A r\u00e3 mais pequena do Mundo caberia num dedal!<\/p>\n
A que dist\u00e2ncia pode saltar uma r\u00e3?<\/p>\n
O recorde do salto de uma r\u00e3 \u00e9 de 5 metros e 30 cm.<\/p>\n
H\u00e1 muita gente que gosta de comer pernas de r\u00e3, guisando-as com manteiga. Diversos restaurantes contam com pernas de r\u00e3 no seu menu, pelo que se chegou a fazer cria\u00e7\u00f5es em quintas apenas com esse prop\u00f3sito.<\/p>\n
O que comem as r\u00e3s?<\/p>\n
Felizmente para n\u00f3s, as r\u00e3s comem mosquitos, moscas, tra\u00e7as, baratas, peixinhos pequenos e larvas. As r\u00e3s t\u00eam a boca muito grande e t\u00eam duas filas de dentes na parte superior e nenhuma na inferior. Tamb\u00e9m t\u00eam uma l\u00edngua longa e viscosa ligada \u00e0 parte dianteira da boca, n\u00e3o \u00e0 de tr\u00e1s, como sucede com a maioria dos outros animais, incluindo n\u00f3s. Pode projectar essa l\u00edngua a uma grande velocidade, para apanhar as presas de surpresa.<\/p>\n
O que \u00e9 um girino?<\/p>\n
Um girino \u00e9 o beb\u00e9 das r\u00e3s ou dos sapos, mas tem mais o aspecto de um peixe que de outra coisa. N\u00e3o tem patas e a sua cauda \u00e9 muito longa, respirando atrav\u00e9s de guelras.<\/p>\n
Onde vai parar a cauda quando um girino se transforma em r\u00e3?<\/p>\n
Quando o girino se transforma em r\u00e3, a sua cauda torna-se mais e mais pequena, mas n\u00e3o desaparece, muda e vai-se integrando no resto do corpo. Durante esse tempo, crescem patas ao girino e as guelras transformam-se em pulm\u00f5es.<\/p>\n
Qual \u00e9 a maior r\u00e3 do Mundo?<\/p>\n
A maior r\u00e3 \u00e9 a r\u00e3 Golias que vive na \u00c1frica Ocidental. O maior exemplo que j\u00e1 foi capturado pesava quase quatro quilos e media 80 cent\u00edmetros, com as patas esticadas.<\/p>\n","protected":false},"excerpt":{"rendered":"
