Weasels belong to the group of mammals called mustelids that also include animals like badgers, ferrets, minks, polecats, wolverines, martens, and otters, collectively referred to as the weasel family. While weasels, including the least weasel, polecats, minks, ferrets and stoats are a part of the Mustela genus, the other members belong to separate genera. For instance, the wolverines form a part of the Gulo genus, while the otters come from the Lutra genus.

List of the Common Types of Weasel Species
In British English weasel refers to the least weasel of the Mustela genus, also known by other names like the common weasel, and little weasel. However, as per technical discourse, and even American usage, weasel includes all members of the Mustela genus, or rather the genus in totality.
Here the list of weasels have names of mammals that are a part of the Mustela genus including mink, ferret, polecat, and ermine.
The smallest species of the weasel is the least weasel, which ranges from 4.5 to 10 inches (11 to 26 cm), while larger species include long-tailed weasels or Egyptian weasels ranging from 10 to 12 inches (25 to 30 cm).
Weight: 3 to 12.3 ounces (85 to 350 g)
Body and Coloration: These animals have long and slender bodies with stubby legs. Sexual dimorphism exists, males being larger than their female counterparts. The tails range from 1.25 – 2 inches in length.
Weasels generally are black, brown, or gray with yellowish or white markings. They all become completely white during winter.

How long do they live
Most weasels live for an average of 3-5 years, though some live close to 10 years. The European polecat can live for 14 years.
What do they eat
As carnivores, their diet primarily consists of rodents like mice and voles. Weasels may also eat birds, their eggs, and young rabbits when these are unavailable. They are also known to raid chicken coops for eggs.

Behavior
They are primarily nocturnal animals, resting throughout the day, and coming out at night. However, evidence suggest diurnal behavior in weasels during the summer time.
Weasels are solitary, only coming in groups when mating and rearing young.
These mammals spend most of their waking hours hunting, as they need to eat to maintain their energy reserves constantly.
To kill prey, weasels bite down on their necks and apply pressure until death.
In order to keep warm, these creatures curl into balls inside their caves and lowering their metabolism.
Weasels will bob back and forth as a form of dance meant to intimidate their prey.
While they sometimes make their burrows, they can also take over other animals’ burrows or even termite hills.

What eats weasels
Weasels are hunted by birds of prey like owls, eagles, and hawks, foxes, snakes, and domestic pets like cats and dogs.
Adaptations
Most weasels can change the color of their fur by molting, allowing them to camouflage themselves better in their surroundings.
Their bodies are long and slender in shape, helping them enter their prey’s burrows quickly.
How do they reproduce
They are polygynous, with males mating with multiple females.

Life Cycle
After a gestation period that can vary from 35 days to 10 months, due to delayed implantation, a single litter of 3-12 kittens is born. Females single-handedly raise the offspring with no input from the father.
Sexual maturity is reached very quickly, with some like the least weasels capable of reproducing at 3 months.
As per the IUCN, most species of the weasel are “LC” or “Least Concern”.
