Abstract: Estimates of age and growth for bamboo coral (Keratoisis spp.) have been difficult to determine and only a few of these estimates had an actual temporal context. In this study, two bamboo coral colonies were collected from Davidson Seamount and analyzed for age and growth using lead-210 dating. The findings from both colonies converged on a radial growth rate of approximately 0.055 mm/yr. The calculated age of each colony was 89 years (range of 74-106 years) for a colony that stood 70 cm tall, and 145 years (upper limit of 450 years) for a large colony with irregular shape and height. Linear extension rates for each colony varied considerably with a range of 0.093 to 1.0 cm/year between the two colonies, which may indicate that linear growth rates are unreliable as an indicator of colony age.
