Oceanic Titans: The 10 Largest Marine Creatures in History
The piece explains why the ocean fosters gigantism—buoyancy lightens bones, thermoregulation favors larger bodies, and deep-sea energy sources support long growth—and then surveys 10 of the largest marine creatures, from the living blue whale (up to ~33 m) and fin whales to extinct giants like Megalodon, Perucetus colossus and Ichthyotitan severnensis, with notes on debated sizes (e.g., Nanaimoteuthis haggarti) and the inclusion of extraordinary coral colonies as massive ocean-scale structures.
