that propels the jumper away from the substrate. Any solid or liquid capable of producing an opposing force can serve as a substrate‚ including ground or water. Examples of the latter include dolphins performing traveling jumps‚ and Indian skitter frogs executing standing jumps from water. Jumping organisms are rarely subject to significant aerodynamic forces and‚ as a result‚ their jumps are governed by the basic physical laws of ballistic trajectories. Consequently‚ while a bird may jump into the

Organisms as small and seemingly harmless as the Cuban tree frog have had a larger impact than one would think on not only native amphibians‚ but many native insects and reptiles too.

Unfortunately‚ due to their gluttonous nature‚ Cuban tree frogs often nearly wipe out local

The daddy frog was called a bullfrog And how he croaked and how the mammy frog Laid hundreds of little eggs and this was Frogspawn. You could tell the weather by frogs too For they were yellow in the sun and brown In rain. Then one hot day when fields were rank With cowdung in the grass the angry frogs Invaded the flax-dam; I ducked through hedges To a coarse croaking that I had not heard Before. The air was thick with a bass chorus. Right down the dam gross-bellied frogs were cocked

We are a noisy lot‚ that is what our teachers say about us. This is largely due to Ah Keong. He is the noisiest of us all. His voice is like that of a bull frog but volumes louder. It seems that he cannot talk softly. Actually he does not talk‚ he shouts. Perhaps his living with his family of ten children has something to do with it. In this noisy bunch lives a boy who hardly ever opens his mouth. This is Padma‚ the boy who sits next to me. He is such a gentle and soft creature that one would think

where the troop of trees stood‚ practically hugging each other. I enjoyed watching the giant trees sway with each other as if they were moving towards nature’s music. On my side of the lake‚ there was a choir of frogs chattering and birds chirping. I sang a little melody too‚ but the frogs and birds suddenly stopped‚ they must have disliked my tune. As I was about to rest my eyes a little‚ nature woke me up. The calming breeze tickled my ear lobes and I could faintly hear it whispering secrets to
