Palestinian fishermen found an unsettling number of dead and bloody Mobula Ray fish washed up on the shores of Gaza City’s beach on Thursday, according to the U.K. based Daily Mail.
A local video report stated that it was the first time the fish have been spotted on the beach for six years.
The Mobula Ray fish resemble the manta ray which are in the same animal family and can reach up to a scale of 17ft and weigh more than 12 stone.
One of the world’s leading experts, Robert Rubin of Santa Rosa Junior College in California, told the Daily Mail that “Mobulas often travel in huge schools of thousands of animals and also leap from the water and twist in the air.”
Rubin said that “this observation is strange to me and unknown to me as well. I have worked in the Gulf of California for many years where there are abundant Mobula schools and I have never seen a mass stranding,” These animals seem to have blood on their pectoral fins - which may have come from slapping something - boats, rocks, sand, each other?”
However, Rubin said that without being able to see the fish and looking further into other causes including stomach contest and the condition of their gills, he would not be able to determine what would have caused the beaching of these creatures.
Large underwater noises or electrical signals may have caused some state of disorientation but that is only a guess on my part,” he added.
