Galu wa pike (Neoclinus blanchardi) ndi wa banja la Chenopsia, dongosolo la Perciformes. Mbali yaikulu ndi malo akuluakulu amlomo, omwe amasiyanitsa ndi mitundu ina ya nsomba.

Kufalitsa agalu oyenda panyanja.

Galu wa Pike amatha kupezeka pafupi ndi malo otseguka a Pacific Coast. Mitunduyi imafalikira kuchokera ku San Francisco kumwera kupita ku Cedros Island. Amapezeka m'madzi a California ndi Mexico.

Malo okhalamo agalu oyenda panyanja.

Agalu a Pike amakhala pansi panyanja m'chigawo chapafupi. Amaphimba kuzama kwa mamita atatu mpaka makumi asanu ndi awiri mphambu atatu. NthaƔi zina, amakumana ndi gombe lotseguka pamchenga kapena pansi pamatope pansi pa mafunde otsika. Monga lamulo, nsomba zimatenga zipolopolo zopanda kanthu, mabowo osiyidwa, ming'alu m'miyala yam'madzi ndi ming'alu. M'malo ena, amakhala m'makontena omwe atayidwa akagwiritsidwa ntchito. Pafupifupi botolo lililonse la mowa lomwe limatayidwa ku Santa Monica Bay ndi malo opumira agalu.

Zinyalala izi ndi malo abwino oti nsomba zimve kukhala zotetezeka.

Mosasamala kanthu za malo ogona, agalu oyenda panyanja amakhazikitsa malo okhala ngati nyumba yawo ndipo amateteza mwamphamvu malowa kwa anthu obisalira. Kukula kwa malo ogona, ndi kukula kwa nsomba.

Zizindikiro zakunja kwa galu wanyanja.

Pike galu ndiye wamkulu kwambiri pamiyendo yonse. Chitha kutalika kwa 30 cm. Thupi ndi lalitali, lochepa komanso lopanikizika. Zinthu zazikulu zakusiyanaku ndizopindika zazitali zazitali komanso mutu wa "bang-appendage" pamutu. Kutsegula pakamwa kwakukulu kumakhala kochititsa chidwi kwambiri. Amapangidwa ndi nsagwada yayitali yayitali, yomwe malekezero ake amafikira m'mbali mwa operculum. Nsagwada zimakhala ndi mano ambiri ngati singano. Kukula kwa pakamwa kumakhala kwakukulu mwa amuna kuposa akazi. Chinsalu chachitali chotalikirapo chimayambira ku occiput mpaka kumapeto kwa caudal fin. Kumapeto kwa kumatako kumayambira kutsegulira koyambira mpaka kumapeto kwa kumapeto kwa caudal.

Mutu ndiwodabwitsa modabwitsa, kumapeto kwake kumakhala kozungulira ndi milomo yotuluka. Mtundu wa galu woyenda panyanja nthawi zambiri amakhala wofiirira kapena wotuwa ndimalo osiyanasiyana amtundu wofiyira kapena wobiriwira. Pali pafupifupi amuna akuda okhala ndi nsagwada zazikulu zojambulidwa wachikaso chowala kumbuyo. Pali mabala otumbululuka m'mbali mwa mutu. Ma ocelli awiri amadziwika pamisana ya dorsal fin, imodzi yomwe ili pakati pa mizu yoyamba ndi yachiwiri, ndipo yachiwiri pang'ono. Maderawa ndi achikuda buluu ndipo ali ndi malire achikaso.

Kuberekanso kwa galu wanyanja.

Sindikiza agalu a pike nthawi zambiri amabala kuyambira Januware mpaka Ogasiti. Mkazi amaikira mazira mumboza wosiyidwa kapena pansi pamiyala. Mazira ndi ochepa, 0,9 mpaka 1.5 millimeter kukula kwake. Dzira lirilonse limawoneka ngati globule la mafuta ndipo limamangiriridwa ku chisa ndi mazira ena okhala ndi ulusi wapadera. Mzimayi mmodzi amatulutsa mazira pafupifupi 3000, amuna amalonda ndodoyo. Mphutsi zimawoneka za 3.0 mm kutalika. Agalu a Pike amakhala m'malo am'madzi pafupifupi zaka 6.

Khalidwe la galu wokwera panyanja.

Agalu a Pike ndi nsomba zaukali zomwe zimateteza malo awo kwa adani, mosatengera kukula kwake. Nthawi zambiri amakhala akupuma, amangowonetsa mitu yawo osabisala.

Nsomba zina zikafika m'derali, zimasunthira zokutira m'mbali, zimatsegula pakamwa pake zazikulu ndikuwonetsa mano opangidwa ndi singano.

Poyamba, agalu ophatikizana amangochenjeza adani mwa kusuntha nsagwada zawo. Wobisalirayo atasambira pafupi ndi malowa, galu wachinyamatayo amasambira msasa ndikuteteza gawolo.

Anthu amtundu wawo akawonekera, nsombazo zimatsegula pakamwa pawo mwamphamvu ndikuyandikira. Nthawi yomweyo, amadziwa kuti ndi ndani wamphamvu kuposa iwo, ndipo amatha kutenga gawo lomwe akukhalamo. Ngati chiwopsezo sichikuwopseza mdani, ndiye kuti chiwonongeko chimatsatira ndikugwiritsa ntchito mano akuthwa. Nsomba zankhanza zitha kuukira pafupifupi zinthu zonse (kuphatikiza mitundu ina) zomwe zimawoneka patali. Nsomba yochepayi, yokonda kudya nthawi zonse imasiya mpata wabwino woponya singano zakuthwa m'daniyo, chifukwa chokwiyitsidwa ndi kulowerera kosafunikira kwa chilombo, sichisiya nyama kwa nthawi yayitali. Anthu ena osuta ma Scuba nthawi zambiri amafotokoza masuti owonongeka chifukwa cha ziwombankhanga zazing'onozi. Komabe, kupatula kuwukira kosavuta kwa anthu komwe kumayambitsa kuukiridwa, agalu otchedwa pike amatengedwa ngati nsomba zopanda vuto. Chosangalatsa ndichakuti, mwanjira imeneyi, agalu oyenda panyanja amatetezanso mazira omwe amaikira.

Mayendedwe osambira agalu a pike ndi ovuta kwambiri. Mitsempha yam'mbuyo ndi yam'mbuyo imagwirizana ndi zipsepse za pectoral ndi mchira poyenda kutsogolo. Agalu a Pike amasambira mwachangu komanso mwachangu, amasuntha mosadukiza pamitunda yayifupi, ndikusintha kolowera. Kusambira kwakanthawi kochepa sizomwe zimachitika pamitunduyi. M'malo mosambira m'mutu, agalu oyeserera amasambira mmenemo ndi mchira wawo kutsogolo kuti asatembenuke.

Chakudya cha galu wapanyanja.

Pike Pike galu ndi omnivorous zolusa. Amadya chakudya cholemera makilogalamu 13.6 kuposa kulemera kwa nsomba. Wobisalira uyu amalumpha m'malo ake kuti agwire nyama yake ndikugwira singano zake zakuthwa - mano - oterera, oyenda.

Kodi ndi zamoyo zotani zomwe galu wanyanja amakonda kudya kuthengo sizikudziwika. Mitundu ya nsomba yofananira kwambiri, monga agalu otchedwa tubeblennies ndi flagblennies ophatikizana, amadziwika kuti amadyetsa makamaka ma crustaceans.

Malo osungira agalu oyenda panyanja.

Kusindikiza pike sikuphatikizidwa mu IUCN Red List. Mtunduwu suwopsezedwa, kupatula chifukwa cha kuwonongeka kwa nyanja. Ngakhale nsomba zamtunduwu zimatha kudya nyama zikuluzikulu, kukwera kwa mchere m'madzi amchere kumatha kuchepetsa ngoziyi.
