This was my first peer-reviewed publication and the third chapter of my PhD thesis. It primarily looked at the age and growth of the milk shark, Rhizoprionodon acutus. Assessment of age was difficult because this species has an aseasonal reproductive strategy, with young apparently born throughout the year. When attempting to determine age from counting growth rings, this leads to considerable uncertainty in the age that the first growth ring is formed, which can be quite important given the species completes much of its growth within the first year of life.
