Six relocated belugas have died, while causes remain unclear
The story at a glance
Six of the 30 belugas transferred from Marineland in July and August 2026 had died by 21 October. The deaths occurred at facilities in the United States and Spain.145
Findings for some of the whales show serious or potentially pre-existing health problems. Investigations do not establish a single cause for all six deaths, or show that the transfers caused them.123
The story in brief
What you need to know
- The six deaths are a substantial loss among the relocated belugas, but they do not by themselves establish whether the move improved or worsened the animals’ welfare overall.123
- Four of the deaths were at Shedd Aquarium, one at SeaWorld San Diego and one at Oceanogràfic València. The tally refers to belugas, not every cetacean transferred from Marineland.145
- Shedd’s findings identified longstanding digestive inflammation in Rain and Peekachu, and preliminary findings identified chronic liver disease in Osiris. External pathology experts said underlying disease may have increased Rain and Peekachu’s susceptibility to cardiovascular stress, which contributed to their deaths.12
- Oceanogràfic’s preliminary findings for Jelly Bean identified abnormalities that may have begun before her arrival in Spain. The investigation into her death was still continuing when the facility published its update.3
- A bottlenose dolphin, Echo, also died after being transferred from Marineland to Oceanogràfic. Echo is not included in the six-beluga figure.13
Conservation context
Why this matters
The deaths raise questions about the welfare risks involved in moving animals with health problems. An interviewed biologist described transport of sick animals as risky, while also saying that leaving them at Marineland was more dangerous; advocates criticised the transfers. The available veterinary findings do not settle the contribution of relocation or prior illness.124
The developing story
What happens next
Veterinary investigations into some deaths remain under way, including at Oceanogràfic. Updates on final findings and the condition of the surviving animals will help clarify what can be concluded about the losses and their ongoing care.23
Established evidence
What we know
- Shedd Aquarium reported on 9 October that its six surviving rescued belugas were eating their full diets.2
- Oceanogràfic reported on 13 October that its four other rescued animals were progressing favourably.3
- The sources agree that some deceased animals had serious health concerns, while findings so far do not provide one established cause for all six beluga deaths.123
Open questions
What we don't know
- What final veterinary findings will establish about causes and contributing factors in deaths where investigations were incomplete.23
- How the surviving belugas will fare as they continue adjusting to new facilities, caregivers and social groupings.23
- Whether receiving facilities will make clear long-term commitments about breeding and public-facing use of the transferred whales.1
