Dive into marine natural history with the Oceanic Whale Mammal Tee, featuring a hand-drawn illustration of Megaptera novaeangliae—the humpback whale. Known for their acrobatic breaches and complex vocalizations, these baleen whales traverse thousands of kilometers across ocean basins, playing a key role in marine ecosystems. This scientific-style design pays tribute to cetacean biology and the rich biodiversity of the pelagic zone. Every order funds kelp restoration on the Pacific Northwest coast.
