Lumbar Specialization And The Evolution Of Swimming Modes In Cetaceans, Caedmon Morgret, Ryan Bebej
Summer Research
Locomotion describes how an animal moves through its environment. The driving force behind locomotion in cetaceans (whales, dolphins, and porpoises) is the vertebral column and its associated muscles, tendons, and ligaments. Lumbar vertebrae represent one of several vertebral regions in the column (Fig. 1) that dictate cetacean swimming mode1 . Ancient cetaceans had four limbs and were able to move around on land, with swimming capabilities similar to modern terrestrial/semiaquatic mammals2 . Over time, as cetaceans became more aquatic, they transitioned from using limb-dominated swimming to taildominated swimming, which required drastic functional changes in the lumbar region. Prior work demonstrates …

The desire of animal behaviorists for more flexible methods of conducting inter-study and inter-specific comparisons and meta-analysis of various animal behaviors compelled us to design an automated, animal behavior peak detection method that is potentially generalizable to a wide variety of data types, animals, and behaviors. We detected the times of feeding attempts by 12 Risso's dolphins (Grampus griseus) and 36 blue whales (Balaenoptera musculus) using the norm-jerk (rate of change of acceleration) time series. The automated peak detection algorithm identified median true-positive rates of 0.881 for blue whale lunges and 0.410 for Risso's dolphin prey capture attempts, with median …
