1
Those aren't cornflakes.
2
This rock is absolutely covered with tiny marine flatworms called acyles.
3
They're not just an animal.
4
They're also kind of a plant.
5
And they're practically immortal.
6
They use simple eyes called ocelli to seek out the sunniest spots on tropical coral reefs,
7
where they spread themselves out like beach blankets.
8
But they don't just lay around sunbathing all day.
9
Aseals are also skilled hunters.
10
They catch prey by engulfing them with their body and jamming them into their mouth.
11
You can see their meal trying in vain to escape.
12
Also, they don't have a butt.
13
Their poop just goes right back out through their mouth.
14
So you wouldn't want to kiss one.
15
They aren't just hunters.
16
These acyls are gardeners, too.
17
See those green dots?
18
Those are algae.
19
And those reddish cells belong to the acyl itself.
20
When the sun hits our flatworm friend, the algae inside produce sugars through photosynthesis.
21
This is a waste.
22
Researchers think they share those sugars with their host.
23
In return, the acyl provides its, um, waste, which is kind of like fertilizer for the algae.
24
And the acyl protects its houseguests.
25
Researchers think the acyls pack toxic chemicals in those reddish cells.
26
So predators tend to leave them alone.
27
Without its algae, the acyl would eventually die, even if it had plenty of prey to eat.
28
Scientists call a creature like this a Holobiant — a single being made up of two or more completely different species.
29
In this case, a solar -powered predator.
30
But that's not even the weirdest thing about them.
31
Researchers at Stanford University and the University of San Francisco are studying A -seals because of how they regenerate.
32
And to do that?
33
It'll be okay.
34
I promise.
35
You'd think getting cut in half would be a bad thing.
36
But within minutes, the wounded front half seals up.
37
In a couple days, it'll have a whole new tail. And the backside?
38
It doesn't just make a new head.
39
It makes two!
40
But it's hard to share one body with two heads.
41
So each half eventually pulls away from the other.
42
Where there was once one acyl, now there are three.
43
What seemed like a moment of doom was actually one of rebirth.
44
But they don't need the researcher's scalpel.
45
Aseals can drop their tail and clone themselves on their own.
46
The Aseal and its algae can multiply themselves like this over and over, indefinitely, making them functionally immortal.
47
Aseals can do this because they're packed with stem cells, which morph into any body part the Aseal needs to regrow.
48
And since they can't hunt until they grow new heads, they're extra reliant on the energy they get from their algae.
49
In these desperate times, the acyls even eat some of their algae.
50
Sorry.
51
Every relationship has its challenges.
52
But the acyl and its algae have a deal.
53
By taking advantage of each one's abilities, they're greater than the sum of their parts.
54
Hey, it's Laura.
55
Guess who else could be considered a holobiant?
56
You.
57
You've got a whole zoo of bacteria and other living things inside your gut that are vital to a healthy immune system, digestion, and even mood.
58
And if you want to keep
59
Deep Look healthy, support our show on Patreon.
60

61
Deep Look pint glass, and at $5 a month, a special Deep Look sticker.

Aussprache, auf die du achten solltest

Der Sprecher verwendet 20 Kurzformen und abgeschwächte Formen, zum Beispiel they're, don't, aren't. Sprich sie in der kurzen Form, so wie du sie hörst.

  • Die „th“-Laute: photosynthesis /ˌfoʊ.toʊˈsɪn.θə.sɪs/, rebirth /ɹiːˈbɜːθ/, sunbathe /ˈsʌnbeɪð/
  • Lange Wörter – auf die Betonung achten: practically /ˈpɹæk.tɪ.k(ə.)li/, indefinitely /ɪnˈdɛfɪnɪtli/, photosynthesis /ˌfoʊ.toʊˈsɪn.θə.sɪs/, regenerate /ɹiːˈd͡ʒɛnəɹeɪt/

Laute, die Deutschsprachigen schwerfallen:

  • /w/ — mit runden Lippen, nicht wie das deutsche „w“ (/v/): wound /ˈwund/, flatworm /ˈflæt.wəɹm/
  • Stimmhafter Auslaut — /b/, /d/, /g/, /z/, /v/ am Wortende nicht verhärten: mood /muːd/, wound /ˈwund/, backside /ˈbækˌsaɪd/
  • /æ/ — offener als „ä“: practically /ˈpɹæk.tɪ.k(ə.)li/, jam /ˈd͡ʒæm/, fabulous /ˈfæbjʊləs/, blanket /ˈblæŋ.kɪt/, acyl /ˈæ.sɪl/

So übst du mit diesem Video

  1. Höre dir das ganze Video einmal an, ohne zu sprechen, und notiere die Wörter, die du nicht kennst.
  2. Sprich Satz für Satz in normaler Geschwindigkeit nach und wiederhole jeden, bis dein Rhythmus zum Sprecher passt.
  3. Nimm dich auf und vergleiche mit dem Original; achte dabei auf Wörter wie researcher, hunter, tail.

Was ist die Shadowing-Technik?

Shadowing ist eine wissenschaftlich fundierte Sprachlerntechnik, die ursprünglich für die professionelle Dolmetscherausbildung entwickelt und durch den Polyglotten Dr. Alexander Arguelles populär gemacht wurde. Die Methode ist einfach aber wirkungsvoll: Du hörst englisches Audio von Muttersprachlern und wiederholst es sofort laut — wie ein Schatten, der dem Sprecher mit nur 1–2 Sekunden Verzögerung folgt. Anders als passives Hören oder Grammatikübungen zwingt Shadowing dein Gehirn und deine Mundmuskulatur, gleichzeitig echte Sprachmuster zu verarbeiten und zu reproduzieren. Studien zeigen, dass es Aussprachegenauigkeit, Intonation, Rhythmus, verbundene Sprache, Hörverständnis und Sprechflüssigkeit signifikant verbessert — was es zu einer der effektivsten Methoden für die IELTS Speaking-Vorbereitung und reale englische Kommunikation macht.
