World Jellyfish Day
They have no brain, bones, or heart, but jellyfish have been plowing Earth's oceans for half a billion years. Today, on World Jellyfish Day, these hypnotic creatures receive a well-deserved recognition under the sea. The day seeks to protect their habitats against threats such as pollution, excess nutrients, and ocean acidification.
With transparent bodies and tentacles that float to the rhythm of the currents, jellyfish seem to dance in the water. Some glow in the dark, such as those in the Pacific off Guerrero (Mexico), and others, such as the so-called "immortal jellyfish", can restart their life cycles.
They are essential for marine balance: they feed turtles, sunfish, and seabirds. In Spain, especially in the Mediterranean, you can see species such as the Pelagia noctiluca, with pink and luminous tones, or the curious "fried egg jellyfish", whose appearance is reminiscent of this familiar dish. To admire them in their natural surroundings is to discover an ancient beauty that still pulsates beneath the waves.
