The critically endangered vaquita, the world's smallest porpoise and native to Mexico's Gulf of California, has been imperiled by illegal gill net fishing for an endangered fish called the totoaba, whose bladder is highly valued in Asia.
The alert, the IWC said, stems from its belief that a new mechanism is needed "to voice extinction concerns for an increasing range of cetacean species and populations."
"The extinction of the vaquita is inevitable unless 100% of gillnets are substituted immediately with alternative fishing gears that protect the vaquita and the livelihoods of fishers," it said.
