Do anaconda have predators

Due to their sheer size and strength, adult Anaconda's have no natural enemies. No other animal in the rainforests is large enough to kill a full grown Anaconda. A Jaguar or a large Caiman may kill a small or adolescent Anaconda but an adult is ruled out as prey even for these predators. On the other hand, Anaconda's are known to kill even large Caiman's and Jaguars when they feel threatened.
