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

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

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).

Great for getting some Meat!

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

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

Good for cost raiding

Very fast but also very ugly looking.
