Kuonekwa

Inogona kukura kusvika masendimita makumi maviri kureba. Ine musoro wakati kurei, iyo yakati kurei kupfuura muviri pachawo. Inosiyaniswa nemuromo mukuru uye miromo mikuru, pamwe nemaziso makuru, ane tsvuku tsvuku. Iko hakuna zviyero pamuviri, asi zvidiki, asi zvakapinza zvipikisi zvinoiswa muviri wese kudzivirira kubva kuvavengi. Panyaya iyi, zvikara zvishomanana zvinoshinga kudya mhuka dzinobaya zvakadaro.

Iine mapectoral fins akareba akafukidzwa nemavara madiki madiki. Munzvimbo yegill mune zvidziviriro zvekudzivirira zvakafukidzwa neamwechete prickly spines. Kuseri kwebullhead kwakapendwa grey-yellow nemakwapa ebrown nemitsetse. Izvi zvinobvumira hove kuti dzirambe dzisingatarisirwi pamusana pematombo, iyo inodzivirira inoshanda kune vavengi vayo vepanyama.

Habitat

Iyi hove diki inogara mumvura yakachena yeEurope, Asia neNorth America, iyo iri panzvimbo yakakwirira yemamita akati wandei pamusoro pegungwa. Panguva imwecheteyo, madhamu chete ane mvura yakachena uye yakawanda yeokisijeni yakakodzera kugarwa kwesculpin. Inonyanya kukodzera nzvimbo dzine pasi pematombo, apo yakanyatsovharidzirwa nekuda kwemavara ayo akasiyana.

upenyu

Iyi hove duku inowanikwa mukati memahombekombe egungwa, umo mvura yakachena inopararira. Anogona kugara munzizi diki, dzine pasi pematombo. Inotungamira, sekutonga, mararamiro ega. Inofarira kuomerera kunzvimbo dzekugara, kwete kufamba nzendo refu.

Masikati, inovanza pakati pevanoisa matombo, kubva kwayakagamuchira zita rayo semuvezi. Kana kwasviba, hove dzacho dzinosiya nzvimbo yadzinenge dzakavanda dzoenda kunovhima dzichitsvaka zvokudya. Zvinenge zvisingabviri kuona hove mumvura, nokuti ine ruvara runoenderana, inobatanidza nemuvara wepasi. Ihove iyi inoonekwa seine usimbe, nekuti inoshambira zvishoma, ichiita isingafambi. Panguva imwe chete, paanenge ari mungozi, anogona kukurumidza kufamba, kunyange kusiri kure, kusvika kumiganhu yepokugara iri pedyo. Iyo sculpin inosanganisirwa mukudya kwetrout.

Kazhinji, mukati medhamu, hove iyi inogona kuwanikwa munzvimbo yemarasha, munzvimbo dzisina kudzika. Munguva yekubereka, inodzivirira zvakanyanya nzvimbo yayo yekugara uye vana.

Kubereka

Pane imwe nzvimbo mugore rechina kana rechishanu rehupenyu, sculpin inogona kutotanga. Panguva imwecheteyo, vakadzi vashoma zvikuru kupfuura varume, izvo zvinotungamirira kumakwikwi makuru pakati pevarume.

Zvichienderana nemhando yedhamu uye nzvimbo yaro, nguva yekuberekesa inoitika mukupera kwaApril kana kutanga kwaMay.

Isati yabereka, hono imwe neimwe inogadzirira nzvimbo nokuchera kakomba kekuti hadzi yokukandira mazai ayo. Sezvo mutemo, panguva ino unogona kuona "kurwa" kwese pakati pevarume, zvose zvenharaunda uye zvevakadzi.

Pane imwe nguva, hadzi inokandira mazai asingasviki mazana matatu. Panguva imwecheteyo, mazai anosiyaniswa ne-yellowish-pink tint uye hukuru hukuru.

Munguva yekuberekesa, mukadzi anogona kuita zvimedu zvakawanda, mumakomba akagadzirirwa evarume vakasiyana, mushure mezvo, varume vanoshingaira kudzivirira clutch kusvikira fry ichioneka. Mushure memavhiki 3-4, fry inogona kuonekwa, kunyange zvazvo zvakawanda zvinoenderana nemamiriro ekupisa. Hadzi inokandira mazai ayo pasi pedombo, ichinamira pariri. Mushure maizvozvi, murume anovachengeta, achibvisa guruva, tsvina nemarara, achigara achivaputira nezvimbi.

Munhu anonyangira anodyei

Kudya kwehove iyi kwakasiyana-siyana, saka inoda:

Pamusana pekuti nzizi dzakasvibiswa pamwero wepamusoro, nhamba yesculpin iri kudererawo. Tichifunga kuti hove iyi ine basa guru mukudyara kwemarudzi akawanda ehove, munhu anogona kungofungidzira kuti kutsakatika kwehove iyi kwakakomba sei.

Kana tembiricha yakadzikama ichikwira, sculpin inosiya kana kunyangarika kubva mumadhamu mazhinji. Huwandu hwehove iyi yakasarudzika inodzoreredzwa zvishoma nezvishoma, mumwaka yakati wandei. Panyaya iyi, hove iyi yakanyorwa muRed Book yeRussia uye inorondedzerwa semhando isingawanzoitiki yehove.

Pasinei nezvimwe chokwadi, dzimwe nguva maamateur anglers anobata hove iyi. Nekuda kwemavara ayo anoshamisa, iyo yakajairika sculpin yakaoma kuona inopesana neshure kwepasi. Anogona zvakakodzera kunzi inyanzvi yekuvanza, iyo inowanzoponesa hupenyu hwake. Asi nekuda kwekuti madhamu anogara akasvibiswa, uye tembiricha yemvura inokwira pamusoro pezvakajairika, sculpin inogara ichinyangarika kubva kune akawanda emvura.
