Sailfish is lonely - he's playing with the sardines...
Awesome video! Amazing the swordfish didn't just swoop in and grab a mouthful from the mass, though.
Playing with his food.
Slow motion is pointless when the res is only 240P
Bad day at school . There`s always one bully .
No sardines
Well what the hell, I been fishing all my life and I had no idea what the bill was for. I wonder what carnage a sawfish wreaks with its snozzer now.
I thought they moved much faster?
He wasn’t hungry, but thinking about having shish kabob later
Now my mother would say if you don't quit playing with your food you're not getting any dessert
Great... We liked and enjoyed to the end. Thanks Have a happy day!
Just playing with his food.
still waiting the attack
Leave the fish alone!

Little square boxes
Those are sum big ass sardines lmfao
There's the reason they're also called swordfish,because that's what they got! And that'll mess anything up it gets busy let me tell ya,lol...
He needs to swing a lot harder than that!
Its a pointer in a school of fish
Cool vid they also make a grunting or clicking sound when balling bait
Hm. Either the sailfish isn't very hungry, or maybe he just doesn't like this brand of sardine? I didn't see him eat even one.
It probably ate most of them. They can only take so much. They slow down or get crippled. Those get picked off easily. Once they are schooled this tight it’s over. Especially if there is more than one.
Those aren’t sardines….
Very big sardines or very small sailfish !!
When it glitters under water you know it's magical
With that nose, he can't exactly sneak up in them.
Sorry charlie
Glad to see it didn't spear them. Then he'd be swimming around with a dead fish on his nose and no way to get at it.
All the fish are head down trying to hide in the school. It:s herd mentality with no source of leadership. A smart fish would bolt out of there. The others would follow. All dumb in the herd.
Omg he need to respect them 😂
Poor sardines. They either get killed by a bigger fish or end up in a metal can doused in oil.
Wow nice video kabayan hello FROM Philippines Walker 👣🏃🏃🚶📷🎥0
wat a war
Cool video! What is happening here? What kind of fish and what is it doing?
His mother should have told to never play with food
cRIKEYS MATE i DIDNT KNOW sARDINES GREW THAT BIG AND THANKS FOR SHARING.
I didn't know they used that to slash, I thought it'd stick the sardines. 🤡
A slash through a large group of targets is infinitely more consistent than trying to stab a singular, more agile small prey item...
@@iwasadeum I can only assume the tip of the spear is insanely sharp? Is the glittery shit from it scraping scales off of them?
Well at least he brought a can opener.
So... school massacres already existed in nature huh
Some attack...🙄🥱🤔
Those are pretty big sardines
No sardines, sailfish full.
Bullshit!!…Those are not sardines!! They never get that big!!!
Up to 12 inches
@@ThomasJones-ij6hv Those fish are definitely larger than 12’…Look at the size of the Sailfish!!
@@sticktrik could be a juvenile sailfish.
Those sardines are massive.
That was my first thought
I usually notice 3 sardine fish packed tightly into a small tin. I don't think any of these sardines would fit into any tins at all.
According to Wiki, one species of sardine, pilchards, can get up to 15.6 inches long, and live 25 years . . . as long as Swordfish don't move into the neighborhood, that is.
Wow
Putin
Looking for the spicy ones
Nice brother
