T-rex

                                                       

                                T-Rex 

tyrannosaurus Rex ( or T-rex for short) is one of the most well-represented of large 
theropods. The T-rex was known as ''the king of the dinosaurs'', and was found in a 
variety of rock formations dating the maastrichtian age to the cretaceous period, and
was one of the last dinosaurs before the Cretaceous-paleogene extinction event. 


1.Description:
The T-rex was one of the largest land animals of all time; the largest t-rex 
ever found was Lucy, which measured 12.3 meters ( 40 ft) long, and
 was 4 meters ( 13 ft) long at hips.The T-Rex's neck formed a natural 
S-shape curve like other theropods, the forelimbs had only two claws,
T-rex bite could destroy bone wih only on bite. 
                                                   
   










2. feathers:
Their is a theory that the T-Rex might have feathers in its body, one scientist 
said that even lucy had some sort of hair in her body, another T-rex called 
Dilong paradoxus , found in china, had some kind of feathers. The trex may 
had feathers when it hacthed from its egg, as it grew it may had shed its
feathers. 


3.Prey: 
The T-rex heavily prey on the triceratops because some can be old and sick 
which can be an easy prey and also eat edmontosaurus, alamosurus, 
denvesaurus, and even cannibalism its bite force was overpassed by 
the megalodon and the giant croc and some studies found bones of a trex 
with bites suggesting it was attacked by the same species. 


4. Arms: 
Scientists have been very confused at the dinosaur's claws, 
which measure about 1 meter (3.3 ft), it may had use to hold
a prey and give it a chance to kill it easier, or to hold a mate during mating. 



5. In popular culture: 
The T-rex is one of the most popular and well recognized animal of all time,
its featured in movies such as Jurrassic Park or King Kong and in
video games, books, television, cards, and stamps.

Loggerhead sea turtle

                                           
                                     
                                         Loggerhead sea turtle 
            
The Loggerhead sea turtle is an oceanic turtle distributed around the world. It is currently 
 vulnerable, do to being hunted for their eggs and meat and because they eat plastics or 
 bottles that kill it.  It is a marine reptile, belonging to the family cheloniidae, and its one of
 the most interesting animals in the ocean. 

 1. Description: 
The Loggerhead turtle is the world's largest hard-shelled turtle. Adults weighed more 
than 80 pounds to 200 kg ( 180 to 440 lb) and the head and upper shell are range from yellow to orange, while the underside is plain pail yellow. The shell serves as an external armor,although  loggerhead turtles cannot retract their head or flippers into their 
shells, the lachrymal glands  located behind each eye allowing the loggerhead 
to maintain osmotic balance. 

2. Habitat:
The loggerhead turtle spend most of its time in the open sea and in shallow coastal waters, they rarely come ashore, except for the female's brief visits to construct nests and deposit eggs. Hatchling loggerhead turtles live in floating mats of sargassum algae. Loggerheads like water that is 13.3-28.0 C ( 56-82 F), and tons of small animals or algae are grow on the turtles shell. 


3.Feeding: 
The loggerhead turtle is omnivorous, feeding mainly on bottom-dwelling invertebrates, 
such as gastropods, bivalves, and decapods. They are likely to eat sponges, corals, 
sea pens, isopods, insects, barnacles, sand dollars, and squids. They crush their 
prey with powerful jaws and use some points called the ''pseudo-claws'' to tear l
arge pieces of food in the loggerhead and acid inside the turtle increases as 
temperature increases. 
                         










4. Predators:
The loggerhead turtle does have alot of predators, especially early as they hatch from 
their eggs. Some predators are the ghost crabs, beetles, fly larvae, ants, parasitiod 
wasp larvae, flesh flies, snakes, toads, and even seabirds. When they are fully 
grown they might be attacked by sharks, killer whales, humans, feral dogs,
 and flesh flies. 


5. diseases: 
Dangerous bacteria such as pseudomonas and salmonella attack loggerhead hatchlings 
and eggs.fungi such as penicillium can cause external tumors, which the tumors interupt 
the turtles behavior or can cause blindness.Can cause lesions in the turtles lungs, 
heart,and intestines. 



6. conclusion: 
People have been trying to safe the turtles as they are been captured by seamen in fishing nets or stopping people from selling them illegally, the turtles are proctected by the nature conservation act of 1992 and volunteers looks from nests and takes care of the turtles eggs and when they hatch, some are free and others that died are taken to laboratories to study them, but its important to not capture them.
