Aquatic Special Ability Description Help

I was working on doing a Fantasy Grounds conversion of the Conan the Barbarian book for use with the new Conan ruleset and ran into a problem. as I couldn’t find a description for to special abilities,
A few foes in the Conan the Barbarian book have an ability title “Aquatic” but no description is given of the ability. Looking through the various other Conan books I own I found the same problem was in other books. Some foes in a few cases in other books did give an description for aquatic, but the way it works differed depending on the foe or were you looked in certain book.

I also couldn’t find a description for an ability titled Speech that another foe in the Conan the Barbarian book had.

So how do these two abilities work?
