Sea Predators Hate This Fish and Here Is Why

Sea Predators Hate This Fish and Here Is Why | marine predators are too cunning to stay
hungry dolphins toss fish out of the
water to stun it whales create bubble
traps and orcas have perfected their
hunting skills prey simply couldn’t win
against such odds until evolution took
its side
how to avoid falling prey to a shark you
can find plenty of recommendations on
the internet about this but the most
obvious way is well get out of the water
things get a little more complicated
when you’re a fish you don’t want to get
out on land just yet and have no desire
to become a dinner of the sea predator
either you have to get creative and so
the flying fish learned to fly turned
out rising above the water surface was
enough to outrun mackerel tuna swordfish
marlin and other large hunters who would
not mind eating you a perfect defense
the mechanism for someone who’s not grown
thorns or poisonous skin or can’t
pretend to be a stone
huh well how do you like that though how
useful is this escape strategy in
general it’s cool when you fly over the
abyss and your enemies stay on the other
side or if you’re at least separated by
a wall but a flying fish still lands in
the water and in the seas there are
usually no barriers of any kind at least
at great depths wouldn’t it be easier to
sail away really quick it may seem weird
but the speed of a flying fish in the
water is lower than in the air that is
it literally flies faster than it swims
nature are you okay no wonder predators
do not expect this turn of events about
43 miles per hour by air about 37
underwater we’re talking about a common
fish with a tail gills and fins when
escaping a flying fish can rise up to
four feet high above the water after
that it moves forward in a very peculiar
way covering up to 1312 feet then the
flight or rather gliding is over but
only for the fish to dive accelerate and
take off again the cycle can repeat up
to 12 times and each time the speed is
really great well many electric scooters
move slower than that hey get out of the
of course simply jumping out of the
water would not be enough for such a
long flight try to repeat that you won’t
even cover three feet all because people
unlike flying fish simply do not know
how to properly use water and air for
their purposes without additional tools
airplanes ships and surfboards are cool
but we’re too heavy to catch the
currents of air and use them to prolong
our flight and let’s be honest the human
body does not have a very good shape in
terms of aerodynamics my back
oh my back the flying fish was lucky
life in the water had already made it
streamlined there were only a few
details left to add like special fins
and tail as it rises the flying fish
begins to steer quickly flapping its
tail while still underwater then it
overcomes the water resistance and takes
off spreading its extended fins which
help the fish float above the water
surface when a flying fish approaches
the surface again it can flap its tail
and steer without completely submerging
back into the water this all happened so
quickly that biologists could not
determine the way the fish moved for
decades was it flapping its fins like a
bird or did it use some other technique
high-resolution photos of flying fish
appeared only in 1941 though people have
known about the existence of flying fish
since antiquity you see how many years
it took for humanity to figure
everything out mediterranean sailors of
the past used to think flying fish
returned to shore at night to sleep that
is first they finished their shift as
well fish and then they rest on land
well yeah i can easily imagine that the
day is finally over i can take a nap now
though actually what i really want to
know is what happens to the gills of a
flying fish when it travels long
distances through the air they probably
get dry during the flight and for any
other fish this means certain death well
flying fish know how the gills work they
also know very well that evolution has
not given them any lungs so it’s better
not to even try breathing while you’re
in the air yes flying fish simply hold
their breath closing their gill covers
not to get too dry if you think about it
there’s nothing strange about this
people have learned to hold their breath
when they dive so why shouldn’t the fish
do the same fortunately they don’t need
something like swimming goggles the eyes
of the flying fish have evolved to see
both underwater and in the air without
squinting okay let’s say we figured out
what helps the flying fish fly but how
could a fish learn to fly anyway i mean
it’s a fish apparently this is a really
good way to stay safe from predators
because this is not the first time fish
came up with it the earliest known fish
capable of flight belong to the
thoracopterids and live from 235 to 242
million years ago but it did not evolve
into a more modern form these fish are
not related in any way the ancient one
died out along with the rest of the
prehistoric animals and then about 65
million years ago new flying fish began
to appear if they knew evolution had
done this way before they appeared they
would probably be upset well who wants
to do something a second time when you
can just copy someone else’s work but in
nature it happens all the time most of
the creatures that can or could fly
evolved independently from each other
insects bats birds and pterosaurs
evolved on their own without sharing a
common ancestor and since all this
happened with different species at
different times independently does this
mean anyone can learn to fly in theory
yes of course this will take a very long
time but if flight becomes a cool and
irreplaceable feature for an animal from
the evolutionary perspective it’ll grow
wings there are various theories on how
the wings appeared according to one of
them the first feathered dinosaurs waved
their front legs while running which
allowed them to accelerate even more and
in the end they just got too carried
i have no idea what’s going on right now
according to another theory the animals
learned to fly with the help of trees
ancient pterosaurs jumped from one
branch to another and over time their
bodies were transformed in order to
cover ever more distance by the way
flying squirrels evolved the same way
they appeared 18 to 20 million years ago
and began to fly to get to food faster
imagine climbing down from one tree then
running to another one then climbing to
the branch someone will have enough time
to steal your nuts it’s much easier to
fly from tree to tree otherwise no food
will replenish the energy you spent
while running back and forth imagine if
batman moved everywhere on foot he’d be
damn exhausted too
19 more blocks but flying from tree to
tree and flying after jumping out of the
water are completely different matters
and not only because we talk of
different animals these flights also
have completely different goals flying
squirrels usually fly to get food which
means they replenish energy flying fish
rise into the air trying to escape from
the predator that is they only spend
energy in addition they have to overcome
the resistance of the water every time
not the easiest thing to do especially
if you’re a small fish
the same time it’s believed that flying
over water is easier the closer the
flight is to the surface the stronger
the so-called ground effect large birds
for example pelicans feel it especially
well the effect comes in action when the
bird is within its full wingspan away
from the surface of the water the air
seems to funnel between the lower
surfaces of the wings and water it’s
thereby compressed and acts like a dense
cushion that supports the bird aloft a
sort of a bonus to conventional
aerodynamic forces well i never found
accurate information where it’s easier
to fly over water or land because the
the ground effect works in both cases the
scientists as always are not certain of
anything but here’s a fact for you
during world war ii long-range bombers
often flew close to the surface of the
water to save fuel they knew how to use
the ground effect to their advantage but
back to the flying fish to avoid
underwater predators, they started flying
over the surface however, this turned out
to be not the safest place ha these
predators are total fools
frigate birds love eating flying fish
especially since they don’t even have to
dive after it the prey literally jumps
right into their beaks favorite food
delivered straight to you and it seems
like some of the frigate birds are so
lazy they no longer even look for fish
themselves but simply steal it from the
fishermen. see you later.
