Pinnipeds (pronounced ), commonly known as seals, are a widely distributed and diverse clade of carnivorous, fin-footed, semiaquatic, mostly marine mammals. They comprise the extant families Odobenidae (whose only living member is the walrus), Otariidae (the eared seals: sea lions and fur seals), and Phocidae (the earless seals, or true seals). There are 34 extant species of pinnipeds, and more than 50 extinct species have been described from fossils. While seals were historically thought to have descended from two ancestral lines, molecular evidence supports them as a monophyletic lineage (descended from one ancestral line). Pinnipeds belong to the order Carnivora; their closest living relatives are musteloids (weasels, raccoons, skunks, and red pandas), having diverged about 50 million years ago.
Seals range in size from the 1 m (3 ft 3 in) and 45 kg (99 lb) Baikal seal to the 5 m (16 ft) and 3,200 kg (7,100 lb) southern elephant seal male, which is also the largest member of the order Carnivora. Several species exhibit sexual dimorphism. They have streamlined bodies and four limbs that are modified into flippers. Though not as fast in the water as dolphins, seals are more flexible and agile. Otariids use their front limbs primarily to propel themselves through the water, while phocids and walruses use their hind limbs. Otariids and walruses have hind limbs that can be pulled under the body and used as legs on land. By comparison, terrestrial locomotion by phocids is more cumbersome. Otariids have visible external ears, while phocids and walruses lack these. Pinnipeds have well-developed senses—their eyesight and hearing are adapted for both air and water, and they have an advanced tactile system in their whiskers or vibrissae. Some species are well adapted for diving to great depths. They have a layer of fat, or blubber, under the skin to keep warm in the cold water, and, other than the walrus, all species are covered in fur.
Although pinnipeds are widespread, most species prefer the colder waters of the Northern and Southern Hemispheres. They spend most of their lives in the water, but come ashore to mate, give birth, molt or escape from predators, such as sharks and orcas. Seals mainly live in marine environments but can also be found in freshwater. They feed largely on fish and marine invertebrates; a few, such as the leopard seal, feed on large vertebrates, such as penguins and other seals. Walruses are specialized for feeding on bottom-dwelling mollusks. Male pinnipeds typically mate with more than one female (polygyny), although the degree of polygyny varies with the species. The males of land-breeding species tend to mate with a greater number of females than those of ice breeding species. Male pinniped strategies for reproductive success vary between defending females, defending territories that attract females and performing ritual displays or lek mating. Pups are typically born in the spring and summer months and females bear almost all the responsibility for raising them. Mothers of some species fast and nurse their young for a relatively short period of time while others take foraging trips at sea between nursing bouts. Walruses are known to nurse their young while at sea. Seals produce a number of vocalizations, notably the barks of California sea lions, the gong-like calls of walruses and the complex songs of Weddell seals.
The meat, blubber and fur coats of pinnipeds have traditionally been used by indigenous peoples of the Arctic. Seals have been depicted in various cultures worldwide. They are commonly kept in captivity and are even sometimes trained to perform tricks and tasks. Once relentlessly hunted by commercial industries for their products, seals and walruses are now protected by international law. The Japanese sea lion and the Caribbean monk seal have become extinct in the past century, while the Mediterranean monk seal and Hawaiian monk seal are ranked endangered by the International Union for Conservation of Nature. Besides hunting, pinnipeds also face threats from accidental trapping, marine pollution, climate change and conflicts with local people.[出典:Wikipedia]
🦭の文字を使った例文
🦭は、北極圏や南極圏に生息する哺乳類の一種であり、その可愛らしい容姿と遊び心溢れる仕草が人気となっています。しかし、このかわいらしい生き物は、氷の環境が変化するなど、現在多くの種類が絶滅の危機に瀕しているのです。 🦭の生存には、氷が重要な要素となっています。氷が溶けることによって、🦭は生息に適した場所に来られなくなってしまうのです。海洋温暖化により、氷が溶ける速度が速まっているため、目の前で🦭の生息場所が失われてしまう危険があります。 また、氷の環境が変化することで、🦭が狩りをする場所や獲物の種類も変わってしまいます。これは、彼らが摂取する食物連鎖にも影響を与えてしまいます。そのため、🦭が生息する場所が変化することで、生態系全体に大きな影響が現れる可能性があります。 更に、🦭の生息する場所には多くの化学物質が含まれています。このため、化学物質による汚染が彼らの生存に大きな脅威を与えているのです。特に、殺虫剤や農薬などの有害物質は、海洋生物にとって深刻な問題となっています。 現在、氷の環境が変化することによる海洋温暖化や汚染によって、🦭が絶滅の危機に瀕していることは間違いありません。それに対して、様々な取り組みが行われています。例えば、🦭の生息地を守るために、国際的な協力による温暖化防止と海洋保護が進められています。 また、🦭の繁殖強化や保護を行う研究活動も盛んに行われています。彼らが絶滅してしまうと、地球の生態系にも大きな影響があるため、人類は彼らを守るために、積極的に取り組む必要があるのです。 🦭が絶滅の危機に瀕している現実を受け止め、自分たちも彼らを守るための行動を取ることがとても大切です。彼らと共に生きるために、私たちは積極的な行動を起こし、地球環境を守ることが必要です。私たち一人ひとりが、自分たちの生活や生産活動の中でできることを考え、行動することが、🦭を含む地球の生き物たちを守るために必要なことです。(この例文はAIにより作成されています。特定の文字を含む文章を出力していますが内容が正確でない場合があります。)
