Carnivorous seaweed was an aquatic carnivorous species of plant that grew in the oceans of the planet Hapes and used its tentacles to suffocate its victims. In 23 ABY, Jedi trainees Tenel Ka, Lowbacca, Jacen Solo, and Jaina Solo were nearly killed by a patch of carnivorous seaweed in the Hapan ocean when Ambassador Yfra sabotaged their wavespeeder. Later, the young Jedi drove their wavespeeder into some carnivorous seaweed to kill a group of Bartokk assassins who were following them. Those assassins were sent by Yfra to kill the matriarch of Hapes, Ta'a Chume, so Yfra could assume the role of Hapan monarch.
