'Died' in the Bible

a third of the living creatures in the sea died, and a third of the ships were destroyed.

The name of the star is Wormwood, and a third of the waters became wormwood. So, many of the people died from the waters, because they had been made bitter.

The second poured out his bowl into the sea. It turned to blood like a dead man’s, and all life in the sea died.
