October 23, 2023 — There are about 356 North Atlantic right whales left in the world, according to data released Monday from the North Atlantic Right Whale Consortium. That’s actually a bit of good news for the critically endangered species, signaling that the population may be starting to stabilize.
“After years of the population trajectory in being in steep decline, that decline is leveling out,” said Philip Hamilton, a senior scientist at the Anderson Cabot Center for Ocean Life at the New England Aquarium. Hamilton said he wouldn’t quite frame the population numbers as “optimistic,” though: “I guess I could say it eases the weight on my heart a little bit, but we have a long ways to go.”
Right whales still face significant threats. The leading causes of death and injury to right whales are entanglements in fishing gear and getting hit by boats; climate change and noise pollution are added stressors.
So far this year, researchers from the New England Aquarium have counted 32 injuries to right whales after they were hit by boats or entangled in fishing gear. There have also been two detected deaths of right whales in 2023: a 20-year-old male struck and killed by a boat and an orphaned newborn calf.
“Not only are human activities leading to the deaths of whales, but they’re also leading to these injuries that aren’t outright killing the whale, but they’re stunting their growth. They’re delaying reproduction in females,” said Heather Pettis, a research scientist at the Anderson Cabot Center for Ocean Life at the New England Aquarium. She said the whale population can only recover if their birth rates go up, while their death rates go down.
