Listen to the carol created by the experts from the University of Exeter with the sound of clownfish and other marine species that live in the Sea Life aquarium in London

A team of marine biologists from the University of Exeter (England) and engineers have composed an aquatic version of the famous Christmas song Jingle Bells with the sound made by clownfish (Amphiprion ocellaris) and other marine species, such as crab or horse of sea, at the London’s aquarium ‘Sea Life’. The mix has been done in the famous Abbey Road Studios.

To record previous recordings of marine animals, experts used equipment capable of detecting sound waves underwater. They used hydrophones (sound to electricity transducers that can be used in water) to listen to the 300 clownfish in the aquarium.

The experts gathered croaking noises, bursts and purrs when individuals tried to show their dominance over others. They also recorded an ‘argument’ among crabs in which opponents apparently competed for food.

Finally, one of the two made a ‘trumpet’ sound, signalling his surrender. In addition, they also compiled the clicks made by seahorses by swallowing the food noisily, as well as a continuous growl of a Lagoon triggerfish (Rhinecanthus aculeatus).

Fish do have a ‘voice’

Although most people think that fish do not have the ability to make sounds to communicate with, Steve Simpson, a professor at Exeter University and research leader, says that sound is crucial for many aquatic species. “There are many reasons why fish make noise, including defence of territories, warning against predators and during courtship,” he explains.

“Sound plays an important role in the health of our oceans and we are curious to know how the different species of fish use language to communicate with each other or, at least, find in time a fish that had a vocal range like Mariah Carey to Christmas,” said James Wright, curator of exhibitions at the SEA LIFE aquarium in London.

The importance of sound in the reefs

Over the past decade, Simpson and his colleagues have provided the first clear demonstration that the settlement stage of numerous coral reef fish species is attracted to the sounds of the reefs and that they establish a connection with these sounds in one phase. Very early development.

Clownfish embryos, for example, respond to noise from three days of life. When they are born, most species spend days to weeks growing in the open ocean. When the time comes to settle on a reef, they are attracted to the sounds they experienced as an embryo, since it was a place where their parents were able to live and reproduce successfully.

Further research by Simpson and his colleagues found that adult reef fish are also directed towards the noise of the reef, selecting the frequencies that are produced by other animals.
