綽號海中之王（the king of the sea）的腔棘魚，最近引起了許多生物學家投入探討。一開始科學家以為牠們已經滅絕了；後來一個科學家在南非發現了一個樣本，但並沒有保存下來；陸陸續續的有人發現腔棘魚並作成標本；直到最近一群科學家在科摩洛島外海裡發現兩隻腔棘魚，但科學家認為那兩隻不是主要魚群，但還是很高興有了如此重要的發現。

In nickname sea king (the king of the sea) the cavity stickleback, recently caused many biologists to invest the discussion.As soon as starts the scientist to think they already extinguished ; Afterwards a scientist has discovered a sample in South Africa, but certainly has not preserved; The one after another some people discovered the cavity stickleback and makes the specimen; Until recently group of scientists touches in the Luo river island open sea in the branch to discover two cavities sticklebacks, but the scientist thought that two are not the main fish groups, but was very happily had the so important discovery.
Famous activation rockfish; Since the cavity stickleback all was continuously considered is animal which only has in the fossil, it in Devonian period to Jurassic Period (three hundred million seven surely years ago to hundred million five surely years ago) this period of time are very common, but was considered when cretaceous period extinguished the light. When 1939, a scientist has discovered a sample in the South African seacoast, but he has not certainly preserved the fish, the fish finally decomposes. The scientist certainly did not know that, frequently attains in the branch not Luo river this place fisherman in theirs fishing discovers the cavity stickleback. Because this parent fish cannot eat does not have the value, the fisherman catches this parent fish all is discards it. On the island inhabitant brings excitedly regarding the cavity stickleback is aloof, but very happy this kind of they are called Kombessa the fish turns the precious fish.
Why does the cavity stickleback such receive everybody the attention, my understanding, classifies to the following several points:
。The most famous fish live fossil, was considered as early as should extinguish in seven surely years ago biology, afterwards has unexpectedly discovered the living specimen.
。Possibly is the fish nearly turns into an amphibious kind of among important link, hunts for the dragon like China possibly is the dinosaur evolves in the birds, a count for much link like that.
。Although has already discovered the survival cavity stickleback, but the quantity is short to quickly turned the real fossil.
。The cavity stickleback's is not surely big with seven years ago change, is how condition let the cavity stickleback have the original story the fish which could adapt to circumstances or environment with other to survive together down.
Annotate: The Comoro archipelago sea, is leaving the shore 100 meters place, some many places water depth surpasses 1,000 meters, but is approaching the seacoast sunlight the sufficient place, some piece narrow but very developed coral reef (裙礁). Downward looked from the coral reef edge that, may see the lava black rock, with the steep slope which forms by the dark color sand, a nature extends the deep sea, the lava rock everywhere forms in the water the cavern. In a deeper seabed, everywhere obviously the monotonous rock and has the ripple the sand slope gradually to hide, and in coelenterate's whip 海柳 coral and black fish. From the water depth 200 to 500 meter neighbor, the fish which catches has 鯖 the hairtail and the wild rose belt 鰆 and so on. These live together with the cavity stickleback in the deep sea fish, all some pair also sees the big eye under the weak light which sees, gathers incisive dentition which as soon as bites does not put; In the pitch-dark sea, these fish may 胼 and the cavity stickleback compete to struggle the food.
The habitual cavity stickleback is the travelling by night cavity stickleback daytime hides in a water depth 170~230 meter cavern static is motionless, after the sunset, swims in twos and threes toward the deep place migration, the capture game. The cavity stickleback is closely nips the game with his/her incisive tooth, then a tone swallows down, they only can catch arrive the oral area dead ahead game, this is the reflective behavior. Like saves the energy only to rely on the probability like this which the fortuitous hunting way succeeds very few, therefore the attack essential both agile and is accurate, therefore its forehead 先端 lips function sensation game when swimming sends out the weak electric field, then the determination game's position cavity stickleback is being reduced year by year The cavity stickleback's alight, scientist's publication lets it become famous overnight, the cavity stickleback is limited, but humanity's ambition is infinite, the over-trapping and the nonchalant injury, cause the number extremely quick reduction. Saves in these deep seas the live fossil, needs a huge funds, the world each place scientist, is raising, we hoped for this day will be able soon to arrive. The ant because the body is small, cannot break through the water the surface tension, therefore may float very long period of time in the water surface front, completely loses to the body 溼 passes cannot sink, if is the sole ant mostly is because water flowing brings it to the isolation on the water object, but big group ant so long as sacrifices the partial ants, also may use the ant sea tactic to put up the ant body bateau-bridge the destination which arrives through the water surface wants. Rains, the worker ants can revolve to form spherically, is called "ant ball", 蟻后 will encircle in central protects, and matter and so on secretion fat will let the ant ball not be able to shatter by the water, the ant ball when 水勢 slightly will draw back, has the land will be allowed to anchor may rapidly turn the troop, will let the worker ant 蟻后 tow nips comes ashore. Ant's body is by the forehead, the chest and the abdomen constitutes; The forehead has the mouth apparatus and the antenna. The abdomen can secrete one kind of subpoena 費洛 Mongolia, good enabled the afterwards partner to smell this kind of secretion the smell, followed the way advance. Is uses for as for the antenna to transmit each other the news; Generally speaking, they all have the duplicate eye, only is some not very is certainly big; But also somewhat does not have the duplicate eye. Ant's chest has six feet, the first foot clean antenna antenna combs, the function and the brush, the comb are same. Among chest and abdomen, some small abdomen handle, this is ant's characteristic. The ant is similar to gathers in groups at the small branch's ophid, or is same in the rice paddy locust army; Obviously inside the animal has very many moves in groups. But they not necessarily only have the dependent association to be able to live. But, the ant has been different, if only separates their, is does not have the means survival, their each other assignment food, the abdomen sends out 費洛 Mongolia's smell, the antenna mutually bumps touches the transmission information, these all are has had for the orderly group life. Therefore converges them the social insect. Besides ant, but also has the honeybee and the termite, also is the social life. The ant take the nest as the life center, the majority ant all builds the nest in the earth, but also some types are live in the place dry branch, or builds the nest in the bough. Moreover, because ant's type very many, therefore its feeding habits very are also complex, they have take the animalism or the vegetative quality as the staple food; Even, in the South America, some leaf-cutters, can transplant the mushroom class like the farmer to be same, to the fungus takes their food! Because the ant group has the certain life and food, for avoids mutually between capture, they can divide as far as possible come the housing. The ant has 蟻后, the aner, the worker ant division of, their each other acting different role, if the worker ant has name of the soldier ant, the duty department defense duty. The life is year or two years. The aner can in the reproduction season, after 蟻后 交尾 soon be the death. But 蟻后 actually may exactly ten years, it every year be possible to produce many eggs, therefore so long as has 蟻后, ant's lair can be continuous the unceasing reproduction.
