O expediţie condusă de “Census of Marine Life” s-a scufundat la 2700 m in zona Dorsalei Mijlocii a Atlanticului – lantul muntos submarin care strabate Atlanticul de la Nord la Sud, impartindu-l in doua - si a descoperit specii noi de animale. Biologii considera extrem de interesant un vierme primitiv (Enteropneusta) care desi lipsit de coloana vertebrala, prezinta caractere care ne-ar putea ajuta sa intelegem mai bine istoria aparitiei cordatelor.
