SAN DIEGO (CBSDFW.COM/AP) — They claim SeaWorld misled investors about injuries during its dolphin shows, now an animal rights group is asking the U.S. Securities and Exchange Commission to investigate.

People for the Ethical Treatment of Animals (PETA) said it sent a letter to the SEC saying the marine theme park had lied when it said no animals are injured during the shows.

The SEC declined comment.

The group known as PETA is a shareholder in the company and alleges that SeaWorld trainers have caused injuries when they stand on the dolphins.

It says veterinarians have found wounds and scars on dolphins at SeaWorld parks in San Antonio, Texas, California and Florida.

SeaWorld said in response that it treats its animals well and has rescued thousands. It calls PETA a radical group.
