How Many Different Types of Squirrel Are There?
Squirrels are members of the family Sciuridae. This group of animals includes a variety of medium-sized and small rodents, including flying squirrels, ground squirrels, and tree-dwelling species. All of these animals are native to North America and Eurasia. To answer the question “how many different types of squirrel are there?” it helps to first define the species.
289
There are 289 different types of squirrels, and they can all be found throughout the world. Of these, the United States alone has 65 species, including 8 species of flying squirrels. Some of the primary types of squirrels found in Tennessee include the Eastern Gray Squirrel, Red Squirrel, and Northern Flying Squirrel. You can also find some endemic species in other countries, such as Mexico.
Eastern gray squirrels, for example, choose a nearby tree as a refuge when a predator is close by. They avoid the distance involved in a flight by choosing a nearby tree. This is a practical survival strategy, as they avoid long and expensive flights, which can expose them to predators. The proximity of the threat can compromise the safety of the escape path. So, the shortest path to their nearest refuge is the most efficient one for squirrels.
Gray squirrels
How many different types of gray squirrels are in the world? Although the eastern gray squirrel is a native of the eastern United States, it has invaded other parts of the world, including Europe, where it has displaced the native red squirrel. Although the species is harmless, it is still considered an invasive species in parts of Europe. In addition to displacing the native red squirrel, it is causing habitat destruction in the areas where it lives.
Eastern grays can reach estrus as early as five months of age, but they are not fertile until they reach one year of age. Fertile males may induce ovulation in females during their estrus, and these females reach sexual maturity at between one and two years of age. Interestingly, female eastern grays have a reproductive life span of over eight and a half years in the wild, and males reach sexual maturity at two or three years of age.
Amazon dwarf squirrel
The Amazon dwarf is one of many species of squirrel. It lives primarily in the forest, where it lives in lowland areas and dense fog-covered forests. While the species prefers palm trees, it uses the entire forest, including rough vertical trunks, to live and forage. They can be approached within a short distance. But, be aware that the Amazon dwarf is also vulnerable to human trapping and hunting.
This small species is native to the Amazon rainforest and can be found in Peru, Brazil, Ecuador, and Colombia. Its body length is between 12 and 16 cm and tail is 8-16 cm long. It weighs between 86 and 132 g. The fur of the Amazon dwarf squirrel is reddish brown and tapers to a dull yellow on its underparts. Its ears are short and pale yellow, but do not protrude above the rim of its ear. It has no known breeding habits.
California ground squirrel
The first question to ask yourself is: How many different types of California ground squirrel are you likely to see? The California ground squirrel lives in burrows that are about four inches in diameter, although the entrances can be larger. The burrow systems of California ground squirrels are about five to thirty feet long, with most burrows found within two to three feet of the ground. The burrow systems can consist of single tunnels, a series of branching pathways, or they may be occupied by just one California ground squirrel.
The California ground squirrel is locally common and widespread throughout its range. No overall population estimate is available, but they are considered Least Concern on the IUCN Red List. Ground squirrels are highly beneficial to their habitat because their burrows create habitat for other animals, including snakes. They also help keep lawns and gardens clean by removing fallen leaves, twigs, and other vegetation. However, these rodents are often the focus of people’s efforts to keep them out.
Amazon flying squirrel
The Amazon flying squirrel is a unique species that resides in the tropical forests of the Amazon basin. It can grow to be over 40 inches long, including the tail, and weighs as little as 56 ounces. They are very agile, preferring to glide for short distances, and live in tropical forests. This species is found throughout Asia, ranging from southern China to northern Canada, Mexico, and North Carolina.
The red-tailed squirrel is a common sight in the southern and northern Amazon rainforests. Its coat is mostly red but can turn gray in the winter months. It is a common sight in the forested regions of Venezuela and Bolivia. The red squirrel tends to live on the ground, but it is able to climb trees. These squirrels are classified as least-concern species by the IUCN Red List.
Brazilian squirrel
The scientific name for the Brazilian squirrel is Sciurusaestuans ingrami. Its karyotype consists of 18 pairs of biarmed autosomes with a small, acrocentric X and Y in the interstitial regions. This squirrel also has four pairs of nucleolar organizer regions, or NORs, which are easily identifiable using silver-staining. The study also uses fluorescent in situ hybridization to determine if multiple NORs are present in the karyotype of the Brazilian squirrel.
Although the Brazilian squirrel is common in the U.S., its habitat is fragmented. Many populations have gone extinct because of ecosystem change, and some populations have become extinct. In fact, some populations have been completely lost in recent years due to habitat transformation. Because of this, the species is currently listed as a Species of Least Concern (SLC) but could fall into this category in the future.
