The black-tailed rattlesnake is a venomous pit viper that lives in the south-west of the United States and in Mexico. It is known as one of the calmest rattlesnakes, and it relies on camouflage rather than confrontation.1

Anaishi

South-western United States (Arizona, New Mexico, west and central Texas) and Mexico south to Oaxaca, plus some Gulf of California islands1

Nyumbani

It lives in grasslands, desert areas, and rocky and mountainous areas, as well as high-altitude forests. It has been recorded at elevations up to 2930 m. It is a primarily ground-dwelling species, but it is an able climber and an expert swimmer.1

Jinsi ya kumtambua

Body colour ranges from yellows and olive greens to browns and black.1
The tail scales are entirely black, which gives the species its name.1
Often has a black band that runs across the eyes and down to the corners of the mouth, forming a facial 'mask'.1
Has a rattle made of keratin at the end of the tail.1

Nguvu ya sumu

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

Sumu yake hufanya nini?

Its venom is primarily hemotoxic, meaning it mainly acts on the blood and surrounding tissue, as with most crotalids (pit vipers). It is only about two-thirds as toxic as western diamondback venom. Because the venom is weaker, the snake has larger venom glands than most rattlesnakes in its region and injects large quantities into prey.1

Ana hatari gani kwa watu?

Hatari kwa watu: MbayaKuumwa kunahitaji daktari. Vifo ni nadra sana.

Bites are fairly rare, because the snake is considered one of the most docile rattlesnakes. The venom is generally not fatal to humans.1

Habari njema: madaktari wana dawa (ya kuzuia sumu) au matibabu ya hili.1

Hufanya nini akiogopa?

It normally tries to slither away when confronted, but it will rattle when cornered, and it relies mostly on camouflage to avoid discovery.1

Akiuma

CroFab antivenom is often used to treat bites from this snake.1
Mweke mtu bila kutikisika na mtulivu, weka kiungo kilichoumwa usawa wa moyo, ondoa pete na vitu vinavyobana, na umpeleke hospitali haraka.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Akikuuma: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

Its venom glands are larger than those of most rattlesnakes in its region, which compensates for its weaker venom.1

It is considered one of the most docile rattlesnakes because of its calm demeanour and curious nature.1

In the spring and fall it is mainly active during the day, but in summer it becomes nocturnal to avoid the heat.1

In winter it hibernates in dens made and abandoned by other animals, often sharing them with other snake species.1

Its lifespan averages 15 to 20 years.1

Kuvunja dhana potofu

Dhana potofu: The number of segments in a rattle shows how old a rattlesnake is.

Ukweli: Each time the snake sheds its skin, a new segment is added. Snakes can shed several times a year, and the rattle is fragile and can break, so its length is not an accurate guide to age unless the tip (terminal button) is intact.1
