The sunfish

The sunfish is the dumbest animal alive. It's a giant, gelatinous creature with a tiny brain and a bizarre evolutionary strategy of eating low-nutrient food and being covered in parasites, yet it thrives.

  • ๐ŸŒ Its evolutionary strategy is to be large, weak, eat low-nutrition food, and grow fast, despite being infested with parasites.
  • ๐Ÿชจ Sunfish have incredibly thick skin, up to 15 cm, making them tough but not very nutritious.
  • ๐Ÿฆ  They are a mobile ecosystem, hosting around 50 species of parasites, and even their parasites have parasites.
  • โ˜€๏ธ They sunbathe on the surface to warm up and to allow seabirds to clean their parasites.
  • ๐Ÿ‘ถ Female sunfish lay hundreds of millions of eggs, but 99.999% of offspring die.
