sperm whale
"The problem hadn’t gone away, only now there were thousands of bits of problem spread for miles around."
Marine researchers in Scotland called the discovery both "stunning" and "shameful."
Officials from New Zealand's Department of Conservation made the "heartbreaking decision" to euthanize the whales.
Plastic bags, ropes, fishing nets and a drum were all found lodged inside the juvenile off the coast of southeast Spain.
WHAT'S HAPPENING
New research suggests sperm whales can use their huge heads as battering rams against ships and each other.
Fossils discovered in the 1800s were initially thought to have belonged to a walrus.
