Members of the Project Jonas Cetacean Conservation Committee have revealed the temporary existence of 31 dead pilot whales. Rescue operations are continuing on Friday morning, the 18th, under the auspices of the New Zealand Government’s Department of Defense.

Volunteers allowed 5 Cetaceans stranded to return to sea, but could not confirm whether they were able to swim normally again. There will be more than 40 animals in the group affected by this new incident. The causes of these continuous strands off the north coast of New Zealand are unknown.

Defense Department spokesman Dave Winterburn said Coast Guard and volunteers had worked long hours to rescue the Cetaceans, but feared some of them would be out of the water for long.

Farewell Speed, a 16-mile-long peninsula, mostly made up of beaches, has been off the coast of a dozen pilot whales in the past 15 years.

The most tragic event occurred in February 2017, when nearly 700 of these marine mammals were trapped in the sand and eventually 250 died.

Scientists do not know why the beach is so bad. One theory is that saliva creates a shallow surface in the bay that interferes with the whales’ sonar navigation systems. It has not been ruled out that certain human activities or the occasional presence of boats may be associated with the diversion of these Cetaceans.
