Take into account the clam.
Think about that its two iconic shells have shrunk right into a collar, fringed with jagged tooth, which it makes use of to gnaw via wooden. Think about that its digestive tract and a lot of the remainder of its organs have gotten pushed out the backdoor of the shell, forming a protracted streamer of flesh that it retains protected by burrowing into the wooden it eats. And picture that it’s larded with symbiotic micro organism that support the creature within the digestion of all that wooden.
Congratulations: You’ve arrived on the shipworm.
Shipworms and their weird wood-eating life-style loomed massive within the fears of sailors for hundreds of years, as they’ll ship a vessel to the underside with little greater than concerted munching. Even right now they’ll deliver buildings with wooden pilings beneath them, like Pier 5 in Brooklyn, to their knees. However they’re additionally intriguing as potential sources for brand spanking new antibiotics, amongst different issues, which led a staff of researchers final 12 months to a river mouth within the Philippines the place they pulled up a chunk of wooden that turned out to comprise a brand new species of shipworm, which they named Tamilokus mabinia.

The invention, which was reported within the journal PeerJ on Thursday, occurred throughout a feverish episode of wading via mangroves and scuba diving in coastal waters searching for wooden that contained shipworm burrows. The staff introduced their finds to the parking zone of a beachgoers’ lodge, the place, carrying headlamps and wielding axes, they extracted the worms and introduced them as much as their hotel-rooms-cum-biology labs.
“It’s not what you anticipate while you guide your seashore holidays to see folks doing this,” mentioned Reuben Shipway of Northeastern College, one of many research’s co-authors. However working shortly allowed the staff, generally known as the Philippine Mollusk Symbiont Worldwide Collaborative Biodiversity Group, to determine, and start the method of sequencing the DNA of the animals and their bacterial symbionts instantly.
When Dr. Shipway extracted one of many tiny captured shipworms from its burrow, he knew instantly he was one thing new.
“That is most likely a brand new species, instantly simply from wanting on the siphons,” he mentioned he recalled considering, as he examined the tubular buildings that enable the worms to expel waste. “They had been pink and pinstriped.”
Again on the opposite facet of the world in a lab in Boston, the researchers confirmed that the pink-striped shipworm, which may vary in dimension from about 2.5 to six inches lengthy, was not solely a brand new species however a consultant of a brand new genus. They explored its insides utilizing a kind of CT scanning and realized that its organs are organized in a sample uncommon even for a shipworm. Not solely have its coronary heart and kidneys swapped locations, however one portion of the digestive system is extraordinarily lengthy.
“It’s about six occasions as lengthy” as that of most different shipworms, maybe to assist in the processing of its meals, mentioned Dan Distel, additionally of Northeastern.
The researchers now plan to sequence the genomes of the micro organism that stay inside the new shipworm to study what they’re and what sorts of gear they make.
“Some shipworms have as many as ten totally different symbiont species,” Dr. Distel mentioned.
Finding out these micro organism might assist reveal particulars of how this species lives, in addition to present new leads for substances which might be helpful to folks, like digestive enzymes that would assist make biofuels. It’s all part of these creatures’ transition in some people’ eyes from harmful pest to fascinating obsession.
