Ответ:

Преобразование конечностей в ласты.

У (не учитывая черепах) обладающих ластами животных для движения служит прежде всего мощный хвост. В таких случаях ласты обычно выполняют функцию управления движением — играют роль рулей глубины и поворота.

Толстый слой подкожного жира

Толстый слой жира обеспечивает постоянную температуру тела и плавучесть, уменьшая удельную плотность.

Обтекаемая форма тела

Изменяя форму тела на такую, можно уменьшить турбулентное сопротивление во много раз.

"But what do you
make of this?" cried Professor Summerlee, triumphantly pointing to what
looked like the huge print of a five-fingered human hand appearing among the
three-toed marks. 

"Wealden!"
cried Professor Challenger, in ecstasy.  "I've seen them in Wealden in England. It is
a creature walking upright upon three-toed feet, and occasionally putting one
of its five-fingered forepaws down on the ground. Not a bird, my dear Roxton -
not a bird." 

"A
beast?" 

Nothing else could have left such a track.” 

His
words died away into a whisper, and we all stood in motionless amazement. Following
the tracks, we left the swamp and passed through some bushes and trees. Beyond was an open clearing, where there were five of
the most extraordinary creatures that I have ever seen.

There
were, as I say, five of them, two being adults and three young ones. Even the
babies were as big as elephants, while the two large ones were far beyond all
creatures I have ever seen. They had slate-colored skin, which was scaled like
a lizard's and shimmered where the sun shone upon it. All five were sitting up,
balancing themselves upon their broad, powerful tails and their huge three-toed
hind-feet, while with their small five-fingered front-feet they pulled down the
branches upon which they browsed. I do not know that I can bring their appearance
home to you better than by saying that they looked like monstrous kangaroos,
twenty feet in length, and with skins like black crocodiles. 



I do
not know how long we stayed gazing at this marvelous sight. A strong wind blew
towards us and we were well concealed, so there was no chance of discovery. From
time to time the little ones played round their parents in unwieldy gambols,
the great beasts bounding into the air and falling with dull thuds upon the
earth. The strength of the parents seemed to be limitless, for one of them,
having some difficulty in reaching a bunch of foliage which grew upon a
considerable-sized tree, put his fore-legs round the trunk and tore it down as
if it had been a sapling. This showed not only the strength of its muscles, but
also the weakness of its brain, for the whole tree came crashing down on top of
it. It yelped loudly, showing that despite its size there was a limit to what
it could endure. The incident caused him to move off, followed by its partner
and their three enormous infants. We saw the shimmering grey gleam of their
skin between the tree trunks and their heads moving up and down high above the
tree tops.

I looked at my comrades. Lord John was staring intently in the direction the
creatures had disappeared. The two professors were in silent ecstasy. In their
excitement, they had grabbed each other by the hand and stood like two little
children in the presence of a wonderful sight. Challenger's cheeks displayed a
broad smile, and Summerlee's ironic face softened in amazement.

«My God!» he cried at last.

"My dear Summerlee, I will tell you with great confidence exactly what
they will say," said Challenger. "They will say that you are a liar
and a scientific fake, exactly as you and others said of me."
