去哪可以看到大量野生的虎鯨?
就是想看看他們
虎鯨廣泛分布於全世界的海域日本北海(southen Japan),冰島(Iceland),對於水溫、深度等因素似乎沒有明顯的限制。它們在高緯度地區有相當高的棲息密度,特別是在獵物充足的海域。它們的移動情形普遍與追踨獵物或增加捕食率有關,時間通常在魚類產卵季與海豹的生產期。到了夏天,大西洋中大多數的虎鯨都棲息於浮冰邊緣或有浮冰的水道,以鬚鯨、企鵝、海豹等為食。它們會遷徙至何處、會移動多遠,目前仍未有定論。部分虎鯨會終年停留於南極海域,而在北極的虎鯨則很少接近浮冰。據華盛頓州與英屬哥倫比亞的虎鯨研究者指出,當地有定居型(esident)與過境型(tansient)兩種型態的虎鯨群,當地終年皆可發現此二種群體。部分個體有非常大的活動範圍,由各地的照片辨識結果發現,有些虎鯨的活動範圍自阿拉斯加(Alsaka)一直到南方的加州(Southen Califonia )。
先上圖:
2017年2月19日上午,有網友在朋友圈晒圖稱奉化區蒓湖鎮棲鳳雙山碼頭有兩條被漁民誤捕上來的鯨魚。通過照片記者看到,這兩條鯨魚約有4米多長,除肚皮和尾鰭一面為白色外,其他部位通體漆黑。
昨日,記者聯繫到了漁船船主林先生。2月16日,林先生名下的一艘漁船在東海一處海域誤捕到了這兩條鯨魚。「船上的人都說不上來這鯨魚是什麼品種,而且兩條鯨魚撈上來時就已經死了。」林先生告訴記者。當時,漁船的船老大沈師傅趕緊給他打了電話。一聽自家的漁船上捕到了鯨魚,林先生一邊和區海洋漁業局聯繫,一邊組織運輸船將鯨魚運到碼頭。2月18日下午,兩條鯨魚被送到了棲鳳雙山碼頭,這兩條鯨魚剛一「亮相」就引起了不少圍觀,通過漁業專家辨認,林先生才知道這兩條是虎鯨,是鯨魚中極為聰明的一個品種,壽命可達100多歲。林先生告訴記者,以前他的朋友也曾誤捕過一條虎鯨,但像這樣一網捕起了兩條卻是頭一遭。「這兩條鯨魚一條個頭稍小一些,它們可能是一對,才會一起被漁網捕了上來。」林先生說。隨後,記者從奉化區海洋漁業局了解到,這兩條虎鯨已於19日上午被送往南京師範大學用作研究標本。雖然有中國海域有虎鯨出現,但是生活在中國海域的虎鯨數量非常少,加上中國海域的漁業捕撈、對海洋的過度開發、污染破壞越來越嚴重,在中國海域虎鯨的生存環境每況愈下,虎鯨不適合長期在此生活,所以能發現他們的機會就更難了!筆者認為,要到中國一些遠離海岸,食物豐富,人類活動較少的深水海域才有機會發現虎鯨。當然這也是要運氣的,如果要去尋找虎鯨,在出發前最好瀏覽資料,去虎鯨出現過的地點,詢問當地保護海洋組織和研究人員、當地漁民,否則將是大海撈針。
國外觀野生虎鯨聖地有:紐西蘭、挪威、北美、阿根廷、澳大利亞。附送攻略:不想複製了,去關注微信號「虎鯨的旅程」,整理了很多。祝你如願
謝邀。我其實並未親眼見過呢…… 亞洲海域我基本玩的差不多了…… 不知道是分布少 還是我運氣不好…… 據說美國那邊多些。題主在哪裡?畫個範圍,我幫你打聽打聽
Range and habitat

Killer whales are found in all oceans and most seas. Due to their enormous range, numbers, and density, distributional estimates are difficult to compare,
[92]
but they clearly prefer higher latitudes and coastal areas over pelagic environments.
[93]
Systematic surveys indicate the highest densities of killer whales (&>0.40 individuals per 100 km2) in the northeast Atlantic around the Norwegian coast, in the north Pacific along the Aleutian Islands, the Gulf of Alaska and in the Southern Ocean off much of the coast of Antarctica.
[92]
They are considered "common" (0.20–0.40 individuals per 100 km2) in the eastern Pacific along the coasts of British Columbia, Washington and Oregon, in the North Atlantic Ocean around Iceland and the Faroe Islands. High densities have also been reported but not quantified in the western North Pacific around the Sea of Japan (in very limited areas), Shiretoko Peninsula and off Kushiro (Resident and Transient groups began colonizing in these areas possibly after in 2000s), Sea of Okhotsk, Kuril Islands, Kamchatka and the Commander Islands and in the Southern Hemisphere off the coasts of South Australia, off the coast of southern Brazil and the tip of southern Africa. They are reported as seasonally common in the Canadian Arctic, including Baffin Bay between Greenlandand Nunavut, and around Tasmania and Macquarie Island.
[92]
Information for offshore regions and tropical waters is more scarce, but widespread, if not frequent, sightings indicate the killer whale can survive in most water temperatures. They have been sighted, for example, in the Mediterranean, the Arabian Sea, the Gulf of Mexico and the Indian Ocean around the Seychelles.
[92]
In the Mediterranean, killer whales are considered "visitors" with the exception of one small population which lives in the Strait of Gibraltar.
[94]
A distinct population may also exist in Papua New Guinea.
[95]
[96]
Distributions and abundances in other Aisan waters are very unclear, only with sightings time to time have been reported, such as off Phuket
[97]
and Mergui Archipelago.
[98]
Population structure in mid to lower latitudes of the North Pacific is unclear especially in coastal waters. Large concentrations are known to occur north of the Northern Mariana Islands
[99]
and in the Gulf of Sendai,
[100]
and repeated sightings are reported off Bali,
[101]
the east coast of Taiwan, Ryukyu Islands,
[102]
Izu Islands,
[103]
in Tsushima Strait,
[104]
and Izu Peninsula.
[105]
The modern status of the species along coastal mainland China and its vicinity is unknown. Recorded sightings have been made from almost the entire shoreline; from Bohai and the Yellow Sea in the north to the Zhoushan Islands in the east
[106]
and the Vietnam coast in the south.
In the Antarctic, killer whales range up to the edge of the pack ice and are believed to venture into the denser pack ice, finding open leads much like belugawhales in the Arctic. However, killer whales are merely seasonal visitors to Arctic waters, and do not approach the pack ice in the summer. With the rapid Arctic sea ice decline in the Hudson Strait, their range now extends deep into the northwest Atlantic.
[107]
Occasionally, killer whales swim into freshwater rivers. They have been documented 100 mi (160 km) up the Columbia River in the United States.
[108]
[109]
They have also been found in the Fraser River in Canada and the Horikawa River in Japan.
[108]
Migration patterns are poorly understood. Each summer, the same individuals appear off the coasts of British Columbia and Washington. Despite decades of research, where these animals go for the rest of the year remains unknown. Transient pods have been sighted from southern Alaska to central California.
[110]
Population
Worldwide population estimates are uncertain, but recent consensus suggests an absolute minimum of 50,000.
[2]
[38]
Local estimates include roughly 25,000 in the Antarctic, 8,500 in the tropical Pacific, 2,250–2,700 off the cooler northeast Pacific and 500–1,500 off Norway.
[111]
Japans Fisheries Agency estimated 2,321 killer whales were in the seas around Japan.
