The notes I'm seeing is that the Oregon Spotted Frog is considered "Vulnerable" and not "Endangered". But it is a subcategory under Threatened. Other notes indicated that it is a "Candidate" for the Endangered Species List.

The frog has a relatively limited native range in the Cascades and various marshy lakes. A limited native distribution of any species puts it at an inherent risk to any changes that could change its competitiveness.

While Oregonians don't particularly hunt and eat frogs... The main problems are habitat loss, non-native predators, and increased competition.

The bullfrog is a non-native predator of the spotted frog. Human activities such as logging, or changing of wetlands and meadows into farmlands, or introducing non-native plants and other species could also affect their populations.

What does a goliath frog eat?

The Goliath Frog eats insects as well as smaller frogs.


Goliath is the name of the which biggest frog found on Earth?

The biggest kind of frog is the Goliath frog (Conraua goliath). They come from Cameroon in West Africa. Their bodies can reach the size of nearly a foot (30 cm) long. The Conraua Goliath weighs as much as a large housecat, about 3.3 kilos! Not to be confused with the Goliath Tree Frog. The Goliath tree frog is the largest of the tree frogs. They get to be a little bigger than golfball size. They are cousins of the viatnamese tree frog.


Worlds largest frog?

The Goliath frog (Conraua goliath) is the largest frog, it can reach a size of 17 to 32 centimeter (32 cm = 12,8 inch).


What is the bigest frog in the world?

The biggest frog in the world is aptly named the Goliath frog. It is native to a small region on Africa's west coast; Cameroon and Equatorial Guinea. Goliath frogs make their homes in fast moving rivers that flow through the rain forest. This frog's average length is 33 centimeters (13 inches) and weighs about 3 kilograms (6.6 pounds).Like many of its frog buddies, it is listed as "Vulnerable" by the International Union for the Conservation of Nature. The Goliath frog was hunted for food and for the pet trade. Now it is illegal to export more than 300 Goliath frogs per year, but they are so difficult to find that usually no more than 12 are exported yearly. The Goliath frog is also threatened with habitat loss as rain forests are cut down and rivers are dammed for electricity. Demand from collectors for these frogs has decreased, but at one time, they were sold for as much as $3000 to US collectors. Unfortunately, they don't breed well in captivity, so efforts need to be made to protect their habitat so that they can recover their population.


How does a Goliath frog attract a mate?

The Goliath frog is assumed to be the world's largest species of frog. The male typically builds a nest to attract a mate, but the males will also generally fight one another to win a mate's attention.
