Ocean Park wants to buy about 30 bottlenose dolphins from the Solomon Islands. But no one knows how many of these dolphins there are in the wild.

If numbers are low, it could be dangerous to take 30. So Ocean Park says it will give the Solomon Islands' government money to study how many dolphins there are in its waters.

If there are enough dolphins, the government says it will sell about 30 to Ocean Park. Critics say even if stocks are too low, the government will push for the sale of the dolphins to get the money. They want the study to be led by scientists not involved in the issue.
