The scientists looked at how one group of wood-boring clams has evolved to build chimneys of their own poop. These clams, about the size of a pea, develop the poopy structures as a method to ensure they get more of this marine wood for themselves. They dig into the wood, forming a borehole that then becomes both a source of food and a safe shelter.
While some of the wood on the seafloor can be packed with a large range of animals, others pieces that researchers found were so gnawed on and chewed up that they crumbled when dealt with. The researchers wanted to determine why this takes place. After looking at the species of wood-boring claims present in wood samples from all over the world, they started observing a pattern.

When you consider animals digging in wood, clams are most likely not the ones that appear. Some clam species actually grow on sunken pieces of wood at the bottom of the sea, according to a brand-new research study. The wood, either from fallen trees or from ships, is teeming with life and can provide a home and nutrients to live on. But the actually gross part follows after that.
” There are two difficulties every sea creature needs to deal with: getting distilled water in, so you can get oxygen to your gills, and getting rid of your waste. Since nobody wants to live in their poop. However here are these clams dealing with theirs, and really thriving,” Janet Voight, the research studys lead author and Field Museum manager, stated in a statement.
A very uncommon set of clams
Aside from resolving the mystery of the chewed-up wood, Voight said the research study shows the significance of taking a look at ecology with an understanding of how different types are linked to each other, and why just this species acts like this. When youre confronted with something that appears enigmatic, in some cases you require to go back and look at the huge image, she concludes.
The research study was released in the journal Marine Biodiversity.
As the shell digs in, the siphons (tubular body parts that take water to get oxygen and eject waste), stand out behind it. While the majority of wood-boring clams have long siphons that protrude into the water, these clams have a much shorter siphon thats utilized to expel the de-oxygenated water and the feces in fact stay inside the borehole.
There are 6 branches in the wood-boring claim family 3, however only one species was really accountable for breaking the wood. “You simply presume all wood-boring clam species bore into the wood the exact same method,” Voight stated, who discovered the clams in the clade Xylophaga dorsalis was accountable for all the pooping and chewing. They dont.
Previous research studies recommended that the chewed-up wood was since of warmer water or more larvae close by. Now, this brand-new research study is recommending the clams are the real offenders. As they dig and move into the wood, they fill the area around them with their own feces. And they do not do it on purpose, its simply physiological, Voight stated.
The waste inside the clam forms a sort of fecal chimney that wraps around the siphon. Its probably not the most hygienic way to live, but it doesnt appear to conserve the clams from a great deal of trouble they might run into otherwise. In fact, the poop chimney might in fact act as a signal for clam larvae to settle in the wood, the researchers assumed.
