Cyclops belongs rau tsev neeg ntawm copepods. Nkag mus rau hauv chav kawm ntawm crustaceans, cyclops muaj lub cev lub cev tshwj xeeb uas ua rau nws txawv ntawm lwm tus neeg sawv cev. Kuj ceeb tias, txawm tias lawv me me, cov crustaceans no tsis tsuas yog ua zaub mov rau cov ntses feem ntau, tab sis kuj tuaj yeem noj ntses nws tus kheej ua ntej nws muaj sij hawm loj hlob.

Kev piav qhia

Qhov tseeb, cyclops yog hais txog crustaceans, planktonic cov tib neeg uas tuaj yeem pom nyob hauv yuav luag txhua lub cev dej tshiab ntawm cov dej. Lawv yog cov zaub mov tseem ceeb rau feem ntau ntses thiab kib.

Tib lub sijhawm, lawv tus kheej noj ntau yam kab mob, kom cov dej huv si tas li. Tsis tas li ntawd, ua tsaug rau cov khoom noj ntawm Cyclopes, nws tau txais ib qho tseem ceeb ntawm kev qhia meej thiab kev txhim kho ntawm nws cov khoom zoo.

cov ntaub ntawv tseem ceeb

Feem ntau, txhua tus copepods hu ua cyclops vim lawv qhov zoo sib xws sab nraud, tab sis qhov no yog cov lus tsis tseeb, vim hais tias cov tsos ntawm txhua crustacean cyclops yog qhov txawv ntawm nws tus kheej. Cov neeg loj tshaj plaws, tsis tshua muajkev zam, tsis txhob tshaj 4.5 mm. Qhov nruab nrab, qhov loj ntawm tus neeg sawv cev yog los ntawm 0.5 mus rau 2 hli. Txhua Cyclops tuaj yeem muab faib ua cov txiv neej thiab poj niam raws li cov yam ntxwv ntawm kev sib deev. Cyclops yog crustaceans uas nws cov xim nyob ntawm cov khoom noj uas lawv noj, los ntawm qhov uas lawv noj ib feem ntawm cov xim xim, tab sis feem ntau lawv yog:

  • Grey.
  • Red.
  • Green.

Txawm tias lawv qhov loj me, Cyclopes feem ntau ua rau kev ua neej nyob. Nyob rau tib lub sijhawm, rau kev yos hav zoov, lawv feem ntau siv cov txheej txheem ntawm kev npaj txhij txog, dhia nrawm rau tus neeg raug tsim txom uas tsis xav txog. Thaum lub sij hawm thaum yos hav zoov tsis yooj yim sua vim li cas, lawv noj ntau yam algae.

Cyclops Appearance

Crustacean cyclops yog qhov muaj nyob hauv txhua xyoo nyob hauv cov dej. Yog li ntawd, lawv muaj kev cuam tshuam loj heev rau tib neeg lub neej, tsis yog tsuas yog nce cov pejxeem ntawm cov ntses, tab sis kuj kis rau tib neeg los ntawm nws nrog ntau yam kab mob cab. Qhov tseeb, daphnia, zoo li lub cyclops, yog crustaceans, cov qauv uas txawv heev los ntawm feem ntau ntawm cov neeg uas nyob rau hauv tib chav kawm ntawv nrog lawv, thiab uas muaj ib tug tshwj xeeb lub cev qauv, tab sis cov duab ntawm lub taub hau ntawm lub cyclops yog ntau. complex. Ntawm nws yog:

  • Ib lub qhov muag - nws yog nws tus uas ua lub luag haujlwm tseem ceeb rau qhov tseeb tias copepod tau txais nws lub npe thib ob - cyclops.
  • Ob khub kav hlau txais xov.
  • Lub ncauj apparatus.
  • ntau lub puab tsaig ceg.

Tib lub sijhawm, ib khub ntawm cov kav hlau txais xov raug tsimzoo dua thiab ntev npaum li cas rau lwm tus. Nws yog vim nws tias Cyclops txhim kho qhov xav tau ceev, tab sis nws kuj tuaj yeem siv rau lwm txoj haujlwm. Piv txwv li, ib tug txiv neej siv tau lawv los tuav ib tug poj niam thaum lub caij sib tw.

Tag nrho lub cev ntawm Cyclops muab faib ua ntu ntu, thaum lub hauv siab cheeb tsam tau txais tsib ntawm lawv ib zaug. Tsis tas li ntawd, cov ceg pectoral nrog cov bristles tshwj xeeb txuas rau nws, pab cov tib neeg ua luam dej. Lub plab tau txais 4 ntu thiab tshwj xeeb ceg thaum kawg.

Reproduction

Txhawm rau txiav txim siab txog poj niam txiv neej ntawm crustacean cyclops, nws tsuas yog txaus kom ntes tus neeg thiab saib nws los ntawm lub iav tsom iav. Yog tias koj pom ib lub hnab me me tom kawg ntawm lub cev, ces koj muaj ib tug poj niam nyob rau hauv pem hauv ntej ntawm koj, yog tsis yog txiv neej. Cov crustaceans no yug me nyuam ntawm tus nqi siab heev, vim hais tias lawv muaj peev xwm sai sai populate lub reservoir lawv tau nkag mus rau tsis ua hauj lwm. Ua tsaug rau qhov no, Cyclops muaj sia nyob zoo kawg nkaus hauv cov neeg coob txawm nyob hauv cov nkoj lossis cov thoob dej yug ntses npaj rau kev khaws cia.

Crustaceans, kev yug me nyuam uas ua tau hauv tsev thiab tsis yooj yim tshwj xeeb, raug ntes siv lub vas ua los ntawm cov ntaub nyias nyias. Hauv lwm qhov xwm txheej, nws yuav tsis tuaj yeem ntes cov crustacean me me no. Nws yuav yooj yim plam mus rau hauv lub qhov nrog rau cov dej ntws. Tom ntej no, koj yuav tsum tso ntau tus neeg mus rau hauv lub nkoj nrog dej.

Nauplius - qhov no yog lub npe ntawm tus menyuam mos uas Cyclops hatches. Crustaceans, kev yug me nyuam uas yog nqa tawm hauv cov khoom loj txaus, tau yug los ntawm lub hauv paus ntawm tus poj niam lub plab, hauv ib lossis ntau lub qe qe. Tag nrho tsim larvae tawm ntawm lub qe nteg rau yav tom ntej. Nws yog ib qho tsim nyog sau cia tias lawv qhov tsos yog qhov txawv ntawm ib tus neeg laus uas muaj kev txawj ntse.

Nyob rau hauv tej yam ntuj tso, nws yog ib qho nyuaj heev rau cov ntses mus ntes ib tug cyclops los yog nws larva vim yog heev txav. Yog li ntawd, ib yam yuav tsum tau coj mus rau hauv tus account. Yog tias cyclops crustaceans siv los pub cov ntses hauv tsev, ces nws tsim nyog ntuav cov tib neeg tsawg heev rau hauv lub thoob dej yug ntses, vim hais tias yog cov ntses tsis muaj sij hawm noj lawv raws sij hawm, cov crustaceans yuav pib loj hlob sai hauv thoob dej yug ntses thiab. yuav tsuas noj tag nrho cov kib.

Habitats

Feem ntau cov crustaceans Cyclops (Cyclops) thiab lawv cov txheeb ze ze Diaptomus (Diaptomus) tuaj yeem pom nyob rau hauv ntug dej hiav txwv ntawm pas dej thiab dej ntws. Ua tsaug rau lawv cov kav hlau txais xov muaj zog, lawv tshem tawm ob qho tib si los ntawm dej nws tus kheej thiab hauv qab thiab ua rau dhia lawv xav tau txav mus. Nyob rau tib lub sijhawm, qhov dhia nws tus kheej tuaj yeem ua rau txhua qhov kev taw qhia tsim nyog rau cyclops thiab tau ua dhau qhov deb txaus, muab lawv qhov me me.

Cyclops crustaceans tuaj yeem mus txog 75mm hauv ib pliag xwb. Rau kev sib piv: cyclops ua luam dej ntau dua 25 npaug sai dua li lub submarine ntawm qhov ceev nruab nrab.

Ib yam txawv ntawm crustaceansCalanus tuaj yeem pom txawm nyob hauv dej hiav txwv ntsev. Nws kuj yog ib feem tseem ceeb ntawm plankton thiab yog cov khoom noj uas yooj yim tshaj plaws rau ntau ntses.

Npaj qhov tseeb

Cov arthropods no tuaj yeem siv tau ua zaub mov muaj sia lossis khov rau cov ntses thoob dej yug ntses, muab cov khoom noj uas tsim nyog rau lawv. Nws yuav tsum raug coj mus rau hauv tus account tias chav kawm ntawm crustacean cyclops (Copepoda) suav nrog ntau tsev neeg.

Cyclops crustaceans zoo kawg nkaus hloov pauv hloov huab cua. Nyob rau hauv cov xwm txheej uas lub reservoir freezes los yog qhuav nyob rau hauv lub caij qhuav, lub cyclops secrete ib yam khoom tshwj xeeb thiab tag nrho envelop lawv lub cev nrog nws. Lub sijhawm no, lawv pom zoo ib yam li cocoon hauv lawv cov qauv, uas txhua yam tsim nyog rau lub neej tau khaws cia, txawm tias khov rau hauv dej khov. Muaj tsawg zaus, cyclops crustaceans khaws cov cocoon rau ntau xyoo, tab sis feem ntau tsis tas yuav muaj lub sijhawm ntev. Yog li ntawd, lawv tuaj yeem pom muaj ntau nyob rau hauv cov dej ntws ntawm cov daus yaj.

Lwm qhov tshwj xeeb ntawm cov crustaceans no yog kev tiv thaiv ib puag ncig, uas tsis zoo rau lwm yam tsiaj. Ua piv txwv, peb tuaj yeem hais txog ntau yam Cyclops li Cyclops strenuus, uas tuaj yeem nyob rau ib lub sijhawm txawm tias nyob hauv dej uas muaj hydrogen sulfide. Lwm hom kab mob tau txais txiaj ntsig zoo los ntawm gases, acids lossis lwm yam khoom tsis zoo rau lub neej ib txwm muaj.
