Haus des Meeres to host tour on animal sleep strategies

The Haus des Meeres in Vienna will host a specialized tour titled ‘ZooLogisch! – With Full Fins into the Weekend’ on October 2, 2026. The one-hour guided session will examine the diverse sleep and rest strategies utilized by various animal species.

Key topics include how certain shark species, known as ram-ventilating sharks, must maintain constant movement to facilitate oxygen intake through their gills, effectively resting while swimming. The tour will also explore how animals like the Komodo dragon manage rest periods outside of traditional nighttime cycles, and how marine life adapts to rest underwater without drowning.
