SEATTLE, Wash. — The Southern Resident orcas are struggling to survive, according to a census from the Center for Whale Research.
It revealed that just 74 Southern Residents remain.
You may remember just a few weeks ago, marine biologists celebrated the birth of a new calf.
However, the census says that three have died – two male orcas and one orca calf – since last July.
Scientists have called the orca’s mortality ‘death by a thousand cuts.’
The killer whales are facing a slew of environmental issues such as toxins in the water, increased vessel noise, and a dwindling salmon supply.
Researchers involved in this year’s census say that without sufficient prey abundance, the Southern Residents will ‘simply not be able to sustain population growth.’
