The whales' population was seriously depleted by whaling up until the practice was banned in 1985, the agency noted. Humpback whales can weigh up to 40 tons, be as long as 60 feet, and live up to 90 years old. The massive sea creatures live in all the world's oceans, according to the agency.
The agency said while more research is needed to fully understand the cause of the deaths, 40 percent of whales that underwent necropsies showed "evidence of human interaction, either ship strike or entanglement." The agency declared a "Humpback Whale Unusual Mortality Event Along the Atlantic Coast" in April 2017.Ī total of 23 humpback whales have been stranded so far in 2023, including five in New York and seven in New Jersey, the agency reported. Humpback whale deaths on the East Coast have been on the rise since January 2016, according to National Oceanic and Atmospheric Administration records. The two strandings were not related, according to the agency.
