Description:In marine mammal life history and health studies, knowledge of age is extremely important from both pathological and epidemiological perspectives, transcending population dynamic studies and allowing for a more complete assessment of an individual animal's overall biological health (Hohn 2018, Stolen and Barlow 2003). Ages of small odontocete cetaceans, such as common bottlenose dolphins, Tursiops truncatus, can be determined from either photo-identification records, from which an individual animal is tracked from birth by local research teams (e.g., Wells 2009), or estimated based on skeletochronology, examination of dentinal layers in teeth, from which each set of growth layers represents 1 yr of life (Hohn et al. 1989). Teeth can be collected for aging either at time of death or through extraction under local anesthesia during capture-release health assessments.
