If you thought dolphins were only known for their playful swims and acrobatics, think again. These male dolphins have adopted an unexpected “fashion statement” — and it’s all in the name of love.
So, is this behavior truly a sign of courtship, or just another quirky game of nature? Let’s dive into what researchers have discovered.
Male humpback dolphins have been observed wearing sea sponges on their heads — yes, like wigs! According to researchers, this unique act seems to be a sexual display designed to attract females. The behavior was first recorded by a research team from the Department of Biodiversity, Conservation and Attractions (DBCA), led by Dr. Holly Raudino. The team noticed male dolphins placing sea sponges over their rostrums (the front part of their snouts).
DBCA even shared on Instagram, jokingly:
“These dolphins might look like barristers heading to court, but they’re not preparing legal arguments — their sponge wigs are just to impress the ladies!”
Dr. Raudino explained to ABC News that these sea sponges come in various shapes and colors, but are all found in a specific region along the coast. Interestingly, this behavior has not been observed anywhere else in the world, even in other populations of humpback dolphins. It appears to be a uniquely Australian phenomenon, concentrated around the Pilbara, Kimberley, Edith Smith Gulf, and Dampier areas.
Meanwhile, Liam Ridgley, a marine tour operator at Shark Bay, shared that local bottlenose dolphins also use sea sponges — but for a completely different purpose. Female dolphins there use them as tools to protect their snouts while foraging for fish among corals, even teaching the technique to their calves.
“They place a sponge over their nose and use it to dig through the seabed,” Ridgley explained. “It helps protect their faces from cuts caused by rocks or coral.”
In contrast, the humpback dolphins’ “sponge wigs” seem to serve no practical purpose — only to catch the attention of potential mates.
Listed as “vulnerable” under the National Environmental Protection Act, there are fewer than 10,000 adult humpback dolphins left worldwide. Scientists say understanding and protecting their behavior is crucial for the survival of the species.
So, next time you imagine dolphins gliding gracefully through the waves, picture this: a confident male dolphin donning his sea-sponge crown — the ocean’s very own display of style, charm, and courtship.
