WWII Shipwreck Saves Rare Monk Seals Off Albania

A torpedo-struck hospital ship from 1941 has become an unexpected sanctuary for one of the world's rarest marine mammals.

The Po, a World War II hospital ship that sank off Albania's coast after a British torpedo strike, now hosts over 80 species of marine life across its rusted hull. In August 2023, researchers captured footage of a Mediterranean monk seal resting inside the wreck's sheltered cavities, marking the first confirmed sighting in Vlora Bay since 1996.

Mediterranean monk seals number fewer than 700 individuals worldwide, making them one of Earth's most endangered marine mammals. They traditionally breed in quiet sea caves along Mediterranean beaches, but coastal tourism has pushed them into increasingly dangerous and isolated spots.

The shipwreck offers something these struggling seals desperately need: peaceful shelter. Its underwater chambers and protected spaces mimic the natural caves that human development has destroyed or disrupted.

"Shipwrecks like the Po are providing critical resting opportunities when natural habitats are fragmented," researchers wrote in the journal Frontiers in Ocean Sustainability. The study documented 28 fish species, squid egg clusters, and thriving algae colonies across the artificial reef.

The Bright Side

While climate change brings challenges, the Po wreck shows how unexpected structures can support wildlife recovery. Scientists found the wreck teeming with life, its surfaces covered in marine growth that feeds dozens of species.

The presence of invasive devil firefish from the Red Sea does complicate the picture. Warming Mediterranean waters are drawing these tropical predators northward through the Suez Canal, and wrecks may help them spread. Still, the monk seal discovery offers hope that creative conservation solutions can emerge from unlikely places.

Ancient shipwrecks scattered across the Mediterranean could provide a network of safe havens for monk seals pushed out of traditional breeding grounds. Each wreck becomes a potential refuge where exhausted seals can rest between increasingly rare undisturbed caves.

The footage from the Po proves these animals will use whatever shelter they can find when humans give them space to exist.
