What is a called blooded animal?

Cold Blooded Animal

Many animals such as fish, frogs, snakes and lizards are often called “cold-blooded,” as opposed to “warm-blooded” mammals and birds.

This does not mean their blood is always cold. Unlike warm-blooded animals, they do not have built-in temperature controls that keep their bodies evenly warmed.

Instead, their body temperature is usually near that of the surrounding air or water air or water.  The cold-blooded animal is hot in hot weather, and cold in cold weather.

Many depend on the sun for their body heat. Lizards, for example bask in the sun to warm their bodies.–Dick Rogers

How do crickets sing?

Cricket

Crickets chirp away merrily by rubbing their rough wings together.

The cheerful songs that crickets chirp have inspired the popular expression “as merry as a cricket.”  Actually, a cricket doesn’t “sing.”  A cricket fiddles its chirping note by rubbing its wings together.

The wing edges are rough where they overlap.  The chirping noise is produced by rubbing the rough edges briskly together.  In this manner, the boy cricket fiddles courtship songs to a girl cricket.

His chirps also serve to warn away enemies.  Crickets have keen ears, which are located on their legs instead of their heads.

The little pale-green tree cricket has the clearest and most musical notes of all.  It lives high in trees and bushes, and is sometimes called a “thermometer cricket” because of its ability to report the temperature.  It chirps faster as the temperature rises.

If you live where there are crickets, you can find the temperature by counting the member of chirps a cricket makes in 15 seconds and adding 39 to the number. – Dick Rogers
