Thousands of cuttlefish mysteriously washed up on Santa Maria off Coronel, Chile on January 12, 2016.

The cause of the mass die-off remains unexplained.

The animals appeared in the South Island Harbor.

Scientists have started insvestigating the possible causes for this mysterious and apocalyptical mass die-off.

First images of this mass kill were widespread by Mayor Leonidas Romeros on Twitter.

    

Toxicological tests are now underway.

While it may be natural, this cuttlefish mass die-off may also result from water contamination.
