WHAT DOES THE OCEAN SOUND LIKE?

“Did you know that dolphins talk?”
“I did, but I don’t know what they say.”
“They talk of trading ships and cargo,
Of seas and oceans far away,
Of where to find the finest fish,
And how much you should pay!”

— Yuliy Kim

HOW MUCH WATER IS IN YOU?

ASSEMBLE THE ANIMAL

Displayed here are various marine creatures. Each group possesses its own distinct swimming style.

Marine mammals swim by leveraging their powerful back muscles. Their horizontal tail flukes move up and down – acting just like swim fins underwater.

Fish propel themselves using their tails and their entire bodies, flexing from side to side, while their fins act as rudders for precise steering.

Cephalopods (such as squids and octopuses) utilize jet propulsion: they draw water into their mantle cavity and forcefully expel it outward, driving themselves forward.

What do they all have in common? They all share a streamlined body shape! The smoother the body, the easier it is to slice through the water. This is why they are all classified as nekton – the collective scientific term for actively swimming ocean dwellers capable of navigating independently over vast distances.

Baleen plate of a Bowhead Whale

Balaena mysticetus Linnaeus, 1758

Right Whales – Family Balaenidae

The bowhead whale possesses the largest mouth in the animal kingdom, housing up to 400 baleen plates on each side, with some reaching up to 4.5 meters in length.

Despite its monumental size, the whale does not hunt large prey. Instead, it feeds on microscopic planktonic organisms, filtering them directly through the fringed edges of its baleen.

趣味问答

大海的声音是怎样的?
- 海豚会说话这件事你知道吗?
我知道,可我不知道它们在聊些什么。
- 聊商队、聊海洋,
哪里有鱼,价值几何。

拼出海洋动物

这里描绘了不同的海洋动物。

每个群体都有自己的游泳方式。

海洋哺乳动物依靠背部强壮的肌肉游泳。它们水平的尾巴上下摆动——就像水下的鳍一样。

鱼类摆动全身与尾鳍左右扭动,鱼鳍充当舵,完成转向。

头足类(鱿鱼、章鱼)使用喷射推进: 水吸入外套腔,再猛烈向后喷出,推动身体前进。

它们的共同点是什么?

全部拥有流线躯体!身体越光滑,就越容易破浪前进。因此,它们都属于游泳生物——这是对能够独立移动较长距离的海洋居民的称呼。

弓头鲸须

Balaena mysticetus Linnaeus, 1758

弓头鲸科 Balaenidae。

弓头鲸拥有动物界最大的嘴,嘴两侧各排布400片鲸须板,单片最长可达4.5米。

它并不捕食大型猎物,依靠鲸须板的流苏过滤微小浮游生物为食。
