Poisons f low in veins of great white sharks
CHARLOTTE – Great white sharks – one of the ocean’s most fearsome apex predators – thrive with toxic levels of poisons flowing in their veins, according to a new study by OCEARCH.
Researchers recently came to that conclusion after taking blood samples from 40 white sharks off South Africa, according to an April 3 report on OCEARCH.org. The samples revealed “alarmingly high levels of poisonous heavy metals, like arsenic and mercury, in sharks’ blood,” the report said.
“Despite levels of heavy metals that would be toxic to most other species, white sharks seem to show no ill effects,” said OCEARCH, a nonprofit devoted to collecting “previously unattainable” ocean data.
The fact that white sharks flourish with poison in their veins is one of the “tricks” the species has used to survive millions of years, the report said. “White sharks are incredibly tolerant to what would essentially be poison to other species.”
