Jaguar (animal)

A jaguar was an Earth mammal native to at least South America. A large, wild cat (also see Lion), it was hostile to humans. The Second Doctor, John and Gillian once put a jaguar into a trap to harass any men who fell into it. This "jaguar trap" was a part of a larger scheme to defend one village from another.

Cultural references to jaguars
In Brazil, the Fifth Doctor and Turlough once met a woman named Ileana de Santos who took on the spirit identity of a jaguar. She possessed a jaguar hide which connected her to her avatar. (BFA: Loups-Garoux) Later, on the planet Dewyn, the Tenth Doctor and Martha encountered a vast collection of artefacts from Earth at the Ancient Worlds Theme Park. At one point, they needed to hide from some approaching thugs, so Martha wore a jaguar costume that the park was selling in their "Aztec Zone". (DWBIT: Inhuman Sacrifice)
