DESCRIPTION:"Dian told me they were tandorazes, or tandors of the sea, and that the other, and more fearsome reptiles, which occasionally rose from the deep to do battle with them, were azdyryths, or sea-dyryths--Perry called them Ichthyosaurs. They resembled a whale with the head of an alligator." (At the Earth's Core by Edgar Rice Burroughs)

NOTES: The "sea tiger" is the plesiosaur of the seas of Pellucidar.

HISTORY: The Seas of Pellucidar are crowded with such creatures. To say the least, swimming is not a big sport in The Inner World.
