Signs of animals dying include stopping swimming, body stiffness and antenna changes.

1, stop swimming: When the little jellyfish is dying, it will become lazy and doesn't like swimming. Generally, it will lie quietly at the bottom of the tank.

2, the body is stiff: the main component of the small jellyfish body is water, which is composed of endoderm. Before they die, their bodies will become very stiff.

3, antenna changes: one or two days before the death of the small jellyfish, its antenna will begin to secrete reticular filaments.
