There are many fascinating animals, mammals or otherwise, that have names beginning with the letter ‘g’. Some of the most popular ones include:

Most animals cannot get to this same vegetation, especially herbivores. Despite its length, the giraffe’s neck has the same number of bones as other hoofed mammals, only that the bones are much longer.

To complement its long neck, the giraffe also has long eyes. These come in handy for vision as the giraffe can spot predators a long way off.

These animals are found in Sub-Saharan Africa and to the south as well. Although each of the animals is spotted, the spotting is unique.

To tell the difference between male and female giraffes, you can look at the ossicones which are the knobs on the giraffes’ heads.

The females have smaller knobs covered in some fur while the male ones have bald knobs. In addition to this, the males are much heavier and taller than their female counterparts.


2. Gazelle

Gazelles are relatively small mammals that are found in grasslands. They feed in these areas and are therefore prone to attack from predators.

There are two main types of gazelles. They are the Thompson gazelle and Grant’s gazelle. Both have a tawny color with white and brown markings on their bodies.

The only major difference is usually in their size as the Thompson gazelle is smaller. These animals have a stotting movement as part of their defense mechanism.

This type of movement can be referred to as bouncing around. It is supposed to chow predators that they are fit an agile and so pursuing them will resort to nothing since they cannot catch up.

They eat fruits, berries, shoots, fish and deer to name but a few things. Additionally, the females rear their cubs for two or three years before they let them go off on their own.

Towards the end of summer, the grizzly bears enter hyperphagia. During this time, they increase their calorie intake drastically and can gain up to three pounds a day.

This is necessary as it prepares the bears for winter during which they will not have access to a lot of food.

The insects are herbivores so they feed on greenery and plants. Some of these insects actually have an ecological role to play in crop rearing.

However, most of them have destructive behavior and should thus be dealt with if you are trying to grow your plants to maturity without damage.

Another interesting fact about these grasshoppers is that they perceive smell through their antennae. They also perceive touch through different parts of the body.

One of the eight wonders of the world is actually the migration of the land mammals after the rainy season. The stamping of their hooves actually stimulates grass growth as opposed to destroying it.

Gnus sleep on the ground in multiple rows. This provides them with enough space in case they need to run as well as the numbers required for protection in case there is a predator.

Another interesting fact about these mammals is that their young ones are born at the beginning of the rainy season and they can stand and run within three to seven minutes after they are born.

This is why you will likely come across a gecko in the wee hours of the night. Geckos do not have eyelids so that they cannot blink.

Instead, they have a colorless membrane which protects their eyes. From time to time, you can see a gecko licking their eyes.

This is necessary to clean them and is probably not painful. The fact that they lick their eyes supports this, otherwise, they would not.

These lizards have an interest defense mechanism which involves losing their tail. For most species, you have to touch the tail for it to come off.

However, there are species which can dispose of the tail at will. After a while, the geckos come to check whether the tail is still there. If it is, they eat it.
