It will attacks rafts so be carful coming across one on a boat.
Also the Alpha Albino Leedsichthys Will give you raw prime fish me when you scrape meat off of it, and killing it will give you The Captains Hat Skin
When I was going to herbivore island I ran into two of these that were right next to each other. I only survived by staying next to the shore, they stay out in open water so doing this is safe. Make this higher for new players
Leedsicthy always spawn on your way to herbivore island or if your passing stonehenge. If you see them at Stonehenge kill with a pick because they are beached. It's so worth it. I've killed at least 4 0f them between herbivore island and Stonehenge and 1 alpha in 2 days with an icthy 200. The alpha fight was scary because he swam off and couldn't see him so I aggroed him with my raft and killed it in 2 bites then me in one.
