Brooding is a usual behaviour in animals. However, to
observe it in a marine worm is exceptional and, more surprisingly, it guards
eggs from external threats. The scientific finding, published recently in the
journal Polar Biology, was developed by researchers Conxita Àvila and Sergio
Taboada, from the Department of Animal Biology of the University of Barcelona
(UB) and members of the Institute of Research in Biodiversity (IRBio); Juan
Junoy, from the University of Alcalá; Javier Cristobo, from the Spanish
Institute of Oceanography, and Gonzalo Giribet and Sónia Andrade, from the
Harvard Univesity, among other experts.
