Njengoba nje kukhona ama-crayfish, kukhona ne- izinkalankala zolwandle. Lezi zinkalankala yizinkanyezi zalesi sihloko. Kunezinhlobo ezingaba ngu-4000 XNUMX esingazibiza ngokuthi izinkalankala kanti eziningi zazo zihlala olwandle. Lezi zinkalankala zinezici ezihlukile kulezo ezihlala emfuleni ngoba kufanele zivumelane nolunye uhlobo lwendawo.
Kulesi sihloko sizokutshela konke odinga ukukwazi ngezinkalankala zasolwandle.
Izici eziyinhloko
Noma ngabe zivela ohlakeni lomfula, izinkalankala zingaphansi kokuhleleka kwama-decapods. Lokhu kusho ukuthi aqukethe amapheya amahlanu emilenze. Ngakolunye uhlangothi, sinemilenze efakwe esiswini sayo eye yavela kuwo wonke umlando. ukuze ube yizindlwana noma impintshisi. Ngakolunye uhlangothi sinemilenze esele yemoto.
Inkalankala yasolwandle inezici ezahlukahlukene ezithile ngokuya ngohlobo lwenhlobo, njengokukwazi ukushintsha ubukhulu namandla ayo maqondana nosayizi wezinzipho zayo. Umsebenzi oyinhloko we-tweezers ukuthatha, ukusika nokusebenzisa ukudla kwakho. Bayayisebenzisa futhi ukuzivikela kulabo abangaba yizisulu zokwenza okuthile futhi nokwenza imicikilisho ethile yokuqoma kulabo abashadayo.
Bajwayele ukuba nemikhuba ye-benthic, okusho ukuthi, zulazula phansi kolwandle lapho bondla khona, badle futhi bazale khona. Ezinye zalezi zinhlobo zenze enye imodeli yempilo uqobo futhi zithanda ukuchitha isikhathi ekujuleni okuthe xaxa. Esinye isici izinkalankala zolwandle ezigqamayo ukuthi zivame ukushintsha kancane kuye ngohlobo lwazo. Sinesibonelo esicacile se- inkalankala. Lapho zihlangana amasonto athile, zibheka ngasogwini bese zishintsha isihlangu sazo ukuzivumelanisa nosayizi omusha.
Inkalankala yolwandle ingakwazi ukuzivumelanisa nempilo esemhlabeni uma nje ihlala eduze nolwandle. Abavame ukubhukuda kahle kepha basebenzisa imilenze yabo ukuhamba nokuhamba phansi olwandle. Lokhu kubizwa ngokuba nemikhuba ye-benthic. Kunezinhlobo ezithile zezinkalankala zasolwandle ezifana ne- inkalankala kakhukhunathi ukuthi ayikwazi ukuhamba nje kuphela, kodwa futhi nokuqwala izihlahla zesundu ukuthola ukudla kwayo. Lokhu kubenza babe namandla amakhulu okuzivumelanisa nezimo ezintsha futhi bakwazi ukusinda kahle.
Ukudla kwenkalankala yasolwandle
Zonke izinhlobo zenkalankala zinazo ngokwemvelo ukudla okunomsoco ngokuphelele. Lokho wukuthi, bayakwazi ukusebenzisa noma yiluphi uhlobo lwezinto eziphilayo, kungaba yisilwane noma imifino. Ukondla banezibopho ezinamandla futhi yizo ezibasiza ukuba bakwazi ukubamba futhi baphathe ukudla kwabo. Lezi mpintshisi zibukhali impela. Uma inkalankala iba nkulu, izikhonkwane zayo ziba namandla amakhulu futhi zibe nkulu. Ngaphezu kwalokho, bayakwazi ukusebenzisa amandla amakhulu kakhulu njengoba izihlungi ziba nkulu.
Ngama-tweezers asetshenziselwa ukusika nokufaka isihloko njengezinhlanzi ezincane, amanye ama-crustaceans, izidalwa ezincane kanye ne-algae. Ukuze wazi kahle ukuthi izinkalankala zidla ini, kuyadingeka ukwazi ukuthi iningi lalezi zilwane zingosomathuba. Yize nazo zibonakala zibe nsundu ekudleni kwazo, zidla ezinye izidalwa ezifa noma zimane zibe ngabahlambalazi. Ukuzingela ukudla kwakho noma ukudla kungahlala kunzima futhi kube yingozi. Izinkalankala zikwazi kahle lokhu futhi zikhawulelwe ekubeni yizilwane ezingosomathuba.
Kwesinye isikhathi, ungathola lezi zilwane ogwini lolwandle zifuna ngisho nendle yabantu. Kukhona ezinye izinkalankala ze-marquis nazo ezondla ngokuhlunga, okungukuthi, ukuthatha izakhi zomzimba ndawonye nenhlabathi namanzi, zilahle lokho ezingakudingi.
Indawo nendawo okusatshalaliswa kuyo
Lezi zinkalankala zitholakala cishe kuwo wonke umhlaba. Alukho ulwandle emhlabeni wonke olungenalo okungenani uhlobo olulodwa lwenkalankala yolwandle. Yize bengahlali isikhathi eside endaweni eyodwa kwazise bavame ukufuduka, kuzo zonke izilwandle zomhlaba ungabona izinkalankala.
Bayakwazi ukuzivumelanisa cishe nanoma yiluphi uhlobo lwendawo yokuhlala inqobo nje uma behlangabezana nazo zonke izidingo zayo. Njengoba indlela abadla ngayo ihambisana nezimo eziningi, abadingi izimo eziningi kakhulu zemvelo ezithandekayo kubo. Uma izimo zamukeleka ngokulingene, into ejwayelekile kunazo zonke ukuthi inkalankala yolwandle iyazivumelanisa kalula.
Ungabathola kuze kube ngamakhilomitha amahlanu ukusuka ogwini lolwandle inqobo nje uma benesikhungo abazobuyela kuso. Benza lokhu ukuze bathole ukudla ngendlela ephumelela kakhudlwana. Kulezi zindawo Ziphila ngokudla izikelemu ezincane, ama-crustaceans, ama-algae debris kanye nanoma yini engatholakala emifantwini yamadwala. Lezi zindawo zivame ukufihlwa ukuze zihlale ziphephile ezilwaneni ezizingelayo.
Yize bekhona cishe yonke indawo emhlabeni, iningi labo litholakala e-Atlantic Ocean. Ngaphezu kwakho konke, singathola futhi indawo enkulu yokusatshalaliswa ezindaweni ezishisayo lapho izinga lokushisa kwamanzi libajabulisa khona kakhulu ngoba lithanda ukwanda kwezakhamzimba. Bazokwazi ukuhlala cishe kunoma iyiphi imvelo ebathandayo.
Izinsongo ze-crab yolwandle
Isikhathi sokuphila salezi zilwane kunzima ukusinquma ngoba sinezinhlobo ezibalelwa ku-4000. Kodwa-ke, isilinganiso esijwayelekile siphakathi kweminyaka emithathu nengu-3 ubudala. Lesi sikhathi sokuphila singaphansi kwezinguquko ezingenzeka kwinani lezilwane ezidla ezinye noma izinguquko zemvelo. Ngokuvamile zizingelwa futhi zidliwe yizilwane zasolwandle ezinjengezingwane, izimfudu zasolwandle, i-dogfish, oshaka, ama-otter, kanye nezinye izinkalankala ezinkulu.
Lapho kunokushoda kokudla bayakwazi ukudlelana. Lo mkhuba waziwa ngokuthi yi-cannibalism. Lapho bephumela olwandle futhi bangahlangabezana nezinsongo ezithile. Amaqanda noma izibungu zabo nazo zisengozini. Uma zisolwandle, izibungu zazo zingadliwa ezinye izilwane futhi uma zisemhlabeni, ngamakati nezinja ezidla kuzo.
Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi ngenkalankala yolwandle.
Uhlobo oluhle kanjani !!!
