Greening's frog is a small tree frog that lives in the dry thorn scrub of eastern Brazil. It is venomous: it has spines on its skull that can inject venom when it headbutts. It is special because it survives a semi-desert climate by hiding in tree hollows, rock cracks and bromeliads.1

Siyatyhefa okanye sinetyhefu? Izilwanyana ezinetyhefu zitofa ityhefu ngokuluma okanye ngokuhlaba. Izilwanyana ezityhefayo ziyingozi xa uzichukumisa okanye uzitya. Esi siyatyhefa.

Sihlala

Ekhaya

It lives in the caatinga, a semi-desert of shrubland and thorn forest with a short wet season and a long hot dry season. It is usually found on plants, including bromeliads, and on rock outcrops. It breeds in temporary streams.1

Amava anetyhefu

Amava abukhali aphethe ityhefu. Ukusinyathela okanye ukusibamba kubuhlungu.

Ityhefu yaso yokuluma okanye yokuhlaba yenza ntoni?

Its skull spines inject venom into other animals, or into a human hand, when it headbutts. Its skin secretions contain steroids and alkaloids, which in laboratory tests caused a powerful painful effect and swelling in mouse cells. In the wild these secretions act as a chemical defence against predators.1

Siyingozi kangakanani ebantwini?

Ingozi ebantwini: KubuhlunguKunokuba buhlungu ngokwenene, kodwa phantse akusoze kube kubi kakhulu.

Senza ntoni xa soyika?

It hides in a tree hollow, rock crevice or bromeliad, sealing the entrance with its head, and it defends itself by headbutting with its skull spines.1

Ukuba amava aso ayakugwaza

Ukuba umntu usichukumisile: hlamba izandla kakuhle kwaye ungachukumisi amehlo okanye umlomo. Ukuba umntwana okanye isilwanyana sasekhaya sisikhothile okanye sisityile: tsalela iziko lezityhefu okanye inombolo kaxakeka.

Soloko utsalela inombolo kaxakeka kuqala (112, 000, 911). Esi sisikhokelo soncedo lokuqala ngokubanzi, asilocebiso lwezonyango. Iziseko zoncedo lokuqala

Hlala ukhuselekile

Ungaze uchukumise, ubambe okanye uqhule isilwanyana sasendle, nokuba sincinci, kwaye nokuba sibonakala silele okanye sifile.
Sinike indawo. Ukuba udibana naso, hlala uzolile, buyela umva kancinci kwaye usiyeke sihambe ngendlela yaso.
Ukuba amava aso ayakugwaza: hlala uzolile, musa ukushukuma, tsalela inombolo kaxakeka (112, 000, 911) okanye uye esibhedlele ngokukhawuleza. Khumbula ukuba sasikhangeleka njani, ifoto iyanceda.

Asikuzingeli. Sisebenzisa ityhefu yaso ukubamba ukutya okanye ukuzikhusela, kwaye singakhetha ukuzimela. Okungakumbi malunga nokuhlala ukhuselekile

Iinyaniso

Unlike poison dart frogs, which only secrete poison from their skin, this frog can inject venom through spines on its skull.1

The skin of its head is fused to the skull to form a casque, a hard helmet-like structure.1

In laboratory tests, its skin secretions also slowed the growth of mouse fibroblast and melanoma cells.1

It has a tough, water-resistant skin and a low metabolic rate, which help it survive the dry semi-desert climate.1

When the rains start and the streams run with water, males set up territories near the water and call to attract females.1

It shares its headbutting, spine-injecting defence with another frog, Nyctimantis brunoi.1
