how you interact with sharks is everything blues are not aggressive to human beings
but they're very very inquisitive and the only real safety equipment we have
are gloves to make sure that my fingers don't look like tempting little fishes
our first blues underwater and they definitely aren't camera shy
by allowing them to come to us and not making any sudden movements
we allow the sharks to get confident
and more and more start appearing
i've never seen this many blue sharks in one place
this is just unbelievable this is the most beautiful of all sharks and the first thing is
its color they're called blue sharks for a reason that deep deep blue that gives them their name
it's not just to make them look pretty it's part of a camouflage scheme called counter shading
so when you look down on them from above with the deep deep blue
of the ocean beneath they just disappear even a big animal can vanish completely
conservatively a dozen big blues circling around us right now
it's so rare to see so many at the same time i feel incredibly lucky and what makes these sharks
such deadly predators is that they are phenomenal ocean swimmers the number one thing the thing that
makes this shark better than any other at that open ocean movement are those extraordinary fins
the pectoral fins are the biggest for its size of any shark and moving through the water they give
it lift just like the wings of a plane blues are the most widespread of all shark species
using their pectoral fins to glide through the water they can travel vast distances while using
minimal energy keeping that energy to catch a huge variety of prey from squid to shrimp to fish
in fact blue sharks have been known to travel up to 10 000 kilometers a year
that's like us swimming from london to new york and back
but those fins might also be their biggest downfall
right now the blue is probably the most heavily fished species of shark in the world
hunted mainly for their fins which are used in traditional medicine and food
and here in the north atlantic it is right on the brink this extraordinary creature
the most beautiful shark found in our seas could be at risk of extinction because of us
their survival isn't just important for the sharks themselves but for the health of our oceans
it's all kicking off here now they're getting very frisky
there's there's one big female here with a dark semi-circle around her gills and it's
it's a mating scar where she's been bitten by a male because of that the females have skin
that can be three times thicker than the males to protect them but she has certainly got attitude
sharks are deadly predators and adapted to be hunters first and
foremost but they're also very misunderstood
it's experiences like this which makes sharks one of my favorite animals on the planet this ranks
for me is the best british wildlife encounter i have never seen anything like this before
able to cruise for hundreds or even thousands of miles in the search for food and with
those big broad pectoral fins giving it lift and making it energy efficient
there is no doubt that the blue shark is deadly
a speedy pack hunter which can swim thousands of kilometers just for a meal
the blue shark is definitely deadly
