Barnacles: yees duab, txoj kev ua neej

Feem ntau cov neeg uas tau nyob rau lub puam yog yuav them sai sai mus rau lub me me volcanic formations ntawm dawb xim. Lawv yuav tsum densely them nrog nqaum pob zeb thiab tawg tsam ntawm ntau yam underwater lug. Cov lug - zoo li ntawm ntau hom ntawm crustaceans.

hom

Niaj hnub no peb tham txog cov qog nqaij hlav Barnacles, thiab txawm raug xa mus rau raws li Barnacles. Subclass Crustaceans. Barnacles - Cov neeg sawv cev ntawm cov hauv qab no hom ntawm crustaceans:

• Thoracica - no muaj xws li Barnacles thiab Barnacles.
• Acrothoracica - me ntsis boring cov ntaub ntawv uas nyob hauv lub zoo li ntawm shellfish.
• Apoda - lwm yam tsiaj Thoracica ib tug neeg sawv cev ntawm cov pab pawg neeg.
• Rhizocephalans (Rhizocephala) - biofity decapod.

Barnacles, ntawm uas muaj txog 1200 hom nyob thoob plaws hauv lub ntiaj teb no thiab nyob rau hauv lub seas. Qhov loj tshaj pes tsawg tus ntawm ntau hom yuav muaj nyob rau hauv qab ntsev nqaum dej. Qhov ntev qog nqaij hlav pib nrog ib tug qhov siab ntawm 3 hli (hom Chthalamus) thiab cuag rau ib lub cheeb ntawm 70-100 hli thiab ib qhov siab ntawm 120-150 hli (lub genus Balanus nubilus).

Tej yam loj Barnacles khom tsuas yog nyob rau hauv cov pob zeb, submerged. Piv txwv li, qog nqaij hlav, nyob rau hauv lub Pacific Ntug dej hiav txwv ntawm lub tebchaws United States of America, yuav ncav cuag ib tug luj ntawm 1.5 kg.

Barnacles: txoj kev ua neej

Cov neeg - nyob ib leeg ntawm tag nrho nws cov txheeb ze, uas yog "tswm lub neej". Ib tug ntawm cov yam ntxwv tseem ceeb yog cov muaj peev xwm tsim barnacle nplaum tshwj xeeb tshuaj uas yuav pab lawv lo rau yuav luag txhua qhov chaw. Nws hardens sai heev nyob rau hauv ib tug ntub dej ib puag ncig thiab steadfastly nyob rau hauv cov huab kub thiab pressures. Barnacles nrees entwine pawg, pob zeb thiab lwm yam nyuaj chaw.

Barnacles txuas mus rau txhav khoom uas yog immersed nyob rau hauv dej, xws li cov bottoms ntawm ships nyob rau hauv chaw nres nkoj. Lawv yuav pom nyob rau hauv lub zoo li ntawm mollusks, zoo li ntawm crabs thiab whale daim tawv nqaij.

Heev raug rau saum huab cua, tsis muaj kub los yog cov dej tshiab yog teeb meem rau Barnacles, tab sis lawv cov conical zoo li tseem los mus tuav rawv lub xeem, kom txog rau thaum lawv hnav tawm. Thaum lub sij hawm reflux qog nqaij hlav nkaum nyob rau hauv multiplate plhaub, uas muaj calcium carbonate.

Barnacle kab yog ib feem ntawm lub plankton, thawj zaug link nyob rau hauv cov zaub mov saw. Barnacles yog heev muaj menyuam coob coob marine tsiaj. Nqa rau sab qaum teb-sab hnub poob ntug dej hiav txwv ntawm ces txoj kev tshawb no qhia hais tias cov crabs, uas nyob rau ntawm lub lais, ua txhua xyoo trillion kab.

Qav qog nqaij hlav pib nteg qe rau peb lub lim piam ntawm hnub nyoog thiab ua peb lub sij hawm ib xyoos txog 10 txhiab kab - thiab thiaj li thoob plaws nws lub neej (rau 4-5 xyoos).

Yug crustaceans ua luam dej tawm los ntawm lub zoo li ntawm cov niam txiv thiab yuav luag tam sim ntawd ua cov zaub mov ntawm plankton-noj cov tsiaj. Cov neeg uas muaj kev tswj los mus ciaj sia ib ob peb lub lis piam nrhiav tau ib tug tshiab qhov chaw ntawm qhov chaw nyob. Hauv rau hauv av, lawv pib paim ib tug nplaum substance. Ib ob peb teev tom qab, nws hardens, thiab muaj los qhov kawg transformation kab mus rau hauv ib tug neeg laus mob cancer.

B, muaj raws ntawm rau superimposed on txhua lwm yam calcareous tej nplaim 5-10 hnub cov tub ntxhais cancer kiag locks nws tus kheej mus rau hauv lub khob hliav qab.

uas tsis yog-cab Barnacles

Tsis-cab Barnacles raug muab faib ua ob lub ntsiab hom - Barnacles thiab Barnacles. Lawv lub cev shrouded nyob hauv ib lub mantle, uas allocates calcareous phaj nyob rau hauv lub dab ntxuav tes. crustacean lub cev yog muab faib mus rau hauv lub taub hau, qab plab thiab lub plab mog.

Nyob rau hauv lub taub hau yog nyob antennules (antennae), uas ua hauj lwm hauv feem ntau tus neeg mob kov. Antennae lub sab crustaceans kuj lub cev thiab lub zog.

Nyob rau lub hauv siab yog biramous rau officers ntawm lugs, los ntawm cov uas mob cancer sau dej nyob rau hauv lub mantle kab noj hniav nrog cov khoom noj seem - microorganisms. Tuav ob txhais ceg, mob cancer attracts plankton absorbs oxygen los ntawm cov dej.

Nyob rau hauv cov tsiaj, tsis muaj gills, thiab ib lub qhov muag yuav paub qhov txawv xwb lub teeb los ntawm qhov tsaus ntuj. Feem ntau ntawm Barnacles - hermaphrodites.

Nyob rau hauv cab Barnacles sacciform lub cev, tsis muaj lub dab ntxuav tes, hnyuv thiab nqua.

barnacle

Spanish, Italian thiab Greek ntug dej hiav txwv raws li ib yam txawv ntawm Barnacles - ib tug Barnacles. Lawv ua tsawg tsis xis nyob dua lawv lwm hom - Barnacles. Os yog txuas mus rau floating tej khoom xws li daim lwj ntoo. Thaum thawj zaug rau theem ntawm txoj kev loj hlob ntawm lub kab ntawm Barnacles thiab Barnacles yog tib hom ntawm cov hav zoov. Thaum ib tug lub sij hawm ntawm deposition, raws li lawv yog glued nyob rau hauv qhov chaw, tab sis muaj ib tug dog dig ntau dua txoj kev ywj pheej nyob rau hauv tu tub tu kiv thiab kev noj haus.

Ntxuav tau cov ships los ntawm Barnacles

Txij ancient sij hawm, Barnacles (duab uas yog hais hauv qab no) yog qhov teeb meem ntawm lab ntawm cov tswv ntawm ships.

Lawv tshem tawm los ntawm lub bottoms ntawm ships yog ib tug ntev thiab complex txheej txheem, nyob rau hauv uas lab ntawm cov nyiaj yog siv.

Cov sov dej ntawm cov hlab dilation tshwm sim los ntawm qhov rau lub hlis fouling ua tus tswv rau nkim roj 40% ntxiv rau cov preservation ntawm ib txwm tsav tsheb pace.

Tej ceev yuav txo tau ua rau ib co nqi ntxiv, xws li:

• tu ntawm lub nkoj qab;
• lub purchase ntawm ntxiv roj.

Warships yog cov feem ntau yooj yim rau tus yeeb ncuab nyob rau hauv cov ntaub ntawv ntawm Symptoms mus rau lub nkoj ntawm Barnacles. Lawv ua tub rog nkoj nyob rau hauv tus kwv, uas, vim lub distortion ntawm cov ncha, nws yuav yooj yim rau sonar pab kiag li lawm yog mloog.

Raws li kws txawj, tsuas yog nyob rau hauv lub tebchaws United States txhua xyoo siv lab ntawm cov nyiaj nyob rau hauv lub purification ntawm fouling ntawm lub bottoms ntawm ob pab neeg peg xeem thiab cov tub rog tsev hais plaub.

Cov kev tiv thaiv ntawm cov hlab ntsha ntawm lub hauv qab

Thaum cov neeg tau pib kawm dej hiav txwv thiab seas, lawv sim mus nrhiav ib tug uas tiv thaiv lub Symptoms ntawm Barnacles rau ib lub nkoj. Phoenicians sim siv cob. Greeks sim ciab thiab ib, tab sis tsis muaj txhais tau tias yog tsis pab kom txog rau thaum tooj liab pib siv tau rau lub txheej ntawm ntoo yees.

Txawm li cas los, niaj hnub loj ships tooj liab - ib tug heev kim khoom, yog li ntawd tam sim no siv cov xim tsev, uas muaj xws li tooj liab oxide.

Tom qab leaching ntawm cov xim tshuaj, nws cov ntaub ntawv ib tug tshuaj lom zaj duab xis uas tiv thaiv lub nkoj los ntawm cov kab ntawm marine tsiaj.

Ib tug ntawm qhov tseeb yog qhov barnacle kab (yees duab positioned saum toj no) nws yog txuas mus rau ib tug taw tes ntawm lub nkoj, tom qab txoj kev ua ib lub plhaub lawm. Nyob rau nruab nrab, cov xim muaj hlau tiv thaiv rau hauv qab ntawm lub nkoj tsis pub dhau peb lub xyoos.

Tus paub tsis meej ntawm lub nplaum

Txawm tias muaj tseeb hais tias Barnacles thab plaub swimmers thiab grieving tswv, lawv yog nyob rau hauv rau centuries attracted cov paj uas zaum. Charles Darwin siv ntau tshaj li yim xyoo ntawm nws lub neej kawm lawv.

Zaum ntseeg tau hais tias, yog tias koj kawm ib salient nplaum, nws yuav tau coj los ua ke ib tug zoo xws li cov nplaum cov khoom uas yuav tau ntse siv nyob rau hauv kev kho hniav, orthopedics, kev phais, traumatology, raws li zoo raws li nyob rau hauv kev lag luam.

Txawm li cas los, lub nplaum khoom yog nyob rau hauv tsis muaj hurry mus qhia lawv secrets. Nyob rau hauv lub khoom hauv lub xeev nws tsis tau yaj los ntawm muaj zog acids los yog organic solvents. Nws yog tsis raug tus ntawm cov kab mob thiab yuav mas kub saum toj no 200 ° C.

nthuav lus tseeb

Raws li paleontologists, Barnacles 400 lab xub tshwm sim xyoo dhau los. Txij li thaum Jurassic, lawv lub ntsiab attribute muaj lub siab tawv. Lawv seem, hais txog lub sij hawm qhia Barnacles tseem ruaj rau lub dav hlau uas lawv tsawm 150 lab lub xyoo dhau los.

Rau ib ntev lub sij hawm Barnacles kho mollusks, thiab tsuas yog ua tsaug rau cov lus qhib ntawm lub dawb-luam dej kab twb tau los mus txiav txim kev sib raug zoo mus rau lwm cov crustaceans.

Kev siv cov Barnacles nyob rau hauv cov zaub mov

Steamed cancer muaj ib tug saj ntawm roob ris thiab cw nyob rau tib lub sij hawm. Nws yog ua hauj lwm nrog ib tug tshwj xeeb ntses ua los ntawm nqaij ntses nyoo. Qhov no zaub mov yog menyuam los ntawm gourmets nyob ib ncig ntawm lub ntiaj teb no. Barnacles yuav noj nyoos zoo li raws li lawv tau kib los yog rhaub.

Cov no yog cov yooj yim thiab cim marine lub neej - Barnacles.
