The privately owned San Antonio Aquarium, cited little more than year ago by federal authorities for failing to meet animal-care standards, has again been called out by the U.S. Dept. of Agriculture — this time for the death of a female porcupine. A San Antonio Aquarium employee on July 28 discovered the deceased porcupine after the animal escaped her enclosure and entered the habitat of a male porcupine, according to the new USDA citation. The male then impaled the escaped female with his quills, the Aug. 1 document notes.
