There had only been two previous sightings of the species in the region, including one in Turkey and one off the coast of Gibraltar, on the southern tip of the Iberian Peninsula, said Scheinin.

The animal was caught by Palestinian fishermen and butchered, with video circulating on social media showing crowds of Gazan men in Khan Yunis pulling the enormous fish ashore.

Silent environmentalists

Animal rights groups, along with international marine biologists, were notably silent after the images emerged online.

“Regrettably, this doesn’t come as a surprise to me,” said Scheinlin. “They are so captive in their conception that ‘Israel is bad and the Palestinians are good’ that this won’t change anything.”

“It’s very sad,” said Adi Barash, CEO of Sharks in Israel, a nonprofit dedicated to shark conservation, noting that almost every animal that enters Gaza waters—including a rare giant sea turtle killed by Palestinian fishermen two decades ago—never returns. “Whatever is migratory will not pass through Gaza waters,” she said. “But we can’t expect that in Gaza they will care about preserving nature.”
