the ocean is a pretty dangerous place

00:03

be it the massive waves strong currents

00:05

or freezing waters

00:07

oceans really do have the potential to

00:09

dispose of you

00:10

in an instant today we're venturing

00:13

into the murky waters here are the top

00:15

15 most dangerous types of fish

00:18

ever found number 15

00:22

needle fish measuring in at just one

00:24

meter long and weighing just four

00:26

kilograms

00:27

needle fish are a lot more dangerous

00:29

than they look

00:30

that's because these fish not only have

00:32

a long sharp and bony beat

00:34

but also have a tendency to leap out of

00:36

the water at its speeds of up to 60

00:38

kilometers per hour

00:40

unfortunately this has made them a true

00:42

terror in their indian and pacific ocean

00:43

habitats

00:44

they're attracted to lights from boats

00:46

and will often leap out and impale

00:49

unsuspecting sailors as a result they

00:51

are widely considered to be even more

00:53

dangerous than sharks to fishermen

00:55

who work in needlefish infested areas

00:59

number 14 stingray as the name suggests

01:03

stingrays stand out due to them having a

01:06

stinger near the base of their tail

01:08

while they are usually docile they don't

01:10

hesitate to use said stinger

01:12

when they're threatened typically

01:13

speaking this only occurs with humans if

01:15

one has accidentally stepped on

01:17

as they tend to burrow under the sand as

01:19

camouflage in order to ambush prey

01:22

unfortunately these stings are usually

01:24

extremely painful and often cause

01:26

secondary symptoms such as local tissue

01:28

death nausea

01:29

vomiting diarrhea and muscle cramps

01:32

yet while smaller stingrays likely will

01:34

not kill you larger species can pose a

01:37

very real threat

01:38

most notably famed ecologist steve irwin

01:41

learned this the hard way in 2006

01:43

when he unfortunately passed away after

01:45

coming into contact

01:46

with a two meter long bull stingray as a

01:49

result we'd recommend swimming in the

01:51

other direction if you see one

01:52

on your next tropical vacation

01:56

number 13 giant moire eel

01:59

although there are over 200 different

02:01

species of moray eel

02:02

the giant moray eel is certainly the

02:05

most troublesome

02:06

found throughout the indian and pacific

02:08

oceans they can reach up to three meters

02:10

in length and weigh as much as 30

02:11

kilograms

02:13

while they're not all that aggressive

02:14

due to them spending most of their time

02:16

in the burrows

02:17

they can do some serious damage when

02:19

divers attempt to feed them

02:21

as they will sometimes lunge forward and

02:23

bite off the fingers of said divers

02:25

as a result we'd recommend staying far

02:28

far away from them on your next scuba

02:30

diving adventure

02:32

number 12 barracuda

02:36

found in the oceans worldwide the

02:38

barracuda is an

02:39

apex predator that has the potential to

02:41

dish some serious damage

02:44

reaching lengths of up to 2 meters and

02:45

weights of up to 50 kilograms

02:47

the barracuda is absolutely massive and

02:50

it also sports a set of

02:52

sharp teeth in order to chomp down on

02:53

its prey but generally speaking

02:56

barracudas are harmless to us humans as

02:58

they typically only attack other fish

03:01

however in murky waters they have been

03:03

known to bite the arms and legs of

03:04

humans after mistaking them for the

03:06

underbelly of a fish

03:08

they've also been known to chomp down on

03:10

shiny objects such as belt buckles

03:12

necklaces and earrings

03:13

as a result these beastly barracudas

03:16

really can

03:17

be quite bothersome

03:18

03:20

11 angler fish when it comes to deep sea

03:24

creatures

03:24

few are as frightening as the angler

03:27

fish

03:28

although only about the size of a coffee

03:30

cup they have a pretty frightening

03:31

appearance

03:32

with the 200 different species of them

03:34

each featuring a prominent lure that

03:36

hangs off their front end

03:38

it uses this lure to attract prey once

03:41

said prey is close enough

03:42

it will clamp down onto it with its
