Pinpointing the longest-dwelling organisms also depends on defining what constitutes an "individual" organism, that may be problematic, considering the fact that many asexual organisms and clonal colonies defy one or both of the normal colloquial definitions of individuality (acquiring a definite genotype and obtaining an impartial, physically separate body).

, a cold-seep species of tube worm within the Gulf of Mexico, routinely lives as many as two hundred years, and some specimens survive for greater than 300 a long time.
