(Laughter) So here we are, after 20 years of essentially studying these animals, genome mapping, chin scratching, and thousands of amputations and thousands of regenerations, we still don't fully understand how these animals do what they do.
(Riures) Així que, aquí estem després de 20 anys estudiant aquests animals, de mapejar el genoma,  de rascar-nos la barbeta i de milers d'amputacions i de milers de regeneracions i encara no entenem com  aquests animals fan el que fan.
