Despite their bright colors and ecological significance, many species of nudibranchs are significantly under-represented in scientific literature. One such understudied species is Polycera hummi, which inhabits the east coast of the United States in temperate to subtropical waters. While P. hummi has been previously recorded in Florida, little is known about the nudibranch’s population structure, feeding habits, and reproductive behavior. The goal of this study is to assess the seasonal distribution of Polycera hummi and gather ecological data on its diet, with a focus on its proposed prey the colonial bryozoan Bugula sp. Sampling is being conducted monthly in a seagrass bed in Tampa Bay to describe the population abundance of P. hummi and Bugula sp. Collected specimens of P. hummi are examined to record their size. Data will also be analyzed to examine the relationship between the sea slug and its prey. Preliminary data suggests a correlation between the abundance of Polycera hummi and Bugula sp. populations. For example, in May, 30 P. hummi individuals were collected, along with 848 individual colonies of Bugula sp. However, by September and November sampling, both P. hummi and Bugula sp. were absent from the collection site. This indicates a significant decline in the population of P. hummi from summer to fall, corresponding with the decrease in Bugula sp. abundance. A better understanding of the population dynamics and ecology of Polycera hummi will provide a baseline for this species’ life history and ecological role, paving the way for future research on this nudibranch.
