'Sea monsters' in the Bible

And God created the great sea-monsters, and every living creature that moveth, wherewith the waters swarmed, after their kind, and every winged bird after its kind: and God saw that it was good.

Thou didst divide the sea by thy strength: Thou brakest the heads of the sea-monsters in the waters.

Praise Jehovah from the earth, ye sea-monsters, and all deeps;

Even the sea-monsters draw out the breast, they nurse their young ones: the daughter of my people is become cruel, like the ostriches in the wilderness.

creatures of every kind, beasts, birds, reptiles, and sea-monsters, are frequently tamed by human industry.
