NOAA Fisheries responded to two pygmy killer whales (members of the oceanic dolphin family) stranded on shore near Sugar Beach, Maui on Tuesday.

According to NOAA, it also monitored four other pygmy killer whales that were seen swimming about 20 yards offshore.

Veterinarians at the scene assessed the health of the two stranded whales. 

Upon assessment researchers found a low number of an enzyme that indicated illness or malnutrition in the whales.

Researchers became concerned about the potential causes for the whales becoming stranded.

It was determined that the whales wouldn't be able to survive and the whales were then euthanized.
