I manged to get into a river because these dudes can levitate and don't take damage so the poor bobs saw the unspeakable as the loch Ness monster ate them with this long butiful neck of terror.

Put a grill on platform. Farm other plesiosaur for prime meat. Cook underwater

Beefy, powerful, fast, good lifter, supports platforms, can be tamed on foot with much less efort and risk than Mosas (still not easy). For sure this thing is the most versatile mount after Mosas, Quetzals, Wyverns and Mantis (oh boi, you NEED a Mantis).

If you have the tek under water stuff will not flood underwater so you can have ultimate water patrol unit.

Been breeding these and it's a pain. Have 4 pairs now and they are the cutest babies.

Great for getting some Meat!

These are my favorite water tame. Build a base on one and go wherever you want

Very fast but also very ugly looking.

Good for cost raiding
