Hippopotami were associated with life, regeneration, and rebirth.

Weeks before Germany's May 1945 surrender in WWII, three babies were born to three Nazi prisoners. Remarkably, their mothers managed to deceive their Nazi captors and keep their babies alive. cbsn.ws/4aEnyDX
The Holocaust's youngest survivors: born in a labor camp, on a death train, and in a concentration camp
Eva Clarke, Hana Berger-Moran, and Mark Olsky are survivors born to survivors. During the Holocaust, their mothers were young Jewish women sent to concentration camps when they were newly pregnant.

This isn't shortread data, but alignments of genome assemblies with N50 > 100Mb. The plot is the # of bp per 100Kb window that are dropped because of missing data -- because those bp physically are not there in one of the other 25 genomes. This is what normal plant genomes look like, folks.
