This is caviar from beluga whales:
Who or what are the eggs of this beluga sturgeon? It’s a fish. Who lays the eggs is:
It’s interesting to note that a sturgeon’s eggs may be extracted without killing it. This is how a lot of farmed caviar is obtained.
Rafael Cavacchini highlighted in your response that the caviar is made from the roe of the Beluga sturgeon, also known as white sturgeon, which may live up to 100 years and grow to be 7 meters long. This ancient fish most likely existed at the period of the dinosaurs.
Due to the destruction of its habitat in the Black and Caspian Seas, as well as indiscriminate fishing and the commercialization of its appetizing and coveted roe, which can eventually be surgically removed, preserving the life of the females, the availability of this tidbit has dropped by more than 90% in recent decades. However, this does not appear to be the case in most cases. As a result, they are on the verge of extinction.
Beluga, on the other hand, is found in the Artic and sub-arctic regions and is incorrectly termed White Whale. This moniker does not apply to toothed cetaceans.
