Eight gigantic sperm whales were discovered on a German beach on Feb. 1, adding to the rising death toll in the region.
The discovery came just weeks after 15 dead sperm whales were found across northern Europe.
The latest bodies washed up in the mudflats of a restricted area of the Wadden Sea national park, the Schleswig-Holstein regional environmental authority said in a statement.
The authority said that during migration, the animals “mistakenly wind up in the shallow and nutrient-poor North Sea,” making it harder for them to use their acoustic orientation to navigate.

But wildlife protection groups also blame the underwater noise from sea traffic and oil platforms for interfering with acoustic signals, reported the Daily Mail.
Without citing a specific group, it said that researchers at the University of St Andrews have found that the noise made by offshore wind farms can interfere with a whale’s sonar, and can in tragic cases see them driven onto beaches where they often die.
Sonar from submarines can also confuse or deafen whales.
On the other hand, researchers with the Zoological Society of London in Regent’s Park, who have taken the lead in studying the recent rash of deaths, say it’s unclear what’s causing the whales to enter the North Sea.

“In terms of the sperm whale events, we will have discussions with our Dutch and German colleagues,” Rob Deaville, the program’s project manager, told the Guardian.
“We’ll look at what may or may not have been going on. It may be that after months of research we are none the wiser as to what caused them to come into the North Sea in the first place. I suspect this is a strong possibility.”
After researchers take samples from the newest set of whales, the animals will be taken to nearby landfills.
