Dolphins Display Drug‑Like Play and Grief‑Driven Calf Carrying

Underwater footage captured for the BBC documentary "Dolphins – Spy in the Pod" shows groups of dolphins interacting with pufferfish. Producers describe the animals as "actuar de una manera peculiar, dando vueltas con sus morros y tocando al pez globo" and suggest the cetaceans enter a trance‑like state after ingesting the fish’s toxin, a behavior interpreted as drug‑like play.

In a separate incident off the coast of Perth, Australia, a dolphin known as Fraggle was filmed carrying the dead body of her two‑week‑old calf for several minutes. Researchers from Geographe Marine Research and neuroscientist Lori Marino said, "Está absolutamente claro que se trata de una madre que está de luto por su hijo," highlighting the strong emotional bonds and grieving behavior observed in cetacean groups.
