On 9 September, in front of a sold-out audience of 350 spectators, Hannes Jaenicke and Friederike Kremer-Obrock shared their experiences of ocean conservation. Against the magnificent backdrop of the Gasometer Oberhausen, the actor, documentary filmmaker, and environmental activist made it clear in discussion with the chairwoman of ElasmOcean e.V.: We must do more to protect our oceans and the animals that inhabit them! Literally on duty for sharks, polar bears, dolphins, sea turtles, salmon, and currently: "Im Einsatz für den Oktopus" (On Duty for the Octopus).

To accompany his current documentary "Im Einsatz für den Oktopus", ElasmOcean has published an octopus booklet, which spectators were able to collect from our information stands. It is available in the download section of our website, containing everything worth knowing about this fascinating species. To the delight of the attending ElasmOcean team, many visitors went home at the end of the evening with a booklet signed by Hannes, following great applause and consistently positive feedback. Our thanks go to the curator of the Gasometer, Jeanette Schmitz, and her team.

The documentary by Hannes Jaenicke can be streamed in the ZDF-Mediathek and will be broadcast on ZDF on 16 September 2025 at 22:15.
