Dear colleagues, As part of my Master's research, I aim to adjust a method to estimate the total body length of humpback whales (Megaptera novaeangliae) through the photogrammetry technique using the fluke width measurements to correlate with total body length, as proposed by Sousa-Lima & Groch (2010). These two measurements have a linear correlation as it was demonstrated in previous studies. To calibrate even more this correlation, we are going to develop allometric equations for body length of humpback whales. I would be thankful if any Marine Mammal Stranding organizations who have collected or will collect the measurements of this species, and the gender of the animal, to get in contact if is willing to share the data. My aim is to create an effective method to estimate total body length of living whales jointly using the allometric equations and the photogrammetry technique. Measurements of body size of free range humpback whales aid significantly in the understanding of important aspects of their biology and behavior, primarily in a breeding ground since the body size is often correlated with mating success.
