SAN FRANCISCO — Lawyers with Covington & Burling are part of the latest attack on SeaWorld over allegations that the park mistreats orca whales used in its shows.

A complaint filed Monday in San Francisco Superior Court claims the park duped visitors into buying tickets by falsely portraying its orcas as healthy and stimulated. The company’s website, television commercials and even the SeaWorld Parks and Entertainment Inc. logo misled consumers into thinking the whales thrive in captivity just as they would in the wild, the suit states.
