number 10 sea snakes between 30 to 50 species of snakes of the family a lapiday are adapted for
marine life save a couple of specific sub-families these snakes are all venomous and are unable
to move on land they are found in warm coastal waters from the indian ocean to the pacific ocean
among all existing families and subfamilies of snakes sea snakes are some of the most venomous
given the large number of species that make up the sea snake family these serpents come in a variety
of shapes and sizes however in general they have compressed bodies similar to eels and paddle-like
tails which help them to swim unlike fish they lack gills as such they have to resurface now and
then to breathe air they grow between four to five feet in length and have unique sensory abilities
that help them hunt in water what makes them dangerous is their venom which can cause serious
symptoms that result in death in spite of this not all of them are aggressive and tend to stay away
unless provoked they usually eat small fishes and tiny octopuses however they often mistake divers
for mating partners leading to grisly encounters that may escalate into snake attacks in fact harry
evans a fisherman in australia was bitten and killed by a sea snake on one of his expeditions
he was originally from the uk and had moved to australia to live his dream as a trawler fisherman
by the time emergency services got to him it was too late and the snake had gotten away number nine
polar bears seeing polar bears on this list might cause you to raise an eyebrow we all
know them to be land mammals however these creatures spend most of their lives at sea
they are incredibly strong swimmers and have been spotted hundreds of miles away from land they have
been labeled by scientists as hyper carnivores having a strong preference for meat polar bears
commonly live within the arctic circle including the arctic ocean and the surrounding land masses
they have evolved specific features to help them survive within extremely cold habitats
adult male polar bears typically weigh pounds to 1500 pounds they also stand as high as 7 to 10
feet tall females are typically half the size of males just about everything makes these creatures
dangerous ranging from their large size to clawed hands to their powerful bite to their speed they
can run 25 miles per hour although they are faster in water they also tend to eat seals and fish
meaning that they hunt in water meaning that they might run into any unsuspecting human divers in
fact in scenario jack canada three people were attacked by a polar bear they managed to kill
the bear but sustained heavy injuries themselves it took a while for emergency services to arrive
at the small town after which the victims were transported to other health centers for greater
medical care number eight cone snail cone snails are a large group of extremely venomous predatory
sea snails their venomous sting occurs without warning and can be quite fatal to humans they use
a hypodermic needle-like modified radula tooth and a venom gland to attack and paralyze their prey
before engulfing it the tooth which is sometimes likened to a dart or a harpoon is barbed and can
be extended some distance out from the head of the snail at the end of the proboscis there are over
900 species of cone snails and most of them can be found in tropical zones their shells come in many
different patterns and colors and are sometimes turned into jewelry they can grow as large as
nine inches and their bites can cause varying effects ranging from local inflammation to death
a teenager named jono from queensland australia nearly died after picking up a cone snail he
was on the hunt for textile shells and thought he had found one which was empty fortunately for him
he realized his mistake before the snail struck he turned the experience into a warning video for
others which has been viewed 17 million times so far number 7. stingray stingrays are cartilaginous
fish that are related to sharks just like their biological cousins they are some of the most
dangerous ocean predators they can usually be found within tropical and subtropical waters all
around the world their populations are dwindling leading them to gain an endangered classification
stingrays are flat with diamond-shaped bodies and indistinct heads male stingrays are about
two to three feet across while female sting rays can grow as large as four feet
stingrays are typically non-aggressive and tend to attack only when they are attacked because of how
flat they are they tend to get stepped on which is what causes a lot of human stingray injuries
stingray stings are typically non-fatal however this depends on the area of the body in which
the sting penetrates perhaps the most famous case of a stingray attack involves the wildlife expert
steve irwin the stinger penetrated his death and thoracic wall causing massive trauma the
entire thing was caught on camera terrifying fans the media governments and wildlife organizations
number six electric eel despite its name the electric eel isn't actually a true biological
eel instead they are fish that belong to a genus known as electrophorus and are known for their
ability to stun their prey using electricity the electric eel is slender in shape although they
are wider and flatter than snakes within they have three different organs which allow them to
generate an electric current these organs are made up of electrolytes which allows them to generate
low voltages or high voltages they are also air breathers they eat amphibians fishes and
crustaceans in 2016 a brazilian fisherman waded into a swamp in order to find an electric eel
sure enough the creature made an appearance and proceeded to attack the fishermen
however the fisherman was merely using himself as bait once the eel showed up he managed to kill
it before it could deliver a heart-stopping blow to him number five blue-ringed octopus
only four species of blue-ringed octopus exist however they are all very venomous they're found
in tide pools and coral reefs in the pacific and indian oceans from japan to australia
they have a distinct physical appearance consisting of yellow skin covered in blue
rings their diet typically includes crustaceans ranging from small crabs to shrimp to hermit crabs
blue ringed octopus are tiny ranging from five to eight inches in size they can change
shape and color pretty easily allowing them to hunt or hide as the need arises they produce a
powerful venom known as tetrodotoxin which can cause a variety of symptoms before resulting
in death they tend to stay calm in human hands unless they are mishandled a man by the name of
lance carlson was attacked by an octopus at the beach in western australia the octopus stung him
causing him to develop rashes all over his neck luckily he was able to obtain medical attention
before anything serious happened to him number 4. puffer fish puffer fish are some of the most
poisonous vertebrates in the world like the blue ringed octopus their skin tissues also contain
tetrodotoxins they grow as large as 20 inches and are typically found in the tropics even so there
have been rare sightings of them within temperate zones although they have been known to enter fresh
water they usually stick to brackish and marine waters because of the puffer fish's shape and size
it moves rather slowly through the water however they have a lot of defense mechanisms to protect
them from predators this is part of what makes them so dangerous the other part is that they are
considered a food delicacy and are relentlessly hunted to that end in the philippines three people
died after eating a puffer fish four others were sent to the hospital with severe illness
the tretorotoxin can cause all types of symptoms ranging from blurred vision stomach pain
shock heart palpitations and vomiting it takes an expert chef to know how best to prepare the fish
for consumption number three box jellyfish box jellyfish are beautiful invertebrates which
can produce potent venom delivered through their tentacles their stings can kill sea creatures and
humans as well causing massive pain before their victim's final breath they are quite fast capable
of moving as fast as 20 feet per minute their heads can also grow as large as 8 inches with
their tentacles extending beyond that reaching 10 feet in length box jellyfish are commonly regarded
as the most dangerous sea creature since australia began keeping records of these creatures in the
1800s 79 fatalities have been recorded the most recent fatality was the death of a 17 year old boy
occurring in february of 2021 it took an entire week for him to die during which he was plagued by
severe pain fever nausea and vomiting and blurred vision stings from boxed jellyfish lock the heart
and prevent it from beating it is the only thing in nature which kills
this way number two fire coral despite the name and appearance of these creatures they aren't
actually sea coral instead they are a species of hydra that has the appearance of seaweed because
they look so much like coral divers are usually deceived into thinking they are they can induce
a serious sting when touched upon contact an intense pain can be felt they can last from two
days to two weeks fire corals contain very tiny tentacles as well as a calcified external skeleton
that can scrape the skin fire corals are typically encountered off the florida coast in the caribbean
reefs and across the bermuda platform they are sessile creatures that can attach to rocks
coral seaweed or pilings divers are often warned about their appearance and their dangers first
aid treatment involves the application of seawater and vinegar number one great white
sharks the great white shark also called the white pointer is a creature whose reputation precedes it
in terms of geographical distribution the great white shark can be found in almost all coastal
and offshore waters which have water temperatures between 12 and 24 celsius however there are heavy
concentrations of this shark around the waters of the united states south africa japan oceania chile
and the mediterranean sea the great white shark has a physically imposing appearance
over the years the average size has gone down although it is still large enough to inspire fear
it has an average size of 11 tube 13 feet long although females are larger it also has a weight
ranging from 1151 pounds to 1700 pounds it also possesses counter shading which allows it to hunt
from above and below with ease it is an apex character in every sense of the word a man in
his late 20s was fatally mauled by one of these sharks off the coast of emerald beach australia
as the creatures tore his arm off he yelled out to witnesses for help
unfortunately help arrived for him too late he suffered significant injuries to his back and arm
would you rather cage dive with great white sharks or go on an expedition to see wild polar bears
