Stop the brutal killing of some of the world’s cutest creatures.
Seals are among the most adorable creatures on Earth. They can be found on every continent but prefer colder climates to warmer ones. Just as their scientific name suggests, these animals are “fin-footed,” meaning they have feet that are shaped like fins. But seals are fascinating creatures for more reasons than their cuteness and feet.
Seals are part of a group known as pinnipeds, of which there are 33 known species. These include walruses, eared seals like fur seals and sea lions, and earless seals, also known as true seals. Don’t let the name fool you, though. Earless seals actually do have ears and can hear very well. Their ears are just hidden beneath their skin.

Speaking of skin, most seals have a very thick layer of fat, or blubber, under their skin. This is what allows them to survive in the freezing waters of the Arctic Circle and Antarctica. Arctic seals, for example, live in environments where the temperature drops below minus 40°C in winter.
In spite of that protective layer, not all seals look fat. Elephant seals, which weigh more than a truck, certainly do. However, at just around 50 kilograms, Baikal seals look relatively thin by comparison.

停止殘酷地殺戮世界上其中幾種最可愛的生物。
海豹是世界上最可愛的生物之一。牠們遍佈於各洲,但比起較溫暖的氣候,牠們偏好更寒冷的氣候。就如牠們的學名所示,這些是 「鰭足」動物,意思是牠們有形似鰭的腳。但海豹之所以成為迷人的生物並不僅僅是因為牠們的可愛和鰭足而已。
海豹隸屬一種被稱為鰭足類動物的群體,其下有三十三種已知物 種。這些包括海象、海獅科動物(eared seal,如海狗和海獅),以及 海豹科動物(earless seal,又被稱為 true seal)。然而,別被名字 給騙了(編按:海豹科動物的英文為 earless seal,字面上的意思為
「沒有耳朵的海豹」)。海豹科動物實際上的確有耳朵且聽力非常好。 牠們的耳朵只是藏在皮膚下面。
說到皮膚,大多數海豹皮膚下都有一層非常厚的脂肪,又稱作海 獸脂。這讓牠們得以在北極圈和南極洲酷寒的水中生存。例如,北極 海豹生活在冬季氣溫會降到零下攝氏四十度以下的環境。
即便有那層具保護性的脂肪,也不是所有海豹看起來都圓滾滾。 象海豹比一臺卡車還重,毫無疑問看起來圓滾滾。然而,只有五十公 斤左右的貝加爾海豹,相較之下看起來纖瘦許多。
