Grizzly Bears are derived from Brown Bears. They can reach a height of eight to nine feet tall, have a six inch tail, a shoulder height of three feet, and have an AVERAGE weight of 400-800lbs.
They're brown with white tips, a light color as a cub, and a rich, dark, chestnut when fully grown. They have huge lumps in their shoulder that help them dig, can store muscle, and act as great brakes when going downhill. Their long claws and teeth help them get animals, such as fish. They have thick skulls and a sense of smell which is world-renowned (1,000x better than ours, and can smell fish under water.) They can see at night, through rain, and the deepest fog.

Green Anacondas are the largest amongst them all; they can grow up to 29 (even 37) feet long! They can weigh up to 550 pounds! They don't use poison; rather, they constrict their prey and crush it to death. They hunt on land, but like the water, as they move faster in water.
The Anaconda's teeth are curved inward and are a huge factor in capturing prey. It can swallow Capybara and Jaguars! They can feed up to one animal for weeks... even months! It smells with its tongue, and has good camouflage. Ticks try to sorta eat the Anaconda, but glands emit a horrendous stench to ward them off.

Grizzlies' sense of smell is so good, they can smell a rotting carcass over two miles away! They eat things like moose, mountain goats, and maybe even other bears. Grizzlies are really fast runners and can dig extremely well. With winter, they will dig deep burrows and eat as much as they can before they hibernate, where they practically just sleep through all of it.
Mother Grizzlies reproduce between May and July, and they don't give birth until January to March, but must gain a lot more weight to carry on with the birthing.

Green Anacondas prefer wetlands, with vegetation and such, where it will lurk and wait to ambush its prey. It spends most of its life in the water. They're difficult to find; hiding in the deep forests of tropical South America. They're ambush hunters, so they wait around, and with deadly speed, they prance, constrict, and consume.
Female Anacondas (32.6Kg) mate with many males (mean 6.9Kg). Several males gather around females; one to 13. Mating seasons may last up to four weeks. The female doesn't feed during pregnancy, which is seven months long. They're also known to eat their smaller male counterparts when REALLY hungry...
Grizzlies have large front claws to dig, and to get a good grip on prey. They have large shoulder humps to decelerate down hills, and give extra digging power. They wade in water to catch fish.
The image above shows an Anaconda devouring a capybara. It will constrict its prey, takes about eight hours to consume, and can feed off this one animal for many months ahead.

Grizzly Bear cubs can stand on their hind legs, have thick fur like their parents, and will develop the muscular hump on their backs. Their claws and teeth are also inherited.

Green Anacondas take in their parents'
colors, teeth, eyes; all the basics. They
can slither around like others.
Grizzlies travel with their mother, who teaches them to hunt, which berries to eat, how to hibernate, and how to dig.
Klink, Oliver. Grizzly Bear Cubs. Digital image. National Geographic. N.p., 29 July 2009. Web. 07 Feb. 2014.
Green Anacondas learn ambush tactics, how to eat prey, how to constrict, and other hunting tactics. They'll learn how to deal with the months of no-eating (after eating a large animal) too.
If both animals were dropped into a ring, which one would defeat the other? The bear can claw and overpower the Anaconda, but the Anaconda could slither around and constrict the bear the death. However, neither animal could consume the other.

Deforestation is becoming a huge problem with both animals; as grizzlies flock in Alaska & Western Canada (coastal, arctic tundra, and interior forest), and the The Green Anaconda lives in the thick forests of South America (marshes, swamps, rivers...)

With this, numbers are dwindling.
Grizzlies are endangered, and Green Anacondas are NE (Not Evaluated.)
For Natural Selection to happen:
1) Grizzlies grow thick coats to thrive, if not hibernating.
2) They grow long claws and teeth to tear through meat.
3) They have large shoulder lumps to decelerate down a hill when catching prey.
4) They learn to waste less and to prepare for hibernation.
Male Grizzlies like to fight, and wild ones live up to 22 years, whilst females live up to 26. Captive one live to 44, and the longest known wild Grizzly was 36.
They eyes are also on top of its head, so it can see out
of the water without giving itself away (like a crocodile.)
Green Anacondas are the largest, heaviest, and second largest snake of the moment. Discovered by 1937.
For Natural Selection to occur:
1) They have become more stealthy and to ambush rather than to chase or pounce.
2) Anacondas have immense size to constrict their prey, as they don't have poison.
3) They learn to deal with lugging around a giant body in their stomach tract.
4) They consume victims large enough to fit their big ol' mouths..

Grizzlies have a skeletal structure like a dog's, and their teeth aren't as adept for shredding like dogs and wolves. They do, however, have sheer strength to make up for that. They've got short ribs, but their bones are so strong they've got amazing support.

This is a snake's skull. It's indeed very complex, but as you can see, it can swallow prey much larger and wider than its head due to its jaw formation.
This helps them survive so they can swallow large prey
and live off that one animal instead of constantly having to go out and kill another.

Their eyes and nostril placement allow them to see out of the water! They can sense heat from prey, and are known to eat things from birds, to pigs, to Capybaras, and even recently, Jaguars.
They can live up to 10 years in the wild, and 30 in captivity.
Poaching Green Anacondas are harder, and they're not really favored, so they are fine.
