Sharks!!!!!!!!!!!!!!JAWS!!!!!!!

Hey what's up today I'm going to talk about sharks. They they have a really bad reputation for being mean bad and evil because they bite peoples legs and arms off.. Well they do sometimes but it is very rare you guys should not be worried about anything because sharks only attack when they are violated or they are hungry. The main people who get bit by sharks are surfers because sharks confuse them for seals. They don't even like to eat humans they mite nibble you and swim away but like I said don't worry swim in groups and don't go to far out in the ocean when you swim and you will be fine.. Most people are scared of sharks because of this movie and book.

 This movie and this book made everybody scared of sharks and the people who saw the movie told other people and they got scared. What I'm trying to say is stay away from sharks but don't be scared of them :) 

Ok now I'm going to tell you about sharks. Sharks have gills just like any other fish they have perfect site perfect hearing and a perfect sense of smell. In clear water sharks can see there pray from 100 feet away. They can smell a little bit of blood from miles away.YEA WOW!!!. Sharks skin is covered in some sort of tooth like scales called (dermal denticales).  

Before I get into the shark I'm going to talk about I am going to tell you the three main sharks that you need to stay away from!!!! 1st we have the tiger shark , 2nd we have the Great white shark , 3rd we have the bull shark. The tiger shark has stripes going down his back. The great white shark is big and fat. The bull shark has a blunt snout and usually swims in shallow water. All sharks lay eggs and the reproduce sexually when they lay there eggs they either leave them or eat them.

I'm going to talk about one specific shark and that is the tiger shark and this is what it look's like.

They call him a tiger shark because of the things on him that look like stripes. This particular shark is very aggressive and this is one of the sharks that is dangerous if you mess with it SO JUST DON'T MESS WITH IT OK!!!!!!!!! This shark is common in the Atlantic ocean and the Gulf of Mexico. Tiger sharks are really fast swimmers they are known to travel far places in a short amount of time. The tiger shark is 1500 pounds WOW!! They can go up to 13 feet long they can swim up to 30, 35 miles per hour. They eat other sharks , crabs , turtles and fish. They  hunt at night like most sharks do. This is a really cool fact are you ready they can actually change color from green to blue. 


All sharks have a big perpose on earth and stay away from them but don't be scared of them. Just swim in groups and swim close to the shore and you will be fine!!!!!

Fish and what makes them fish!!!!

 Hey today I'm going to talk a little about fish and what makes them fish.. First of all you may think that fish live in water and that's all  well that is true but there is more to it than just where they live. The have gills and gills are like lungs but the let out water after the fish either swallows it or swims with its mouth opened. The fish  whole Circulatory system and when the water is done it comes out the gills.

FISH!!!!

 Some fish fish have scales and some have slimy skin and most fish are vertebrates witch means they have a backbone. The fish have scales because its easier for them to glide threw water another word for glide threw the water is streamlined and that means basically glide.


Another really cool fact about fish is that they sleep I bet you didn't think that they sleep well they do well not the same way as us. Fish don't have eye lids so when they sleep they stay still and their eyes stay opened. Do you see how the fish looks like he is swimming he is not he is asleep and his eyes are closed and he is just floating with the current.

Dolphins a mammal

All fish are cold blooded and  that means that they cant make there own heat as humans we can make our own heat. Some fish are mammals and some fish are not mammals if your a mammal you breath air so we breath air whales breath air and dolphins breath air.




When fish die they can either decnigrate or they turn in to fossils and a fossil is a rock that a fish died on or under and it molds the bones on the rock or fishes skin can just rot off and the bones are just lost in the ocean. 


 When fish die they become buoyant and that means that they rise to the surface because all of the air in the fishes body inflates and makes the fish rise to the surface.

This particular fish was washed up on the shore after it died and floated to the shore.


 Cartilaginous fish have cartilage and it is like bone but it is softer humans have bone here is an example of what a cartilaginous fish looks like

That was fish at the aquarium and it shows different kinds of fish I  think it is AWESOME. 






Lamprey fish are fish that are jaw less and they have teeth on the bottom of there mouth and they latch on to the things they eat and the     
teeth grind them and they eat them they look weird like this

This is the fish 

And this is what the bottom of him looks like
