scientist have lastly settle a 140 - year - old mystery story about how giant Antarctic sea spiders look after their eggs . Unlike other sea spider thatcarry their testis around until they incubate , the giant Antarctic sea wanderer ( Colossendeis megalonyx ) attach their thousands of flyspeck eggs to the rocky seafloor , a new subject area finds .
Sea spider are marine arthropods that live in oceans around the universe . They have eight extremely longsighted , thin stage that make them resemble , but are not related to terrestrialdaddy longlegsspiders ( folk Pholcidae ) .
Sea spiders are among the few marine arthropods whose males exclusively care for their offspring.
Many sea spiders only grow toup to an column inch long , but those that go at the perch , likeC. megalonyx , can have peg spans of up to20 in ( 51centimeters ) — a phenomenon know as " frigid gigantism " because they aremuch declamatory than sea wanderer in warm climates .

ocean spiders are among thefew marine arthropod whose males exclusively care for their offspring . " In most sea wanderer , the manful parent accept care of the babies by carry them around while they develop,“Amy Moran , guide generator of the new study and professor at the University of Hawai’i ’s School of Life Sciences at Manoa , said in astatement . While inquiry into the reproductive strategy of ocean wanderer go back 140 age , Moran say , the dwell conduct of three of the 11 recognized families of ocean spiders has never been observed , let in the phratry ofC. megalonyx(Collossendeidae ) .
Sea spiders are among the few marine arthropods whose males exclusively care for their offspring.
To determine how these ocean spider look after their eggs , loon entered the icy H2O of McMurdo Sound in Antarctica and hired hand - collectedC. megalonyxindividuals that appeared to be in match groups — name by individuals stack on top of each other . The pairs were then transported to the enquiry adeptness McMurdo Station , where they were maintain in tanks so their behavior could be observed , grant to the study , published on Feb. 11 in the journalEcology .

Two freestanding mating pair ended up laying 1000 of ball at the bottom of the tankful . However , rather than transmit the eggs around like other sea spider do , one parent , likely the male , spent two days tie the cloud - same brood to the floor of the tank car .
After a few week , the ballock appeared to be covered in alga , which made them hard to see within the tankful . In the wild , overgrown alga could aid camouflage these eggs against the seafloor .
" We were so favorable to be able to see this , " study co - authorMing Wei Aaron Toh , a doctoral scholar in the School of Life Sciences at the University of Hawai’i at Mānoa , said in the program line . " The chance to go directly with these amazing animals in Antarctica meant we could learn things no one had ever even guessed . "
