Several scientists or scientific groups have made statements indicating they believe fish can experience pain. For example, in 2004, Chandroo et al. wrote "Anatomical, pharmacological and behavioural data suggest that affective states of pain, fear and stress are likely to be experienced by fish in similar ways as in tetrapods". [21]
The southern cricket frog has longer legs, with less webbing on the hind feet, and a more pointed snout, though northern cricket frogs have been observed with snouts indistinguishable from those of the southern species, [7] and the markings on the back of the thigh are typically more sharply defined than that of the northern cricket frog, [8 ...
They are sometimes known under the common name rain frogs. [1] [2] Formerly the subfamily Eleutherodactylinae of the family Leptodactylidae, it was raised to the family status following a major revision of New World direct-developing frogs in 2008. [1] [3] As currently defined, the family has more than 200 species (as of 2014, 206 [1] or 207 [2 ...
This is primarily due to their difference in predation methods. Goliath frogs are typically sit-and-wait predators. This means that they tend to capture/trap their prey either by luring them or using elements of surprise by acting extremely stealthy. As a result, they have a reduced metabolic rate and a unique method of breathing. When ...
Wood frogs experience very little of the winter because they are frozen solid for the coldest eight months of the year. This is a high-risk strategy! If ice crystals form inside their body, they ...
The family contains ranoid frogs that do not belong to any other families and are found on every continent but Antarctica. [4] The moor frog belongs to genus Rana, which includes species found in Europe and Asia. The moor frog is not found in the Americas. The moor frog's scientific name, Rana arvalis, means "frog of the fields". [5]
The frogs have been observed in primary forest and in secondary forest. When it is time to lay eggs, the frogs leave the forest and go to a swamp if they can. [3] The female frog makes a nest out of foam on a leaf. When the eggs hatch, they fall into the water below. [1]
Paleontologists have discovered a previously unknown ancient species: Kermitops — an amphibian that predates the dinosaurs and reveals the complexity of frog evolution. Researchers found a tiny ...
