied the ermine moth’s wing under a microscope, it became clear that one part of the wing stands out from the rest. While most of it is covered by small hairs and scales, one patch of wing is clear and located adjacent to a corrugated structure of ridges and valleys. In our new study, we found this structure produces sound perfectly tuned to confuse bats.

As the drum skin is struck by a drumstick, the skin vibrates at its natural frequencies and transmits these vibrations into the surrounding air as sound.
In ermine moths, the clear patch in the hind wing serves as the drum skin, while the corrugated structure of valleys and ridges act as drumsticks.
During flight, the moth’s wing makes the ridges snap one after the other in a sequence.
To our team of biologists and engineers, these wing structures are fascinating because they rely on a mechanism that we teach our engineering students to avoid.

Inspired by nature

One example is engineers designing morphing structures for future aircraft wings that autonomously adapt their shape to perform better when the environment changes.
The aeroelastic tymbal of ermine moths embodies this concept and demonstrates how nature can be an inspiration for new technology.

"WWF-Canada is calling for not only the release of the delayed Ocean Noise Strategy, but for one strong enough to deliver meaningful, measurable and urgent action that whales and other species impacted by underwater noise pollution desperately need."

Key Points:

"WWF-Canada is calling for not only the release of the delayed Ocean Noise Strategy, but for one strong enough to deliver meaningful, measurable and urgent action that whales and other species impacted by underwater noise pollution desperately need."
To hit the right note, Canada's Ocean Noise Strategy should:
Establish noise limits for activities we know have a negative effect on soundscapes, such as shipping and oil and gas exploration.
Put in place regulations for ongoing monitoring of noise levels and enforcement of noise limits and reduction targets.
Without teeth, it's unlikely Canada's Ocean Noise Strategy will help mitigate noise pollution.

Why can't we just tow stranded whales and dolphins back out to sea?

On Tuesday night, a pod of almost 100 long-finned pilot whales stranded itself on a beach on Western Australia’s south coast.

Key Points:

On Tuesday night, a pod of almost 100 long-finned pilot whales stranded itself on a beach on Western Australia’s south coast.
They used small boats and surf skis to try to get the pilot whales into deeper water.
It can work and work well, as we saw in Tasmania last year, when dozens of pilot whales were rescued.

Rescuing beached whales is hard

When we try to rescue stranded whales and dolphins, the goal is to get them off the sandbars or beach, and back into deep water.
First, you have to know that a pod has beached itself.
Then, you have to be able to get there in time, with people skilled in wildlife rescue.
And to add to the problem, pilot whales are highly social.
Because of these reasons – and probably others – it wasn’t possible to save the pilot whales yesterday.

Successful rescues do happen

Every single person working around the clock to help these animals did an amazing job, from experts to volunteers in the cold water to those making cups of tea.
Last year, 230 pilot whales beached themselves at Macquarie Harbour, on Tasmania’s west coast.
Surviving pilot whales were helped into a sling, and then the boat took them far out to sea.

Every stranding lets us learn more

Are they avoiding predators such as killer whales?
We do know there are stranding hotspots.
In 2020, it was the site of one of the worst-ever strandings, with up to 470 pilot whales stranded.
Whales and dolphins with teeth – such as pilot whales – appear to beach a lot more.
