Beck-tori
this immense, aquatic parasite evolved on the planet Nam Priax, but has been spread to several other worlds over the history of the galaxy. Resembling a extremely large, elongated leech, a beck-tori was distinguished by its huge mouth. The mouth was surrounded by a mass of thick spines, which were used to grasp prey and begin to grind it up before passing into the throat. Like most parasites, the beck-tori latches onto a host, using its mouth spines to grasp and tear at the host's flesh. Once buried inside the host, the beck-tori begins to deposit its larvae, which grow by consuming the host from the inside out. While an adult beck-tori can exist out of the water, this is not their most unusual trait. All beck-tori had a strong connection to the Force, and could actually use it to heal themselves. The Old Republic tried to ensure that the beck-tori never made it off Nam Priax, but several infestations ddid occur on other planets. Most notably, Mon Calamari suffered an outbreak of beck-tori, which took more than fifty years to finally eradicate.
