Another gray whale has been found dead in Alaska.

The National Oceanic and Atmospheric Administration confirmed Wednesday that a fourth gray whale was discovered dead near the Clam Gulch State Recreation Area on the Kenai Peninsula.

The whale was found by a family fishing for herring. Marine mammal experts examined the family's photo and confirmed it was a gray whale.

NOAA Fisheries says the whale was young and estimates its length to be between 20 and 24 feet. Gray whale calves are born at about 15 feet, according to NOAA.

Dr. Kathy Burek Huntington, a pathologist with Alaska Veterinary Pathology Services, says the whale is small and skinny.

Researchers hope to perform a necropsy on the whale, but tides in the Cook Inlet are currently too high to collect any tissue samples.

NOAA says Alaska sees up to three gray whale strandings between January and May. Gray whales have washed up throughout Alaska in Kodiak, the Turnagain Arm and the Copper River Delta.
