The shark-bite attacks on otters are essentially “taste tests” made while hunting, Harris said.
“This would explain why the majority of the otters collected have a single bite mark,” he said. “These bites are more investigative.”
After a shark realizes an otter won’t make a good meal, they let go and move on, Harris said.
Shark attacks on otters are part of nature, Harris said, but they concern researchers who want to preserve healthy populations.
“It becomes complicated,” he said. “They are both protected species.”
