What causes the Caribbean monk seal to go extinct?
“Humans left the Caribbean monk seal population unsustainable after overhunting them in the wild,” said Kyle Baker, biologist for NOAA’s Fisheries Service southeast region. “Unfortunately, this led to their demise and labels the species as the only seal to go extinct from human causes,” he said.
Why are Hawaiian monk seals going extinct?
In the main Hawaiian Islands, the primary threats Hawaiian monk seals face are fisheries interactions, intentional harm by humans, and disease, particularly toxoplasmosis, which is now a leading cause of Hawaiian monk seal mortality and a growing concern in the populated main Hawaiian Islands.
How did Caribbean monk seals go extinct?
Caribbean Monk Seal Gone Extinct From Human Causes, NOAA Confirms. Summary:Overhunting by humans led to these seals’ demise, according to NOAA biologists. The last confirmed sighting of the seal was in 1952 in the Caribbean Sea at Seranilla Bank, between Jamaica and the Yucatán Peninsula.

Do sharks eat monk seals?
Deliberate killing of monk seals has also been a problem. Sharks are natural predators of Hawaiian monk seals, but during one unusual period, shark attacks at the French Frigate Shoals shot up, killing nearly a quarter of all pups born between 1997 and 2010. This kind of predation continues to be a concern.
