For me when I was trying to rescue my dinos from redwood and i went with my Parasaur and i got attacked by these guys so i went home and the leech was on my screen instead of on the Parasaur so i called my cousin but he was no help(sorry if you read this lucas)and it turned out when i removed the leech from the Parasaur it was gone from my screen so I think when there is a leech on your screen but theres one on your dino then I think you just remove the leech from your dino and it will probably be gone from your screen hope this helps
