The pygmy rattlesnake is a small, venomous snake that lives in the southeastern United States. It is the smallest rattlesnake found on the North American continent. Its venom is strongly tissue-damaging, but the snake makes so little that a bite is unlikely to be fatal to an adult.1

Southeastern United States, from southern and eastern North Carolina south through peninsular Florida and west to East Texas and Oklahoma1

Lapeng
It lives in flatwoods, sandhills, longleaf pine savannahs, mixed scrub oak forests and floodplains, and is also found near lakes and marshes. It does not dig its own burrows. It uses holes dug by small rodents or gopher tortoises, and it prefers densely vegetated areas for cover.1

It eats small mammals, birds, lizards, insects, frogs and other snakes, and also giant desert centipedes. Young snakes lure skinks by waving the tail, while adults wait motionless in a coil for days at a time.1

Ho e tseba jwang

  • Small but bulky in width, usually 40 to 60 cm long including the tail1
  • Dorsal pattern of oval or roughly circular spots with somewhat regular edges1
  • Flank spots are mostly round and not much taller than they are wide1
  • Usually 23 rows of dorsal scales at midbody1
  • Young snakes may be paler or more vividly marked, and have a yellow tail tip. The rattle is tiny and gives only a faint buzz that is heard from a few feet away1

Chefo ya yona (eo e e kenyang ka ho loma kapa ho hlaba) e etsang?

Its venom is cytotoxic, which means it damages cells, and it is strongly haemorrhagic, which means it causes bleeding. The venom is tissue-toxic but contains no neurotoxins, which attack the nerves. The snake produces only a small amount of venom and contains substantial amounts of serotonin and related compounds.1

E kotsi hakae ho batho?

Kotsi ho batho: E bohlokoE ka utlwisa bohloko haholo, empa hoo e batlang e le kamehla ha e kotsi haholo.

The snake produces too little venom to be likely to deliver a fatal bite to a human adult.1

E etsang ha e tshohile?

Some individuals are very aggressive and strike furiously, while others are lethargic and do not rattle at all, and many are reluctant to bite.1

Dintlha

1

Its venom was the basis for the drug eptifibatide, which is used to prevent clotting during a heart attack.1

2

It is the smallest rattlesnake found on the North American continent.1

3

Its rattle is unusually small, which may show the early stages of how rattles evolved.1

4

Snake fungal disease has risen sharply in pygmy rattlesnakes over the past decade and is a major cause of death, though some snakes have recovered in the field.1

5

Females may give birth to live young even while infected with snake fungal disease.1

Ho senya ditshomo

Tshomo: Its bite is deadly to people.

Nnete: The snake makes so little venom that a bite is unlikely to be fatal to an adult human.1
