 Scientific expeditions were also in fashion (not the least the recently completed voyage of HMS "Beagle" 1831-36 with Charles Darwin on board) and the Danish King Christian VIII had a keen interest for natural sciences.Thus on board "Bellona" was the 41 year old naturalist Henrik Nikolai Krøyer.Almost nothing is known from direct sources about Krøyer's work on "Bellona", but indirectly from his later scientific publications it is evident that he collected a wealth of animals, in particular crustaceans.
