Dissections or making dried bone specimens help us to understanding inner sturctures of animals that have endoskeletons like a human. We can observe the inner structures through th transparent muscle and color-stained bones. It is useful to explore deeply inside of very tiny specimens or larval and juvenile fishes. This exhibition gives us one of the artistic looking of scientific experiments
Fish
Bony fish living underwater have cartilages as well as spines being originated from cartilage. After hatching from eggs, the sturctures and shapes of inner skeletons of fishes change with their developmental stages. We can see the most complex skull structures using coloring bones.

Invertebrates
One of the most varied dividing invertebrates which lives underwater with hard layer covering the epidermis of them is the Crustacean. They protect their body with cuticle layer from their predators.
