Almost half the available space has been reserved for living nature. De dioramas on life in "Pool and Puddle", "The Forest", "The Heather Moor" and "Dune and Beach" draw a lot of attention. The imitated biotopes also show a view under the water surface (including fish), hidden birds'nests and vegetations. The longer one looks, the more there appears to be seen.
A large collection of birds, a renewed mammals display, a presentation on the life of plats and a butterfly collection complete the exposition.
A spectacular object is one of the last sea eagles, shot in 1853 at Wouwse Plantage. This impressive bird, nichnamed "flying door", has recently returned to the Netherlands, and now nests in the Oostvaardersplassen.
A special owls display shows various owls, even an eagle owl which is rarely seen in the wild. The eagle owl skeleton shown is an acquisition made in 2006. The beautifully preserved skeleton shows clear parallels with the human skeleton.
In the original display cases along the walls many animals, large and small, indigenous and exotic, are shown. At the side of a conpicuous hog is a tiny deer, there is a lynx, various hares, a bull frog (which, of course, is not a mammal), a badger, and a number of skulls including those of apes and monkeys.
This exposition is housed in five displays on the back wall and two free standing display cases. On eight lighted panels subjects from butterfly biology are presented. On seven smaller panels a survey is given of the most numerous indigenous butterfly families, by menas of mounted butterflies from the collection. In the free standing displays a number of drawers with non-indigenous butterflies are shown. Special is the panel with the so-called "iridescent burtterflies". The butterfly collection was acquired in 1998. It consists of 14 large and 14 smaller drawers butterflies, bugs and beetles, amounting to approx. 500 animals. Not all drawers are shown.
Mightily interesting to some, to others lugubrious: the sometimes weird organisms preserved in alcohol or formaline. The fluid enables us to preserve and show vulnerable organic tissues. Unborn animals, snakes or fishes can withstand time in this way.
This exposition is shown in the column display at the East end of the museum room. A screen divides the case in two parts. The North side houses a number of vertebrate marine animals, the South side shows some invertebrates.
A shark jaw, a ray, a sea horse, the impressive jaw of a sawfish, a dolphin skull and a Christ fish give sufficient occasion for wonder.
Among the invertebrates the European sea lobster stirs the imagination. Corals and shells also belong to the invertebrate marine animals.
