This substance, hipposudoric acid, is believed to have antiseptic and sunscreening properties. The skin of hippos dries out quickly and cracks, which is why both species spend so much time in water.

Pygmy sunfish Pygmy sunfish Elassoma is a genus of freshwater fish, the only member of family Elassomatidae and suborder Elassomatoidei of order Perciformes. The type species is "E. zonatum," the banded pygmy sunfish. The Elassomatidae are known collectively as pygmy sunfishes, but are not true sunfishes, which are members of family Centrarchidae. Some researchers believe they are related to sticklebacks and pipefishes (order Syngnathiformes) rather than Perciformes. The pygmy sunfishes grow to a maximum overall length of .
