According tomedia BGR, you may not think that there is much in common with the creatures living on the deep seabed and other terrestrial animals. Most animals suffer from intense stress and lack of sunlight. Sponges are such creatures that they come in many shapes and sizes. But surprisingly, a special sponge called a glass sponge has something in common with humans and many terrestrial animals: sneezing.
Scientists at the Monterey Bay Aquarium Institute conducted an observational exercise to capture time-lapse footage of the California sea floor. Researchers studying the video found this particular line of sponges.
“Sneezing” is not particularly noticeable in itself, but it’s certainly noteworthy, and it’s strange for a sponge. As you can see in the video below, the sponge is made up of bone needles, with a white “cup” with a wine glass-like end at the end, and it expands and contracts. At first, scientists were puzzled by the strange behavior, but in the end came up with a possible explanation.
“There is a precedent for sponge contraction and expansion,” study co-author Amanda Kahn said in a statement. Basically, ‘ahh’ appears when the sponge expands, and ‘choo’ occurs when it shrinks. “
Deep-sea sponges filter food and other substances with rings and eventually become nutrients for their survival, meaning they hook up to any tiny particles floating as the water flows through them. However, not all of the things that are sandwiched by sponges are edible, and without a mechanism to eliminate harmful substances, sponges are much less efficient at obtaining the nutrients they need.
This “sneezing” behavior is thought to be a natural response of the sponge to harmful substances, draining irritating debris and then relaxing again to resume its normal eating behavior. Each sneeze can last up to an hour or up to several weeks. In time-lapse images, they look short, but these actions take some time to plug into tiny sponges.
