A series of experiments with this genus showed no changes in reproductive rate and an age-specific mortality rate of zero for several cohorts, suggesting that these organisms do not undergo senescence.
Organisms in this genus code for a receptor protein-tyrosine kinase whose extracellular lectin-like domains are called Sweet Tooth. One species of this genus may appear green because they host the alga Chlorella. Davis and Bode wrote early monographs on maceration techniques used to isolate individual cells of this organism. A series of experiments with this genus showed no changes in reproductive rate and an age-specific mortality rate of zero for several cohorts, suggesting that these organisms do not undergo senescence. David Martinez conducted his immortality experiments with these organisms, which include species named vulgaris and viridis. They have organizing centers at their basal disc and the hypostome. These cnidarians are known for their ability to undergo morphallaxis, in which they regenerate tissue that is severed. For 10 points, identify this genus whose members are able to regenerate tissue like its mythical namesake.
