Finches need room to fly in their cages. The finch owner should make sure that the finch cage is large enough to allow the finches plenty of room for flying. A finch cage should be wider than it is tall and provide ample room for flying from one perch to another.
Snakes belong to the animal class reptiles. This group also includes crocodiles, lizards, and turtles. Reptiles are cold-blooded animals that raise their body temperature by lying in the sun or lower it by crawling into the shade. Their body temperature changes to the temperature of its surroundings.
Snake venoms vary dramatically from species to species, but they have one thing in common: Every one of them is an extremely complex composition, made from sometimes thousands of different proteins and enzymes, each with a specific function. Venoms can be roughly divided into three main groups: cytotoxins, neurotoxins and hemotoxins. But the lines dividing these groups are fluid, and most species employ a combination of the three. The type of poison and how fast it works is adapted to the snake's lifestyle and that of its prey. Sea snakes, for instance, have extremely fast-acting venom.
