Hlais ntses squid (Sepioteuthis lessoniana) los yog oval squid nyob rau hauv chav kawm ntawm cephalopods, ib hom molluscs.
Kev faib khoom ntawm cuttlefish squid
Tus nqaj uas tsis tuaj yeem txiav pom yog nyob hauv Indo-West Pacific. Cov neeg nyob hauv thaj chaw dej hiav txwv ntawm dej hiav txwv Indian nyob hauv thaj av Hiav Txwv Liab. Cov dej nyob qaum teb ntawm Australia, New Zealand. Tus ntses nqaj nqaj kuj hloov pauv mus deb rau sab qaum teb ntawm lub hiav txwv Mediterranean thiab tseem tshwm nyob ze rau Islands Hawaii.
Chaw nyob ntawm cuttlefish squid
Hlais ntses squid nyob rau hauv cov dej hiav txwv sov sov nrog sov li ntawm 16 ° C txog 34 ° C. Lawv feem ntau tawm thaum hmo ntuj, thaum lawv ua luam dej hauv qhov dej ntiav txij li 0 txog 100 m sib sib zog nqus ntawm cov pob zeb dej rov qab, tsaj tsaws algae lossis raws cov ntug hiav txwv muaj pob zeb. Lawv sawv saum npoo dej thaum hmo ntuj, lub sijhawm no tsis tshua muaj txoj hmoo yuav los ntawm cov tsiaj nrhiav tua. Nruab hnub, raws li txoj cai, lawv tau txav mus rau hauv cov dej tob lossis khaws ntawm cov snags, reefs, pob zeb thiab algae.
Cov phiaj xwm sab nraud ntawm cuttlefish squid
Cuttlefish squids muaj lub ntxaiv-zoo li lub cev, yam ntxwv ntawm cephalopods. Qhov loj ntawm lub cev yog nyob rau hauv lub mantle. Sab nraub qaum tau tsim cov leeg. Nyob rau hauv lub mantle yog qhov tseem ntawm qhov tsim, uas yog hu ua - internal gladis (lossis "feather"). Qhov tshwj xeeb txawv yog "cov khau khiab loj", outgrowths ntawm sab qaum ntawm mantle. Cov fins khiav raws mantle thiab muab cov squid lawv cov yam ntxwv oval tsos. Qhov ntev tshaj plaws ntawm lub mantle hauv Cov txiv neej yog 422 hli thiab 382 hli hauv poj niam. Cov laus txiav ntses squid coj hnyav li 1 phaus mus rau 5 phaus. Lub taub hau muaj lub paj hlwb, qhov muag, kaus ncauj, thiab qog kua qog. Daim npog tawm muaj qhov muag sib txuas. Lub tsev pheebsuab raug xuas phom nrog serrated xuas khob rau kev tswj hwm tus neeg raug tsim txom. Nruab nrab ntawm lub taub hau thiab lub mantle muaj lub funnel los ntawm kev uas dej hla thaum lub cephalopod txav. Kab mob hauv nruab nrog cev - gills. Lub kaw lus circulatory raug kaw. Cov pa oxygen nqa cov protein hemocyanin, tsis yog hemoglobin, uas muaj tooj liab ions, yog li xim ntshav yog xiav.
Squid cov tawv nqaij muaj cov xim xim hu ua chromatophores, uas hloov xim lub cev sai raws li tej yam kev mob, thiab muaj cov kua mem uas tso tawm cov huab tsaus ntawm kua los ua rau cov tsiaj ua tsis taus.
Luam yug ntses ntawm ntses squid
Thaum lub caij ua kev nteg qe, cov nqaj ntses squid sib sau ua ke ntawm qhov ntiav. Nyob rau lub sijhawm no, lawv txo qhov kev hnyav ntawm lub cev xim thiab txhim kho cov xim ntawm lawv caj ces. Cov txiv neej ua qauv zoo li “striped” lossis “shimmer”, lawv dhau los ua lub cev thiab ua haujlwm. Qee tus txiv neej hloov lub cev xim kom zoo li poj niam nyiam thiab mus ze poj niam.
Cuttlefish squid tso lawv cov qe txhua xyoo puag ncig, thiab lub sijhawm sijhawm ntawm kev tso qe yog nyob ntawm qhov chaw nyob. Cov maum ntses nteg qe ntawm 20 txog 180 qe, ua rau hauv cov tsiav tshuaj uas ntuag, uas tau pw hauv ib txoj kab ncaj ncaj rau ntawm pob zeb, corals, nroj tsuag raws ntug hiav txwv. Sai li tus poj niam lays qe, nws tuag. Cov qe yuav tsim kho hauv 15 mus rau 22 hnub nyob ntawm kev ntsuas kub. Cov zawv me me yog 4.5 rau 6,5 mm ntev.
Cwj pwm ntawm kev muab ntses nqaj nqaj
Cuttlefish squid sawv ntawm qhov tob mus rau hauv qhov dej ntiav thaum hmo ntuj kom pub plankton thiab ntses. Cov tub ntxhais hluas, raws li txoj cai, tsim pab pawg. Lawv qee zaum qhia pom kev ua noj ua haus. Cov laus tawm tsawv yos hav zoov ib leeg. Hlais ntses squid siv hloov lub cev xim sai los qhia rau lawv cov neeg txheeb ze ntawm cov kev hem thawj, cov khoom noj muaj txiaj ntsig thiab qhia lawv cov thawj coj.
Noj cuttlefish squid
Cuttlefish squids yog nruj me ntsis carnivorous. Lawv pub tsiaj rau plhaub thiab ntses, tab sis kuj noj cov kab, zooplankton, thiab lwm yam tsiaj nyob hauv hiav txwv.
Cov ntsiab lus rau ib tug neeg
Cuttlefish squids tau ua tiav. Lawv siv tsis tas rau khoom noj, tab sis kuj yog kab nuv ntses rau kev nuv ntses. Hlais ntses squid yog ib qho tseem ceeb ntawm kev tshawb fawb txog kev tshawb fawb raws li lawv muaj kev loj hlob sai, lub neej luv, muaj cov xwm txheej qis, tsis pom kev noj tsiaj, yug tsiaj hauv dej thiab yooj yim los soj ntsuam hauv chaw kuaj. Giant axons (cov txheej txheem hlab ntsha) ntawm squid siv nyob rau hauv kev tshawb fawb hauv neurology thiab physiology.
Kev txuag cov xwm txheej ntawm cuttlefish squid
Cuttlefish tsis muaj kev hem thawj. Lawv muaj cov naj npawb ruaj khov thiab faib dav dav, yog li lawv tsis muaj kev hem thawj nrog rhuav tshem yav tom ntej.
