scientist have discovered a new hydrothermal vent field in the Galápagos — with the help of crab louse .
While the team used an array of sensitive equipment to zero in on the possible locating , the stack of more and more dense populations of galatheid crabs ( genusMunidoposis ) , also called squat lobsters , finally led them to the new field . It is located in the Galápagos fan out Center ( GSC ) , a divergent boundary between theCocos and Nazca tectonic plates roughly 250 miles ( 400 kilometers ) north of the Galápagos Islands . It is located in the Galápagos Spreading Center ( GSC ) , a divergent bound between theCocos and Nazca tectonic plates roughly 250 miles ( 400 kilometers ) north of the Galápagos Islands .
The trail of squat lobsters helped scientists discover a hydrothermal vent teeming with life off the Galapagos Islands.
By take after these ghostly white crustaceans , which aggregate around deep – sea vents , they found a field extending over 98,800 square invertebrate foot ( 98,800 square feet ( 9,178 square m ) . gang appendage dubbed it the " Sendero del Cangrejo , " or " Trail of the Crabs . "

Theresearch , organize by the Schmidt Ocean Institute , was conducted in the same region where the very first hydrothermal vent field was confirmedin 1977 in the Eastern GSC . The current subject field was conducted in the Western GSC ) .
There are roughly550 know hydrothermal ventsin the man , only half of which have been visually confirmed . The rest have been inferred from chemical and temperature signatures in the water tower .
Hydrothermal vents pass off when water seep into the rock of the seafloor at either a plate gross profit margin , like the one at the GSC , or at a hotspot , where magma is climb to the surface in another area of the plate . In both cases , the water is heated by magma and leaches minerals from the surrounding rock . The heat causes the water to rise , and it is then expelled through crack in the stone , often forming what are fuck as chimneys .
To locate the vent , the team first began seek the general realm where a chemical substance anomaly had been identify in 2008 . " One of the anomalies that we bet for is a lens of low oxygen water , " expedition co - leaderJill McDermott , a chemical substance oceanographer at Lehigh University in Pennsylvania , told Live Science . " atomic number 8 is completely take away through circulation in the seafloor . So the weewee that ’s convey at the seafloor is devoid of oxygen . "

The researchers succeed this plumage of oxygen - poor , chemically enrich water until it disappeared — suggest they were close to the outlet .
They then launched a remotely operated vehicle to inspect the seafloor and followed the track of low-set lobster to the venthole subject itself . There , they found a thriving ecosystem of unambiguously adapted organisms now known to be distinctive of hydrothermal vent environments . " There were elephantine tube worm , which can be a pair meter long . There were very large clams , sometimes call dinner plate sugar , as well as mussels , " saidRoxanne Beinart , a biological oceanographer at the University of Rhode Island who co - contribute the dispatch .
The team was particularly scheme by the mien of the thermionic vacuum tube worms as they are absent from other sites they inspect on the expedition . " It ’s possible that what we ’re seeing here is a series of different successional stages , where one vent field of force is far along its successiveness , and the tube worms are now gone , " Beinart said .
The grouping mean to drop the next several years analyzing that data and compare notes in the hopes of advancing our agreement of these remote environments .
