Inja ye-pike yolwandle (uNeoclinus blanchardi) ingeyomndeni wakwaChenopsia, i-oda lePerciformes. Isici esiyinhloko umgodi omkhulu womlomo, owehlukanisa nezinye izinhlobo zezinhlanzi.
Ukusatshalaliswa kwezinja zasolwandle.
Inja yePike ingatholakala eduze nezindawo ezivulekile zolwandle lwasePacific. Lezi zinhlobo zisakazeka zisuka eSan Francisco eningizimu ziye eCedros Island. Itholakala emanzini esifundazwe saseCalifornia naseMexico.
Indawo yokuhlala yenja yolwandle.
Izinja zama-pike zihlala ezingxenyeni ezingezansi zasolwandle zesifunda esishisayo. Zimboza ukujula okusukela kumamitha amathathu kuya kwamashumi ayisikhombisa nantathu. Ngezinye izikhathi, bahlangabezana nogu oluvulekile esihlabathini noma ngaphansi kodaka ngaphansi kwegagasi eliphansi. Njengomthetho, izinhlanzi zihlala emagobolondweni angenalutho e-clam, emigodini elahliwe, imifantu emadwaleni angaphansi kwamanzi nasemifantwini. Kwezinye izindawo bahlala ngisho nasezitsheni ezilahliwe ngemuva kokusetshenziswa. Cishe wonke amabhodlela kabhiya alahlwe eSanta Monica Bay ayindawo yokugcina izinja zepiki.
Lo doti uyindawo ephephile lapho izinhlanzi zizizwa ziphephile.
Kungakhathalekile ukuthi hlobo luni lokukhosela, izinja zasolwandle ezisolwandle zakha indawo yokuhlala njengekhaya labo futhi zivikela ngokuqinile insimu kubantu abangenayo. Lapho indawo yokukhosela iba nkulu, izinhlanzi ziyanda.
Izimpawu zangaphandle zenja ye-pike yolwandle.
Inja ye-pike iyona enkulu kunazo zonke kuwo wonke ama-fringeheads. Kungaba ngamasentimitha angama-30 ubude.Umzimba mude, mncane futhi ucindezelwe. Izici eziyinhloko zomehluko yi-dorsal fin ende ne-wavy "bang-appendage" ekhanda. Ukuvulwa komlomo omkhulu kuhlaba umxhwele ikakhulukazi. Yakhiwa yisici somhlathi omude ophezulu, onemikhawulo efinyelela emaphethelweni e-operculum. Imihlathi inamazinyo amaningi afana nezinaliti. Ubukhulu bomlomo bukhulu kwabesilisa kunabesifazane. Umphetho omude we-dorsal ugijima usuka ku-occiput uye kufini eyindilinga ye-caudal. Isiphetho se-anal sisuka ekuvulekeni okungaphandle kuye ekugcineni kwesiphetho se-caudal.
Ikhanda likhulu ngokumangazayo, ukuphela kwangaphakathi kuyindilinga ngezindebe ezivelayo. Umbala wenja ye-pike yolwandle imvamisa iba nsundu noma mpunga ngezindawo ezahlukahlukene zombala obomvu noma oluhlaza okotshani. Cishe kunabesilisa abamnyama abanemihlathi emikhulu edwetshiwe ngombala ophuzi ngokugqamile ngemuva. Kunezindawo eziphaphathekile ezinhlangothini zekhanda. Kuhlukaniswa ama-ocelli amabili ezinhlokweni zomgogodla we-dorsal, owodwa ophakathi kwezimpande zokuqala nezesibili, bese owesibili uqhubeka kancane. Lezi zindawo zinombala oluhlaza okwesibhakabhaka futhi zinomngcele ophuzi.
Ukukhiqizwa kabusha kwenja yolwandle.
Izimpawu zokubekwa kwezinja zivame ukuqala ngoJanuwari kuya ku-Agasti. Insikazi ibeka amaqanda emgodini oshiywe phansi noma ngaphansi kwamatshe. Amaqanda mancane, ngosayizi ongu-0.9 kuye ku-1.5 mm. Iqanda ngalinye libukeka njenge-globule kawoyela futhi linamathele esidlekeni nakwamanye amaqanda anemicu ekhethekile. Eyesifazane eyodwa izala amaqanda angaba ngu-3000, bese kuthi awesilisa aqaphe iklatshi. Izibungu zivela cishe ngo-3.0 mm ubude. Izinja zama-pike zihlala endaweni yasolwandle cishe iminyaka eyi-6.
Ukuziphatha kwenja yolwandle.
Izinja zepike ziyizinhlanzi ezinolaka ezivikela izindawo zazo zokuhlala ezitheni ezihlaselayo, kungakhathalekile ubukhulu bazo. Isikhathi esiningi basuke bephumule, kukhombisa amakhanda abo kuphela ngaphandle kwekhava.
Lapho ezinye izinhlanzi zihlasela indawo ehlala kuyo, zihambisa izembozo ze-gill emaceleni, zivule umlomo wazo omkhulu futhi ziveze amazinyo amise okwenaliti.
Ekuqaleni, izinja ezixubene zixwayisa isitha ngokuhambisa imihlathi yazo. Uma isigelekeqe sibhukuda eduze nendawo yokukhosela, inja ye-pike ngokushesha ibhukuda iphume endaweni yokukhosela bese ivikela insimu.
Lapho kuvela izinhlobo zezinhlobo zazo, izinhlanzi zivula imilomo yazo ngokuqinile bese zisondelana. Ngasikhathi sinye, banquma ukuthi ngubani kubo onamandla, futhi ongafuna insimu ehlala abantu. Uma i-pose esongelayo ingesabisi isitha, khona-ke ukuhlaselwa kuyalandela futhi kusetshenziswa amazinyo abukhali. Izinhlanzi ezinolaka zihlasela cishe zonke izinto (kufaka phakathi abatshuzi) ezivela ebangeni elibonakalayo. Le nhlanzi encane edla lubi ihlala ishiya ithuba elihle lokufaka izinaliti ezicijile esitheni, futhi, ithukuthele ngenxa yokungena okungadingeki komzingeli, ayidedeli inyamazane isikhathi eside. Abatshuzi be-Scuba bavame ukubika amasudi alimele ngenxa yokuhlaselwa okuvela kulezi zinhlanzi ezincane ezinolaka. Kodwa-ke, ngaphandle kokuhlaselwa okungajwayelekile kwabantu okudala ukuhlaselwa, izinja zepike zibhekwa njengezinhlanzi ezingenabungozi. Ngokuthakazelisayo, ngale ndlela, izinja zasolwandle nazo zivikela amaqanda abekiwe.
Ukunyakaza kokubhukuda ezinjeni ze-pike kuyinkimbinkimbi impela. Isenzo se-dorsal and anal fin senza ikhonsathi namaphiko we-pectoral nomsila ngesikhathi sokuhamba phambili. Izinja zepiki zibhukuda ngokushesha futhi ngokushesha, zihamba ngokungahleliwe emabangeni amafushane, ziguquka njalo. Ukubhukuda okuzolile okude akujwayelekile kulezi zinhlobo zezinhlanzi. Esikhundleni sokubhukuda kuqala emgodini, izinja ezi-pike ziyabhukuda zingene nomsila wazo phambili ukuze zingaphenduki.
Ukudla kwenja yolwandle.
Inja ye-pike yolwandle iyisilwane esidla ezinye. Udla isisindo sokudla ngesisindo esiphindwe ka-13.6 kunesisindo somzimba sezinhlanzi. Lomzingeli ocathamayo ugxuma aphume endaweni yakhe yokukhosela ukuze abambe inyamazane yakhe futhi abambe isisulu esishelelayo esinezinyosi ezicijile - amazinyo.
Yiziphi izidalwa izinja zasolwandle ezikhetha ukuzidla endle azaziwa. Izinhlobo zezinhlanzi ezisondelene kakhulu, ezinjengenja ye-tubeblennies ne-flagblennies blend, zaziwa ngokudla kakhulu ama-crustaceans.
Isimo sokongiwa kwenja yasolwandle.
I-seal pike ayifakiwe kuhlu olubomvu lwe-IUCN. Lolu hlobo alunazo izinsongo, ngaphandle kwethonya lokungcola kogu. Yize izinhlanzi zalolu sayizi zingaba isisulu sezilwane ezinkulu ezidla ezinye, ikhono lamanzi kasawoti lokuzivikela kungenzeka linciphise le ngozi.
