The Oregon Humane Society is investigating deaths of marine animals at the Portland Aquarium, which opened in December.
The Oregonian reports more than 200 marine animals died this spring from starvation, infection, high temperatures, and animal-on-animal attacks. Among the casualties were bamboo sharks, sea horses, garden eels, sea stars, crabs and dozens of fish.
The aquarium's former veterinarian said it failed to properly quarantine new arrivals and routinely delayed emergency treatment to save money.
The death log kept by aquarium staffers was provided to The Oregonian by a former employee.
Aquarium owner Vince Covino says it provides animals the best health care possible and the death rate is consistent with what he's observed at other aquariums.
