- Fish

Genealogy belong to vertebrate pisces in taxonomy. Fishes spend their whole lives in the water. Fishes keep the balance and move back and forth, right and left using fins. They are gill-breathing animals in the water. Therefore whales and dolphins which are pulmonary respiration animals, amphibians whose adults have feet as frogs and salamanders, and invertebrates like cuttlefish, octopuses, shellfish, sea cucumber, ascidian, jellyfish are not fishes. 13,000 species live in the world and 2,000 species live around korea. Fishes appeared in fresh water then adapt to seawater. Ordinary fish can't live in fresh water and seawater but salmons, sweetfish, eel, goby, mullet, etc. live in both. Exhibition are swellfish, smelt, shark, bass and etc.

- Diorama of seawater fish in korea

Fish appeared at the end of the Paleozoic era 450 million years ago. There are 50 orders, 445 families, and 21,723 species of fish now. In korea there are 35 orders, 187 families, and 902 species of fish, 155 species of which are freshwater fish. West Sea is wholly made up of tideland and continental shelf. Its ebb and flow differs harshly with about 150 kinds of marine fish. Mainly Clupeidae of Clupeiformes, Sciaenidae of Perciformes, Pholididae, Callionymidae, Gobiidae, Pleuronectidae of Pleuronectiformes, Cynoglossidae, Soleidae and Tetraodontidae of Tetraodontiformes exist. Also, South Sea is made up of many islands, making an archipelago. As cold current and cold current cross over each other, warm temperate fish and hot temperate fish co-exist. Mainly skate of Chondrichthyes, banded houndshark etc., and Engraulidae of Clupeiformes, Synodontidae, Scorpaenidae of Cottida, Synanceiidae, Triglidae, Platycephalidae, Serranidae of Perciformes, belted beard grunt family, Carangidae, Sparidae, Labridae, Uranoscopidae, Gobiidae, Pleuronectidae, Soleidae, Monacanthidae of Tetraodontiformes, and Tetraodontidae exist. And as East Sea has deep average sea depth, Cottida, which easily adapt to deep sea and cold sea area, and economically effiecient file fish, mackerel, cod, herring, pollock, atka mackerel etc. exist. Ulungdo is influenced by East Sea's warm current, which result in pineconefish, silk sculpin, red tilefish, sea chub, cold porgy that often appear in Jeju Island and Pusan. On the other hand, as Jeju coast has warm current and coral on South sea zone, over 300 fish are reported, more than other sea zones. Mainly Moronidae, Carangidae, opaleye family, Sciaenidae, flagfish family, Pomacentridae, Scorpaenidae, Platycephalidae, which are warm fish exist. This display of sea animals is made from collecting Korea's represantative 60 kinds of fish and 17 kinds of Crustacea from every shore of Korea and making them into specimen. By this ecological display, Sea Fish's distribution and classification can be seen at a glance, helping the study.

- Shark

overall designation of Chondrichthyes Lamniformes. Distributed among open sea of the world, from cat fish which is 40cm to whale shark which is 18m, size is varied among kinds. Body is divided into 4 parts, which are head, trunk, tail, fin. Its shape is pyramid. Fin is generally developed, and some kinds' dorsal fin has strong thorn on it. On Male's vental pin is copulatory organ which looks like a stick, and it becomes semen's pathway when copulating. Tailpin's top and bottom is asymmetrical, with upper mouth side longer than the other. Surface of body is covered with squama placoidea , so when touched, it feels very rough. Mouth is under the body, and some species have path between nose and mouth which connects nostrils with mouth. Eyes are on either side of head, and behind those are 5 to 7 pairs of gill slits. Right behind the eyes is a spout. A skeletal structure is wholly made up of a cartilage, and teeth are so well developed that it becomes main point of classification. The intestinal tract looks short but as it is a spiral, it actually is long. Blood vessel system is closed blood vascular system, which blood only pass through blood vessels, its heart has 1 atrium and 1 ventricle with conus arteriousus.

- Korean Fish(Immersion)

Displays dace, Korean spined bittering, oriental weatherfish, Chinese ninespine stickeleback, slender bitterling, Japanese icefish, Korean torrent catfish, Arctic lamprey, etc.

- Korean Crustacea

Crustacea are Arthropoda which live underwater, and breath water with gill. Body is divided into 3 parts, head, abdomen and chest. Each part is made up of segment. As one becomes higher in class, head and chest unifies.

- Shells

Mollusca generally means shellfish which has a shell and gastropods. Mollusca includes monoplacophora, polyplacophora, pelecypoda, gastropods, scaphopoda, cephalopoda(cuttlefish), etc. Shells usually excludes polyplacophora, monoplacophora, cephalopoda. Korean Mollusca have been reported 185 families 479 genus 907 species.

- Many corals

Coral is a general term of coelenterata coral class octocorallia coral family animals. Includes red coral, pink coral, white coral.

- Insects of the world

1. Insects of the world Anthropoda which has 1 pair of antenna and 3 pairs of wings with head, abdomen and chest appeared on earth. Until now, known insects are 900 thousand(Korea 12 thousand) which makes up 4/5 of all known animals on earth.

- Korean insects

Displays long-horned bettle, diving beetle, oriental long-headed locust, grasshopper, dragonfly, hawk moth, cicada, etc.

- Butterfly

General term for Insects of Lepidoptera that acts on daylight. Lepidoptera except butterflies are all called moth. Places that have many butterflies are South America, Africa, Southeast Asia.

- Moth

General term for Insect class Lepidoptera excluding butterflies. Body constructure basically is same to butterfly and generally has 2 pairs of membrane wings. Body and parts of appendage are covered with scales. Big jar is almost degenerated or disappeared, and mouths makes long absorbing vessel(spinned like spring when not used) by small jars which are unified from opposite sides

- Precambrian Times

Stromatolite Stromatolite, which originates from meaning of stone carpet in Greek, is a structure of accumalation made by Cyanobacterium, a life on earth. Cyanobacterium has made very important turning point on evolution of life.

- Disappeared creatures

Ediacaran Fauna These fossil creatures are oldest known multicellular organisms. As they did not have hard surface, they only have pressed trace, so we could not know the inside structure.

- Lower Paleozoic

Explosive appearance of creatures As it became Cambrian times, by highly increased sea area, hard-shelled sea animals explosively increased. By Ordovician period, almost every ancestors of nowadays invertebrates appeared.

- Middle Paleozoic

Many Cambrian fossils that are found in Yoho national park bergess pass of Canada Westside Rocky mountains are very important in understanding sea animals at that time. Its black close shale layer have fossils of non-shelled animals that are hard to be fossiled, apart from hard-shelled animal fossils.

- Upper Paleozoic

Landing of plants By Devonian Period, after first vascular plant appeared, filices, old tree, gymnosperm, primitive amphibia, insect without wings prospered on lowland swamps.

- Era of Dinosaurs

Reptiles that have appeared on end of Palezoic era prospered on land and sea during Mesozoic, and dinosaurs which have evolved from reptiles ruled the ecosystem of the earth till end of Mesozoic.

- Era of reptiles

By becoming Jurassic period, dinosaurs have been increased very much, sea reptiles prospered in sea and sky. Angiosperms and small mammals appeared on warm Cretaceous period.

- Dinosaur

Dinosauria are land reptiles that have lived during Mesozoic. Dinosaurs had sclaes on surfaces, and as they laid eggs, they are classified as reptiles. Dinosaurs differ from banded-leg reptiles such as lizard, crocodile, turtle, in that it has straight legs right under the body.

- Dinosaur fossils

Psittacoaurus
Lived : Early Cretaceous
Found : Mongol, China, Taiwan
Features : Most primitive horned dinosaur. As it has beak like parrot, it is also called parrot lizard.
Found first in Mongol, it was small and ornithischian that walked on two feet.

- Dinosaur Tracks

Place of origin: Kyungsangbukdo Eauseong
Tracks of grass-eating dinosaur in the latter cretaceous period

- Tracks of Theropoda

Place of origin: Kyungsangnamdo Goseong Tracks of carnivorous dinosaur in the latter cretaceous period

- Allosaurus

Allosaurus is the fiercest carnivorous dinosaur and ancestor of Tyrannosaurus in the cretaceous period. The length of body is about 12m and weight is 3t.

- Dendrolite

Tree trunk buried in the geographical age

- The period of Mammalia I

Mammalia evolved rapidly after the Cenozoic era and angiosperms are diversified. Human appeared from Primates evolved from primitive insectivora and evolved into Homo sapiens.

- The period of Mammalia II

Mammalia start to evolve rapidly after dinosaur disappeared 65million years ago. Primates are evolved separately from Old World Monkeys in the former Miocene.
-Mammoth < Eleophas primigenius >
Mammoth lived in the middle of diluvial epoch to Ice age. It is 3m big and molar tooth are thick and spiraled. They lived in cold region and died out at the end of diluvial epoch.

- Primates

It is special features that Primates are easy to vary.

- Internal structure of the earth

It is consisted of the earth's crust - 30~40§° from the surface of the earth-, mantle - 2,900§° from the earth's crust- and nucleus - center of the earth-.

- Structure of the earth's crust

The earth's crust is upper part of Mohorovicic discontinuity. It is consist of light rock including aluminum and magnesium.

- Structure of mantle and nucleus

The part of 2,900§° from the earth's crust is mantle. Density of Material that form mantle is high. Nucleus is 3,500§° from the beneath of mantle. 5,100§° from the beneath of mantle is called out core and that is liquid. The part from out core to the center of the earth is inner core.

- The earth and the surroundings

¡¤ Troposphere
   14§° from the surface of earth.
  You can watch weather phenomena like rain or clouds.

¡¤ Stratosphere
  About 50§° from the outside of troposphere.
  There is ozone layer under the stratosphere.

¡¤ Mesosphere
  50§° from the stratosphere.
  Mesosphere do an important role of energy movement.

¡¤ Thermosphere
  800§° from the mesosphere. We call it thermosphere or ionosphere.
  Ionosphere reflect radio waves to earth.

¡¤ Exosphere
  The upper air of thermosphere. Exosphere is influenced by the magnetic field
  of the earth. So it is called magnetosphere.

- Minerals

Minerals are solid which have regular chemical elements and physical properties. It is composed of mineral silicate.

- Mineral Classification

Glacial chemical classification is the most popular. Sapphire, Amethyst, Rock crystal, Calcite, Rose quartz, Rhodonite and Stalactite are exhibited.
