A manatee who died in a Florida aquarium earlier this year suffered fatal injuries caused by sex with the aquatic mammal’s brother, officials said.

An ailing manatee that was found and rehabilitated in Texas late last year is now in Florida after being flown from Texas on a cargo plane.

Rescue groups in Texas pulled a cold-stunned manatee from a Texas City canal in early December.

The discovery of a Florida manatee with “Trump” written on its back has prompted an investigation by state and federal wildlife authorities, The New York Times reports. Fish and Wildlife Service said according to The New York Times. “It’s a crime to interfere with these creatures, which are protected under multiple federal laws.”State and federal wildlife authorities were investigating after a manatee with “Trump” etched on its back was spotted in Florida on Sunday. Manatees, which are the unofficial mascot of Florida, are also protected by the Florida Manatee Sanctuary Act of 1978, which states that “it is unlawful for any person, at any time, intentionally or negligently, to annoy, molest, harass, or disturb any manatee,” according to the Florida Fish and Wildlife Conservation Commission.
