The zoo's veterinary team uses scans to monitor animal health.

In the spooky spirit for Halloween, the zoo shared skeletal snapshots of some of the zoo's wildest residents.

Puerto Rican crested toad

Native only to Puerto Rico, the zoo says the Puerto Rican crested toad is a rare amphibian. Adding that the head has a distinctive bony "crest" above the eyes.
