20 de may. de 2024 · The evolution of jellyfish is a testament to the remarkable adaptability of life in Earth’s oceans. From their ancient origins to their present-day diversity, jellyfish have undergone a journey shaped by millions of years of environmental change.
17 de may. de 2024 · Climate change could mean an ocean dominated by jellyfish. Researchers say that in the future, jellyfish and other gelatinous zooplankton may be some of the few organisms to benefit from climate...
Hace 3 días · A new exhibition opens in Oldham this weekend and it’s all to do with Jellyfish. Jellyfish have drifted along on ocean currents for millions of years, even before dinosaurs roamed the earth.
