Clavelina picta is a tunicate in the subphylum Tunicata, a sister subphylum to the Vertebrata. Humans are members of the subphylum Vertebrata. These simple-looking organisms are marine filter-feeders with a sac-like body structure. These "higher animals" are the first we've seen in the numerous trips we've made to St. John.
