Safety in numbers. You can normally trust a member of your own species not to attack you, and if they are standing next to you then any predator in the area may choose to attack them instead of you.

About 250000 of them have been found.
Species diversity :)
The Chinese river dolphin is an extinct species - A living individual cannot be found in this species anywhere in the world.
Both the criollo (people of Spanish descent, born in the Americas) as well as the rather extensive indian populations found in Mexico.
The clumps of growth are called colonies.
Every species of cockatoo has it's own natural habitat, depending on the country where the species occurs. No species is alike, and even populations of the same species can live in slightly different habitats. The Australian cockatoo species generally live in very large groups and stay in the open field a lot, while the other species generally live in smaller groups and spend more time in the canopy.The cockatoo species that are living Indonesia live in tropical or subtropical forests or on the edges of these forests. These species are for example the Umbrella Cockatoo and the Moluccan Cockatoo. Species from Australia are mostly seen in open fields and only use trees to nest and sleep in.Food will be collected on the ground and in the trees. Nuts and seeds will be found on the ground, while fruit, leaves, buds and insects will be obtained from the trees. The Australian species of cockatoo are mainly depended on food they find on the ground. These Australian species also generally forage in large groups, so many cockatoos will watch out for the safety of the group while they are in a vulnerable position on the ground.
There are seven species of frog found in New Zealand, three of which are non-native species introduced by settlers. An additional five species were introduced in the 1800's that were unable to establish successful populations. None of these are present today. All of the native species and two of the introduced species are listed as threatened or endangered.
No. It seems to be found in most groups equality. Since it is found on the X chromosome, males have one copy. Females have two copies. Since it is found on the X, females have a "good" gene that sort of covers the defective one. Males don't have that chance. So many more males have this than females.
Bacteria found in groups called biofilms are found on the teeth. Upward of 300 different species of bacteria can inhabit the biofilms that form dental plaque.
As a full species, the gray wolf is not an endangered species. However, certain local populations are declining or are endangered. The gray wolf, in spite of persecution by humans, still has a large range, being the only wild canine found in both Eurasia and North America.
What types of populations can be found in the temperate forest. Think of the different types of populations and species that live in that area. Then, see how they connect together. Example: A cheetah and elk; a cheetah eats the elk Think of more to add to that list. What does the elk eat? What eats a cheetah? http://biology.about.com/od/landbiomes/a/aa052506a.htm
Crotalus stejnegeri is a rattlesnake species found in western Mexico. It is not listed as endangered but is a threatened (vulnerable) species due to habitat fragmentation and loss.
No. No species of bear is endangered in the U.S. The bears found there, the brown and black bears, are listed as least concern, and the polar bear is listed as vulnerable. Some local populations may be under threat, but as full species, none are endangered.
