Outlines
π The Amazing World of Ants
This paragraph introduces the vast history and population of ants, which have been on Earth for 110 to 130 million years, far longer than humans. With an estimated population of 10 quadrillion, ants' collective biomass is comparable to that of all humans combined. The success of ants is attributed to their ability to function as a super organism, with each ant performing a specific task. The queen's primary role is reproduction, laying thousands of eggs, while the colony consists mainly of sterile females serving as soldiers, foragers, or caretakers. Male ants, or drones, exist solely to mate with the queen and then die. Ants communicate through an impressive array of pheromones, with 10 to 20 different signals that can be incredibly powerful, as demonstrated by a video of a queen being eaten alive by a crab spider while still attracting mates. The paragraph also highlights the unique adaptations of various ant species, such as the leaf cutter ants' agricultural practices, honeypot ants' food storage capabilities, and army ants' coordinated attacks. It concludes with a discussion of invasive species like the Argentine ants and the yellow crazy ants, which have caused significant ecological damage in new environments.
π₯ The Battle Against Invasive Ants
The second paragraph delves into the challenges posed by invasive ant species, particularly the aggressive red fire ants in the United States. These ants are known for their painful stings, which can cause necrosis and, in rare cases, death. The paragraph introduces the raspberry crazy ant, which has developed a chemical defense mechanism against the fire ants' venom. This species counters the fire ants' stings by secreting formic acid, which neutralizes the alkaloid in the fire ants' venom. Despite the potential of the crazy ants to help control the fire ants, they also present their own problems, such as their tendency to invade homes and interfere with electrical appliances. The paragraph concludes with a note on the slow but steady spread of these invasive species, highlighting the ongoing battle against them and inviting viewers to suggest which animal to feature in the next episode of 'Animal Logic'.

the ants go marching one quadrillion by
one quadrillion hurrah
[Music]
hurrah hi I'm Danielle defo and you're
watching animal logic homo saion have
been on the planet for about 200,000
years on the other hand scientists
estimate ants have been around for about
110 to 130 million years sounds more
like a human infestation to me there are
over 7 billion people on the planet a
rough guess puts the ant population at
10
quadrillion that's 10 with 15 zeros if
you added them all together in one big
ball their biomass would be about the
same weight as all of us humans combined
possibly the greatest reason for the ant
success is their ability to function as
a collective whole on their own each ant
does one small very specific thing but
when they come together they form a
super organism kind of like Megazord the
Queen's role is to reproduce often
laying thousands of eggs during her rign
the rest of the colony is mainly made of
sterile females who are typically either
soldiers forgers or caretakers of the
queen and her eggs the males or drones
only job is to inseminate the queen and
then usually die all of this is
orchestrated by the ants incredible
pheromones of which they're limited to
between 10 and 20 different signals to
give you an idea how strong these
messages are this is a video of a queen
being eaten head first by a crab spider
The Mating pheromone the queen is giving
off is so strong that the mail drones
swarm over her continually mating with
her even though the situation does not
look too promising it's truly chemistry
the over 14,000 species of ants may have
had some common traits but what is truly
amazing are their unique adaptations the
leaf cutter ant can carry 50 times its
weight harvesting pieces of leaves to
fertilize nourishing fungus the largest
Leaf Cutters carry the leaves the medium
ones cut them into pieces and the
smallest tend to the fungus inside
special agricultural chambers within the
anthills Honeypot ants store food and
liquid in their abdomen and can reach
the size of grapes they're like a
Movable Feast when other ants need
nourishment they rub the bloated ants
antenna and it regurgitates its load for
everyone to eat
yum the notorious Army ant attacks in
groups of 100,000 or more feeding on
everything in their path including bugs
small reptiles and even on the rare
occasion large vertebrates they are
almost always on the Move having only
temporary Burrows slav making ants
kidnap the eggs and Young from other ant
colonies and then force them to excavate
their nests find food and care for their
queen or sometimes they just eat them
the fire ANS that live in Brazil deal
with flooding by creating a living raft
they hook their legs and mouths together
and Float carrying the queen safely on
top until the flood subsides sometimes
for weeks unfortunately the an's ability
to adapt to its environment starting to
get a little scary as they begin their
path to world and Hollywood dominance
the Argentine ants hives are swarming
across the planet they have invaded six
continents in the last century
established ing themselves in over 15
countries the main reason for their
dominance is that unlike other species
of ants if they come across a foreign
colony of Argentine ants they won't
fight them they will join together and
create super colonies they have claimed
land that stretches for 6,000 kilm
across the coast of the Mediterranean
California and Japan sadly it is often
humans that spread the invasive ants
bringing them to places that have no
existing ant populations the yellow
crazy ant
most likely brought on board container
ships invaded Christmas Island in the
Indian Ocean in the 30s and has never
looked back it now has the highest
recorded density of forging ants with
2,000 per square meter and they are
wrecking Havoc the yellow crazy ants
have killed between 15 and 20 million of
the Native red crabs that live on the
island because guess what this species
of ant can shoot formic acid basically
they shoot the acid in the eyes of the
crab and blind it the crabs start
frothing at the mouth and then die
within a few hours and the ants eat them
from the inside out the yellow crazy
ants have been spreading to other
Islands as well where they use similar
techniques for attacking their prey most
notably invading birds nests and
shooting their acid on the baby birds
burning and deforming them ants are a
fun time however the king or rather the
queen of the invasive ant is the
imported red fire ant in the us alone
the FD a estimates that5 billion a year
is spent fighting the fire ant
infestation these fire ants are far more
aggressive than most ant species they
respond to the pheromones of the first
ant that attacks thereafter attacking
together in Mass sometimes even against
humans their sting is extremely painful
with their venom composed of a
necrotizing alkaloid to humans this
means the formation of white pules lots
of cursing and a few rare cases of death
to other insects it almost always means
death there is hope however another
crazy ant this time the raspberry or
tauny crazy ant has developed a chemical
defense against the fire ants Venom in
battle when the fire ant dishes out its
lethal sting this species of crazy ant
Rises up on its high legs secretes its
own formic acid onto its abdomen and
spreads it all over its body
counteracting the fire ants alkaloid war
war never changes after after many
attempts to push back the fire ants by
humans it appears that these raspberry
Crazy Ants are starting to win the war
time for a
celebration not really although the
crazy ants bite is not nearly as bad as
the fire ants they unlike fire ants love
to come into homes and are very
attracted to electrical appliances often
shorting out phones air conditioners and
other devices also they multiply faster
than fire ants and don't respond to the
same poison
the deadly Ant Invasion is still moving
slowly towards us advancing 300 ft a
year okay that's not that fast we have
some time what animal should I check out
next please let me know in the comments
as usual and be sure to subscribe for
new episodes of animal logic every week
