  Dolphins is one of my favorite organism,  Dolphins are highly intelligent marine mammals and are part of the family of toothed whales that includes orcas and pilot whales.I love dolphins so much this summer i’m going to the aquarium to see and play with the dolphins.
Dolphins are classified has the following:

Domain: Eukarya
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia]
Order: Cetacea
Family: Delphinidea-
Genus: Delphinus
Species:T. truncatus
                                                 Dolphins

While doing my researchon dolphins  I found an evolutionary tree . This evolutionary tree shows the evolutionary relationship.


Did youknow?  To prevent drowning while sleeping only half of a dolphin brain goes to sleep the other half stay awake so it can breathe.



I hypothesis that dolphins have strong teeth they are carnivores, mostly eating fish and squid. if dolphins didn’t have strong teeth they would not be able to chew squid because squids have hard tentacles with sharp nails looking object.
 Bottlenose dolphins not only have individual “names,” technically signature whistles they use to identify themselves, but they also copy the whistles of companions and family members likely as a means of calling out to those specific animals just like humans call each other by their  name.  Both humans and dolphins are  mammals, so both have mammary glands, and hair on their skin, and they have 7 cervical vertebrae as humans do.Both are mammals, so both have mammary glands, and hair on their skin, and they have 7 cervical vertebrae as humans do. Dolphins have bigger brain than humans. This piece of information is form Take Part and Answers.

 I predict that dolphins  might not live for  a long time due to  the slaughter of more than 20,000 dolphins and porpoises off the coast of Japan every year, and how their meat, containing toxic levels of mercury, is sold as food in Japan and other parts of Asia, often labeled as whale meat, the hunt still goes on find out what you can do to help these poor dolphins.  The majority of the world is not aware this is happening.

CLASSIFICATION LEVEL OF A PANDA BEAR

CLASSIFICATION LEVEL OF A PANDA BEAR
Kingdom- Animalia- Multicellular and needs oxygen
Phylum- Chordata- Symmetrical with distinct heads. at one point of development, they posses backbones or axis.
Class- Mammalia- All mammals have hair and are able to regulate their body temperature and their females can produce milk.  
Order- Carnivores- Not all carnivores eat meat, like pandas mostly eat bamboo sticks, strong limbs and acute sense.
Family- Ursidae- Members of the bear family, have 5 toes on each feet and some can walk upright for a short distance.
Genus- Ailuropoda
Species- Melanoleuca-  Giant panda is the only member of the genus ailuropoda because it is not very closely related to any other bears.
http://nationalzoo.si.edu/animals/giantpandas/pandasforkids/classification/classification.htmThe Panda bear is an endangered species preyed on by jackals, leopards, and yellow throated marten, they prey on bamboos which are the producers. It takes pandas 90 to 160 days to reproduce and although the most often give birth to twins, the reproduction rate is one young panda every 2years. Fossils have been found over the years and its skin/ physical appearance shows its relation to other bears which means a giant panda bear possibly evolved from a normal bear.http://wwf.panda.org/what_we_do/endangered_species/giant_panda/solutions/pandasuccess/
Natural selection affected the physical appearance of a panda because the black circles fur on its eye was an evolution to make them look ferocious to predators. A Panda is different from others in its community because it is the only animal in its species and its the only one classified as carnivores but eats mostly short trees and bamboo sticks. Panda is an endangered species and looses its population often but i predict an increase in population because of  the reservations being made for its protection from extinction and it doesn’t have a lot of predators

Golden Snub Nose Monkey - By Yazmine Garay

   
Monkeys are one of my favorite animals, but with the Golden Snub Nose Monkey catches my eye because of it very different face which it blue and because of its golden redish fur.


Domain - Eukaryte
Kingdom -  Animalia
Phylum -  Chordata
Class -  Mammalia
Order -  Primates
Family -  Cercopithecidae
Genus  -  Rhinopithecus





These are fossils are of the Golden Snub Nosed Monkey. These fossil can be compare to the Old World Monkeys fossils.


FUN FACTS !

Bald Eagle By. Brandon Newton



Scientific Classification:


Domain:Eukaryota
Kingdom-Animalia
Phylum-Chordata
Class-Aves
Order-Falconiformes
Family-Accipitridae
Genus Species- Haliaeetus (Sea Eagle) Leucocephalus (White Head)



Fun Fact: Bald Eagles have a wingspan of 7 feet on average and they can live 28 years in the wild and 36 years in capacity!


Natural Selection Trait for a Bald Eagle: One trait a bald eagle has resulting from natural selection is the curved and very sharp talons and The soles of its feet have raised, rough projectiles that also help hold its prey firmly in place. Bald eagles usually live near lakes or bodies of water so they need these features on its feet to catch fish successfully.


What Organisms are similar to the Bald Eagle in its environment?: Bald eagles diets are very similar to the black and brown bears, they all rely on the bodies of water to be in the area because they primarily prey on fish.


What Organisms are different from the Bald eagle in its environment?: An animal that is very different from the bald eagle in its environment is the beaver, not only do they rely on the water for home and food but they live there while the eagle just uses it as a food source.


What would happen to my animal over time if drought spread over all major lakes?: My animals population would drop drastically, the lakes would dry up and fishes would die and decompose. This would also mean over any body of water that did not dry up Eagles would compete for food and then it really becomes survival of the fittest.




The Siberian tiger
By Alexus Simpson




The different classifications of my species are. felinae,pantherinae,and acinony china .one fun fact about the siberian tiger is that it can eat up to one hundred pounds of meats a night.This is like a human eating up to a total of four hundred burgers.The siberian tiger needs a lot of food because they eat between days.The organisms which my species of siberian tigers evolved from is cats.All the modern cats developed about 10.8 million years ago in south asia.I believe the siberian tiger has stripes to survive in the wilderness.the siberian tiger has stripes to camouflage itself from its pray .The siberian tiger is similar to regular house cats its just larger in size and more agressive.The siberian tiger is different from other tigers because they have a different pattern of stripes and the siberian tiger has a main.I predict that siberian tigers will soon die out.I believe this will happen because they have to eat a hundred pounds of meat to fill them up.If they continue to eat everything in their environment the other animals will eventually not be able to reproduce.These are some important facts about the siberian tiger.

Example




 Loggerhead Sea Turtles
One of my most favorite organisms is the loggerhead sea turtle (Cartetta caretta). The loggerhead sea turtle is an endangered marine turtle species. Last summer, I found a baby loggerhead sea turtle in the bushes and I returned it to the ocean. I like to think that it survived the ordeal and is growing healthy and strong.

The loggerhead sea turtle is classified as follows:
Domain: Eukarya
Kingdom:  Animalia
Phylum: Chordata
Class: Reptilia
Order: Testidunes
Family: Cheloniidae
Genus: Caretta
Species: caretta



Through my research I found an evolutionary tree that suggested to me that the Chelonia mydas (Green sea turtle) may be the loggerhead sea turtle’s closest evolutionary relative. The evolutionary tree below shows the evolutionary relationshipPhylogenetic Tree: Chelonia mydas      Created by: Melissa Martinelli




According to DNA evidence the loggerhead sea turtle is also related to the ridley and hawksbill turtle. According to Chapter 1, What is a Loggerhead Turtle? A Genetic Perspective by Brian W. Bowen, “ from a phylogenetic perspective, this is an animal that diverged from the ridley and hawksbill turtles on the order of 10 million years ago, indicating a long history of independent evolution and adaptation.”

The loggerhead sea turtle has no teeth but they do have a powerful jaw.  I hypothesis that the loggerhead sea turtle has a powerful jaw because its diet includes animals with shells (crabs, mollusks, shrimp and horseshoe crabs). Without the powerful jaws the turtle may not be able to break through the shells and get the food that they need to survive.

The loggerhead sea turtle lives in coastal waters. They share this environment with lobsters. Lobsters are similar to loggerhead sea turtles because they both need to consume food to get nutrients. Unfortunately for some lobsters, loggerhead turtles eat them (click link below for a video of the loggerhead eating a spinny lobster.) Also on the link you can find fun facts about loggerhead sea turtles. Did you know that loggerhead sea turtles can reach 253 lbs, or that they can travel up to 15 miles per hour?


Another favorite marine organisms of mine is the Florida Manatee (T.m. latirotris). The Florida Manatee is in the same phylum as the loggerhead sea turtle, phylum: chordata. Organisms in the phylum chordata have a complete digestive system. This means that despite the differences in their diets, the loggerhead sea turtle and the manatee digest their food the same way (just like us humans – we are in the phylum chordata too).

The diet of the loggerhead turtle not only consists of hard shelled organisms, but also of shrimp, soft jellyfish and seaweed. If there was a dramatic change in temperature in the upper layer of the ocean, a change that decreased the turtle’s softer food sources, the loggerhead would be forced to eat primarily the harder shelled organisms that live on the bottom of the ocean where the temperature might not changed as much. If this temperature change affects the turtles food supply for a long period of time, one evolutionary change that may occur is that future loggerhead turtle may have an even stronger jaw and possibly teeth.
