    Many species of poison dart frogs derive their toxic compounds from ingesting mites! Even crazier, some molluscs like the Blue Angel sea slug (glaucus atlanticus) can ingest and weaponize the nematocysts from siphonophores like the Portuguese Man O’ War. Nature be crazy

    Isn’t that also how fugu gets its poison? I think the pufferfish grown on farms where their diet is regulated aren’t poisonous.

      TIL… Thank you, kind stranger, for making me curious enough to look further

      https://en.m.wikipedia.org/wiki/Fugu

      Researchers have determined that a fugu’s tetrodotoxin comes from eating other animals infested with tetrodotoxin-laden bacteria, to which the fish develops insensitivity over time.[10] Whether tetrodotoxin is sequestered from or produced by symbiotic bacteria is still debated.[11] As such, efforts have been made in research and aquaculture to allow farmers to produce safe fugu. Farmers now produce poison-free fugu by keeping the fish away from the bacteria – see § Aquaculture below.[10]
