Beauty Inside - Coloring Bone

Seodaemun Museum of Natural History

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

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.

Korean rockfish
It is a predatory species and popular quarry for anglers. They become matured adults about 3 years. They breed via internal fertilization.

Blackfin seabass
It is a species of Asian seabass native to the western Pacific in the coastal waters of Japan, South Korea.

Kammal thryssa
This is one of the Engraulidae fish. The distinct difference between the anchovy, is having sharp keeled scale before the anal fin.

This specimen collected by the Jukbangyeom fishing. This is a traditional and eco-friend anchovy fishing method.

Spotnape ponyfish
They found in shallow coastal and brackish waters in schools. Their mouth could extend forward because of elastic snout.

Flathead goby
Flathead goby has only one dorsal fin located at the latter part of body.

Surfperch is viviparous, female carries the developing young.

Blackhead seabream
Blackhead seabream is one of the most popular fishes for game Their sex change occurs about age 5.

Brushtooth lizardfish
Brushtooth lizardfish have large mouth extending beyond eyes. Many teeth are in the both jaws.

Grass puffer
The grass puffer is the smallest species of Tetraodontidae family in Korea. They cannot be eaten because of fatal tetrodotoxin.

Seaweed pipefish
Seaweed pipefish grows up to 30 cm length. Its habitats are commonly around the eelgrass bed.

Olive flounder
This is the most common flatfish raised in aquaculture in Korea. Right eye migrates to the left side of the body as a process of metamorphosis as it grows from larval to juvenile stage.

Pacific sandlance
Pacific sandlance is found in sand bottoms. They take summer hibernation when high water temperature season.

Indian perch
Indian perch has 10 to 12 bands on sides of body. The number and width of these bands varies with habitat. It is one of the mouthbrooder fishes.

Chum salmon
Chum salmon have the largest natural range of any Pacific salmon, and undergo the longest migrations. The name varies according to the developmental stage.

The pictures shows translucent bamboo leaf shaped conger eel larva. Fish belonging to the order Anguilliformes begin life as flat and translucent, called leptocephalus.

Ocellated spot skate
This chondrichthyes is a bottom-feeding carnivore that consumes mainly shrimp, fishes, and crabs.

Red barracuda
This predatory fish has sharp-edged teeth in the large jaws. has a long and sharp snout. its body shape is also as sharp as torpedo.

Chameleon goby
It is native to marine and brackish waters along the coast of Korean. It has clear two black band from head to tail. These band can be shown in three direction.

The adult stickleback males build, guard and aerate the nest where the eggs are deposited.

Korean chub
Korean chub is one of korean endemic freshwater fish. They distribute all streams in Korea and prefer to upstream.

Largemouth bass
Juvenile largemouth bass can adjust their feeding habits to obtain the necessary amount of energy needed to survive. This ability allows them to be successful as invasive species.

Black tetra
Black tetra is a freshwater fish of the characin family. It has two prominent black vertical band just posterior to the gills. This is a common ornamental fish.

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. Eary developmental stage, they are very small, transparent and unable to swim against the current. They are plankton. Through a series of periodic shedding, young curstaceans turn into the adult forms.

Hermit crabs
These crabs usually carry an empty gastropod shell.

Longtail tadpole shrimp
It is a freshwater crustacean, resembling a miniature horseshoe crab. It is found in freshwater ponds and pools.

Four-footed animals
Before insects flying the sky, amphibians walking with four-foot that got into the land during the Devonian. There are huge differences in structures between swimming fins and walking legs. We cna find some interesting internal structures that being shared with mammals including humans.

It spends a major portion of its lifespan on the trees. Many tree frogs can change their body color for better camouflage.
