Found two Yupik dictionaries but neither had 'akhlut'. Then found the article below:

Location Ice floes around the Bering Sea
Akhlut are shapeshifting spirits from Yupik myth. They appear as
either orcas or as wolves, and live among ice floes around the Bering
Strait. They are often depicted as a hybrid between an orca and a
Appearance In the original folklore, akhlut were gigantic orcas who could shapeshift into equally massive wolves to hunt on land.
In traditional art they are usually depicted in mid transformation,
with the features of both wolves and whales. Most modern
interpretations portray them as creatures that are perpetually half
wolf, half orca rather than shapeshifters. They are generally
amphibious. An occasional variant of the creature appears as a beluga
whale, and can transform into a reindeer to traverse on land. It is
unclear whether this variation is carnivorous or not.
Behavior Akhlut are known for their ferocity, and they hunt humans and animals alike. When hungry, they become wolves and run
across the land searching for prey. Once they have eaten their fill,
they return to the water and assume their orca forms once more.
Wolf tracks leading to or from the ocean are an indicator that the
animal may be nearby.
Anthropological information Nelson (The Eskimo About Bering Strait) claims that the creature is called Kăk-whăn'-û-ghăt
Kǐg-û-lu'-nǐk, and in orca form it is known as akh'-lut, and in wolf
form as kǐg-û-lu’-nǐk. These may be mistranslations or alternate
dialects, as the central Yupik romanizations for "orca" and "wolf" are
"arrlug" and "kegg'luner" respectively. It's unclear what the word
"Kăk-whăn'-û-ghăt" might mean. At any rate, it appears the name these
creatures are most well known by is simply a corruption of the Yupik
word for "orca".
