In this study, behavioral hearing tests were conducted with killer whales housed at SeaWorld San Diego (SWSD) that have not been tested previously, and complete audiograms were constructed. Additionally, updated audiograms were obtained for a group of previously studied whales (Branstetter et al., 2017) to obtain data on the effects of presbycusis

With harbor seals being an abundant marine mammal species in zoological institutions and their lifespan extending to greater lengths under professional care (Tidiere et. al., 2023), it is our job as animal care specialists to care for them as best as we can at all stages of life. This paper focuses on the training of a newconcept and correlating behaviors with Baby, a 0.1, 32-year-old harbor seal housed at Gulf World Marine Park.

The case of Pedro, a 25-year-old California sea lion diagnosed with cataracts, exemplifies the critical importance of preparation in marine mammal care. His story demonstrates how targeted training protocols can improve animal welfare by promoting voluntary participation in transportation and medical procedures.
