\n KENSINGTON, Maryland \u2014 Master builders of the sea construct the equivalent of a complex five-story house that protects them from predators and funnels and filters food for them \u2014 all from snot coming out of their heads.<\/p>\n

And when these delicate mucus homes get clogged, the tadpole-looking critters \u2014 called giant larvaceans \u2014 build a new one. Usually every day or so.<\/p>\n

These so-called \u201csnot palaces\u201d could possibly help human construction if scientists manage to crack the mucus architectural code, said Kakani Katija, a bioengineer at Monterey Bay Aquarium Research Institute.<\/p>\n

Her team took a step toward solving the mystery of the snot houses and maybe someday even replicating them, according to a study in Wednesday\u2019s journal Nature.<\/p>\n

The creatures inside these houses may be small \u2014 the biggest are around 4 inches \u2014 but they are smart and crucial to Earth\u2019s environment. Found globally, they are the closest relatives to humans without a backbone, Katija and other scientists said.<\/p>\n

Together with their houses \u201cthey are like an alien life form, made almost entirely out of water, yet crafted with complexity and purpose,\u201d said Dalhousie University marine biologist Boris Worm, who wasn\u2019t part of the study. \u201cThey remind me of a cross between a living veil and a high tech filter pump.\u201d<\/p>\n

Also, when they abandon their clogged homes about every day, the creatures collectively drop millions of tons of carbon to the seafloor, where it stays, preventing further global warming, Worm said. They also take microplastics out of the water column and dump it on the sea floor. And if that\u2019s not enough, the other waste in their abandoned houses is eaten by the ocean\u2019s bottom dwellers.<\/p>\n

But it\u2019s what they build that fascinates and mystifies scientists. Because the snot houses are so delicate, researchers haven\u2019t often been able to take them to the lab to study them. So Katija and team used a remote submarine, cameras and lasers to watch these creatures in water about 650 to 1300 feet deep off Monterey Bay in Northern California.<\/p>\n

These mucus structures aren\u2019t simple. They include two heart-like chambers that act as a maze for the food that drifts in, except there\u2019s only one way for it to go: into the larvacean\u2019s mouth. The snot houses often are nearly transparent and flow all around the critter that looks like a tadpole, but isn\u2019t.<\/p>\n

\u201cIt could be the most kind of complex structure that an animal makes,\u201d Katija said. \u201cIt\u2019s pretty astonishing that a single animal is able to do it.\u201d<\/p>\n

And the houses are comparatively big \u2014 about 10 times bigger than the critters themselves \u2014 reaching more than three feet wide (one meter). It would be the equivalent of a person making a five-story house, Katija said.<\/p>\n

\u201cThey create these small versions of houses by secreting mucus from cells on their heads and then expand those much like a balloon into the structures that we see,\u201d Katija said. All in about an hour.<\/p>\n

Water can flow through the structure so that when it moves through the water it doesn\u2019t give much of a motion detectable by predatory fish. That, Katija said, essentially masks the house from whatever wants to eat the larvaceans.<\/p>\n

NASA engineers looking to build structures on the moon would probably like to learn from the larvaceans, she said.<\/p>\n

None of this could be done in the lab. Katija\u2019s team used 3D laser scan technology<\/a> to virtually fly through the inner chambers of the snot palaces, then recreated them with software to model the inner-workings of the structure. But she said the scientists are still far from understanding everything going on there.<\/p>\n

Providence College biologist Jack Costello, who wasn\u2019t part of the study, said Katija\u2019s team did \u201creally cool work \u2026 to detail the complex houses. It\u2019s not easy to do in the best circumstances and they\u2019ve done it deep in the oceans.\u201d<\/p>\n

\u201cWe have a lot to learn,\u201d Costello said. \u201cI\u2019m in awe of these animals.\u201d\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/div>\n
