The beluga, also called the white whale, is a mammal in the whale group[5][6]. In the United States it is native to Alaska, and one group of belugas is listed as Endangered under the Endangered Species Act[3][1].
Conservation status
Worldwide, NatureServe ranks the beluga G5, which means Secure[2]. In the United States the national rank is N3, which means Vulnerable[7]. The IUCN Red List category recorded by NatureServe is Least concern[8]. Under the Endangered Species Act, one listed group of belugas has the status Endangered, listed April 13, 2011[1]. International trade is controlled under CITES Appendix II[9].
Where Beluga lives
NatureServe lists the beluga as native in one US state, Alaska[3]. Observation records on GBIF come mostly from Alaska, New York, California, Massachusetts and New Jersey[10]. Those counts follow where people look and report, not where the animals live.
- Native
- Introduced
- Extirpated or possibly extirpated

Habitat
NatureServe records these habitat types for the beluga: big rivers, bays and sounds, tidal mouths, open ocean and near shore[12]. The notes say it uses the open ocean and also shallow coastal waters[13]. In summer it uses the shallow estuaries of large rivers[13].
- Big river
- Bay/sound
- River mouth/tidal river
- Pelagic
- Near shore
Size, diet and lifespan
Adult belugas eat fish and animals without backbones, such as squid and octopus[14][15]. The diet is estimated at 60% fish and 40% invertebrates[16]. Prey named in the notes includes capelin, cod, herring, smelt, salmon and sculpin[15]. A female usually has one young at a time[17]. Gestation lasts 416 days[18]. Females reach sexual maturity at 1,644 days of age[19]. The longest recorded lifespan is 40 years in captivity[4].

- 40% invertebrates
When to look for it
NatureServe lists the beluga as a local migrant, and populations can differ[22]. Its activity pattern is recorded as circadian, which means it follows a daily cycle[23]. GBIF records for the United States fall mostly in May, September and October[24]. Records show when people look and report, not how many animals there are[24].
