Hey guys it's Kerry lots of my favorite sea animals today
sit back and relax and watch the sea animals swimming by
whale shark they are a highly migratory pelagic
species distributed throughout the world's tropical seas
these giant sea planktivores are usually found in coastal zones with high food
productivity whale sharks are solitary and are strong
but slow swimmers

hermit crab they have adapted to occupy empty
scavenged mollusk shells to protect their fragile exoskeletons
thresher shark these clever sharks use their unique
long tails to stun and catch prey fish have no chance if a thresher shark
enters its path
pufferfish they can inflate into a ball shape to
evade predators they fill their elastic stomachs with huge amounts of water and
sometimes air some dangerous sea animals to look out
for are the puffer fish that you've just seen
the venomous lionfish sea snakes
a single bite can be fatal tiger shark and great white shark they
can tear out chunks of flesh with their specially designed teeth
box jellyfish they have tiny darts that are loaded with poison
once stung by them humans and animals can experience cardiac arrest paralysis
or even death
octopus this siphon is used both for respiration
and for locomotion by expelling a jet of water
they have a complex nervous system and excellent sight and are among the most
intelligent and behaviorally diverse of all invertebrates
piranha they have a single row of sharp teeth in both jaws the teeth are tightly
packed and interlocking lobster
their two potent claws allow these predators to eat a lot of different prey
such as small fish sea urchins crabs and sea stars
when lobsters lose a claw a new one grows up with the next molt
blue whale they reproduce via sexual meiosis
the male and female each produce haploid gametes
male gametes are sperm and the female gametes are eggs
a single sperm and egg fertilize to form a diploid zygote
they fertilize internally meaning sperm is deposited inside the female
this usually happens after a very elaborate mating ritual
the male and female spend time rolling around each other then they take a deep
dive into the ocean and as they continue to communicate with each other they
suddenly fly upwards and cross the surface
and as they do the male deposits the sperm inside the
female females have a long vulva with two nipples on each side to nourish
newborns hammerhead shark
this cephalofoil has many functions including sensory reception
maneuvering and prey manipulation the cephalofoil gives the shark superior
binocular vision and depth perception they are found worldwide in warmer
waters along coastlines and continental shelves
bonnet head shark is a type of hammerhead shark with a
smooth rounded head
it has small sharp teeth in the front of the mouth for grabbing small fish and
flat broad molars in the back for crushing crustaceans and mollusks
pilot whale they are notorious for stranding
themselves on beaches but the reason behind this is not fully understood
they have an anchor shaped patch under the chin
their long sickle shaped flippers and tail stocks are flattened from side to
side
blue crab males are bright blue in color with
white spots and characteristically long chelipads
blue spotted ray these rays like to bury themselves just
underneath the sand where they will feed on various invertebrates
reef squid some species are able to propel
themselves out of the water they expel the water in their mantle as a type of
propulsion to get airborne
like other cephalopods it has a strong beak which it uses to cut the prey into
parts so that the raspy tongue or radula can be used to further process the food
it consumes small fish other mollusks and crustaceans
they are capable of rapid changes in skin colour and pattern for camouflage
and courtship rituals
bowhead whale they have a thick layer of blubber that
protects them from the freezing cold Arctic waters
main predators of bowhead whales are killer whales
they can stay 40 minutes under the water without returning to the surface to
breathe
beluga there is no dorsal fin which allows it
to swim under ice with ease it possesses a distinctive protuberance
at the front of its head which houses an echolocation organ
plesiosuchus had a different shaped skull
with a longer shallower snout it's specialized in eating other marine
reptiles they roamed the seas
150 million years ago their skull could grow to 1.2 metres
mako shark are a large fast-moving oceanic shark with a deep blue back and
white underparts there are two living species the short
fin and the long fin mako
Dunkleosteus is an extinct genus of large armored jawed fishes that live during the late
Devonian period
it could quickly open and close its jaw like modern day suction feeders
and had a bite force of 1200 pounds per square inch
it was one of the largest placoderms to have ever existed
it's two-part bony armored exterior made it a relatively slow but powerful
swimmer instead of teeth
dunkleosteus possessed two pairs of sharp bony plates which formed a
beak-like structure
sperm whale they are the world's largest tooth whale
and unlike the baleen whale they are active predators eating large squid
bony fish and sharks their teeth are conical shaped for
catching prey they have a large brain and the most
powerful sonar which they use to help find prey in the dark deep seas
pygmy sperm whale are small robust whales with a distinctive underslung jaw
not unlike sharks they have the shortest rostrum among cetaceans
mosasaurus had a fully aquatic lifestyle it had a streamlined body an elongated
tail ending with a downturn supporting a two-lobed fin and two pairs of
flippers
it looked much like a sea going lizard
megaloden is a prehistoric monster shark that
first appeared about 20 million years ago
it is the largest prehistoric shark to have ever existed and one of the most
powerful predators on earth its teeth grew up to 16 centimeters long
and it would have fed on large prehistoric whales
as teeth are lost broken or worn down they are replaced by new teeth
great white shark is an epipelagic fish found where there is an abundance of
seals sea lion cetaceans sharks and fish
bull shark it is known for its aggressive nature
and presence in warm shallow brackish and freshwater systems including
estuaries and rivers they thrive in both salt and fresh water
and can travel far up rivers humpback whale
humpbacks feed in polar waters and migrate to tropical or subtropical
waters to breed and give birth fasting and living off their fat
reserves
kronosaurus is an extinct genus of short necked pliosaur
its teeth grew between 7 and 30 centimeters
the combination of large size conical shape and lack of cutting edge allows
for easy identification of its teeth
