What Do You Know About The Nelson's Small-eared Shrew Quiz

Explanation
Edward William Nelson and Edward Alphonso Goldman were both renowned American naturalists and explorers who made significant contributions to the field of biology in the late 19th and early 20th centuries. They conducted numerous expeditions and discovered several new species during their careers. Therefore, it is plausible that they could have been the ones to first discover the species mentioned in the question. However, there is no information given about San Martin, so it cannot be determined whether they were involved in the discovery or not.

Explanation
The correct answer is Cryptotis nelsoni. This is the scientific name of the 1894 mammal species mentioned in the question.

Explanation
The given question is asking for the genus of an organism that belongs to the kingdom Animalia and class Mammalia. Among the options provided, "Cryptotis" is the only one that represents a valid genus name. Therefore, "Cryptotis" is the correct answer.

Explanation
The question states that the species in question was believed to be extinct, but research conducted revealed that they still exist. This implies that the research was conducted after the species was thought to be extinct. Among the given options, the only year that comes after the species was believed to be extinct is 2003. Therefore, the correct answer is 2003.

Explanation
The explorers discovered that the species they were studying was facing pressure from various human activities. Logging, cattle grazing, induced fires, and agriculture were all identified as factors contributing to the species' decline. These activities directly impact the species' habitat and food sources, leading to a decrease in their population.

Explanation
Cryptotis nelson is a species of small mammal. The given answer, 55-100mm, suggests that the head and body length of Cryptotis nelson is typically between 55mm and 100mm. This range indicates the average size of this species, providing a reference for understanding its physical characteristics.

Explanation
The correct answer is C. Mexicana because the question states that the shrew has sooty brown fur that is darker than that of the related species. This implies that there is a related species with lighter brown fur, and C. Mexicana is the only option provided that fits this description.

Explanation
The correct answer is "Day and Night" because the statement mentions that they have a voracious appetite and eat very frequently, which implies that they are active throughout both day and night.

Explanation
The animal was last seen 109 years ago, which would place the sighting in the year 2003. This suggests that the animal was thought to have gone extinct prior to 2003, and then was seen again in that year.

Explanation
In 2004, the team of zoologists set off for San Martin Tuxtla volcano to find this animal.
