💨 Abstract

Jellyfish populations have surged along the Delaware coast this summer, leading to a significant increase in stings. Lions' manes and sea nettles, among other varieties, have been prevalent. Warmer waters are contributing to these blooms. Delaware's various beaches have seen a dramatic rise in jellyfish stings, with some reporting over 1,200 cases in 2025 compared to 295 in 2024.
