NEW ORLEANS (AP) - Several environmental groups are suing BP PLC for the oil spill's toll on endangered species of wildlife in the Gulf of Mexico's ecosystem.

The federal suit filed Wednesday in New Orleans by Defenders of Wildlife, Gulf Restoration Network Inc. and Save the Manatee Club Inc. accuses BP of violating the Endangered Species Act.

The groups are seeking a court order requiring the company to mitigate the oil spill's impact on wildlife and restore their habitats.

The suit says the Gulf has at least 27 endangered or threatened animal species, including sea turtles, whales and birds.
