Coffinfish – How Long a Coffinfish Can hold its Breath?

(Last Updated On: April 13, 2021)

With names like coffin fish, it is no surprise that these wonderful-looking creatures evolve under the dark sea with their mysterious biological traits and facts. This interesting Coffinfish, which scientific name is Chunnax endeavor, is a deep-sea fish breed under Chonasidae family.

It is found in the salty tropical waters of the southwestern Pacific Ocean off the east coast of Australia. It can also be found at depths of 164-984.3 feet (50.0–300.0 meters).

Deep-sea crab fishermen on the east coast of Florida are dragged from their depths about 3-5 miles away. They have a globose and polarized body with a maximum length of 22.0 cm (8.7 inches) (SL male / unsexed) and a black face lining and an ellipse that can be lowered down a notch.

Coffin fish can hold its breath for four minutes

No wonder this fish looks like an indifferent, inflamed balloon – it has been churning over a lot of water for ages.

This strange little creature is known as the Coffinfish (Chunnax Endeavor) and lives in the deepest part of the Pacific Ocean.

For the first time, this “breathing” behavior has been revealed by publicly available videos maintained by the National Oceanic and Atmospheric Administration (NOAA), Science said.

Scientists already knew that deep-sea dwellers, sometimes called sea tudacs – have special fins for “walking” along the shore.

But now, a new study has revealed another coffinfish adaptation – the huge, inflatable gill chamber that extends the body of animals with sea water, receiving more oxygen and holding their breath for four minutes.

This behavior – discovered for the first time in a fish – can be a way to store energy in a food-scarce environment. (Read how the fish jumped from the water to the ground))

“It’s great – it’s like a separate inflation method that no other fish uses,” said Stacey Farina, co-author of the study, an assistant biology professor at Howard University.

For example, pufferfishes withhold a large amount of marine water to propagate their highly elastic stomachs.

This national deep-sea adaptation study helps biologists improve their knowledge of the various ways that they have evolved to live in extreme environments.

There are more than 20 species of coffinfish, in fact, a type of anglerfish found at depths up to 8,200 feet.

“They have completely adapted to being a marine animal. They rarely swim, ”added co-author Nick Long, who pursued the study as a graduate biology student at Dickinson College, Pennsylvania.

“Some people call them lazy.”

For research, Farina and Long isolated and CT-scanned coffin fish specimens at Harvard University’s Comparative Zoological Museum, where Farina was a postdoctoral fellow at a number of non-native species of video captured by drones operated by the Okinos Explorer ship of the National Oceanic and Atmospheric Administration. Did.

According to a recently published study in the Journal of Fish Biology, sea toads contain inflatable gill chambers that can increase their body mass by up to 30 percent. In terms of a person, this means your lungs are swelling to the full stomach, says Farina.

The team was particularly interested in the fish’s unique ability to hold its breath, which the video suggested as part of its normal breathing. Such behavior is commonly seen in pulmonary animals, although catfish hold their breath in oxygen situations for a short time, he said.

Scientists suspect that coffinfish inflame their bodies in conserving energy – breathing, after all, requires some effort.

Although coffinfish will eat anything that is in their mouths – from fish to octopus to worms – “Lund said that the chances of the victim’s presence on a particular day are very low.”

John Caruso, a senior professor at Tulane University who was not involved in the study, called it “great.”

Fish get water (which is two parts hydrogen and one part oxygen) to obtain the oxygen they need to survive, collect oxygen and then “release their breath” by releasing oxygen-drained water from their gills, according to science. But these fish hold water over their large swallow chamber instead of leaving it immediately for 2 to 2 minutes for 4 minutes.

Scientists also carried out a mathematical tomography (CT) scan of the coffinfish’s collection specimens to test how many gill chambers the animals hold for water.

Why fish do this, researchers have some estimates. They say that holding breath can help preserve fish’s strength. It can even protect them by showing them even bigger ones, such as what the Pfarfish can achieve by pushing their stomachs
