Marine megafauna is endangered

The marine megafauna is in serious trouble. Researchers at Swansea University have recently discovered what traits could threaten its extinction. According to them, megafauna is marine creatures living in seas or oceans with a bodyweight exceeding 45 kg. The particularly endangered megafauna includes many species of sharks, stingrays, whales, seals, sea turtles, emperor penguins, clams, squid, and octopus. Some of the features of these animals make them particularly vulnerable to extinction. Scientists warn that one in five oceanic species may disappear by the end of the century.

“This is a warning that we must act now to reduce human’s increasing pressure on the sea megafauna, including climate change while ensuring the recovery of the population,” said biologist at Swansea University. The survival of these animals is important because they play a key role in the marine ecosystem. They consume huge amounts of biomass, transport nutrients, and modify habitats through their behavior.
