School-level biology can become infinitely more fun if school work is complemented by a little outside knowledge of the interesting world that we live in. It makes a lot of school work more interesting, bearable, and also gives it better context.
Let’s learn about sharks
Sharks do not have a single bone in their bodies. Instead they have a skeleton made up of cartilage which is the same type of tough, flexible tissue that makes up human ears and noses. Sharks have outstanding hearing. They can hear a fish thrashing in the water from as far as 500 metres away. A pup (baby shark) is born ready to take care of itself. The mother shark leaves the pup to fend for itself and the pup usually makes a fast getaway before the mother tries to eat it!Know more about lions
Lions are the second largest big cat species in the world (behind tigers). Most lions found in the wild live in southern and eastern parts of Africa. Lions are very social compared to other cat species, often living in prides (a group of lions) that feature females, offspring and a few adult males. Lions in the wild live for around 12 years.What do giraffes have to say?
A male giraffe can weigh as much as a pickup truck! That is about 1,400 kilograms. Although a giraffe’s neck is 1.5 1.8 metres, it contains the same number of vertebrae as a human neck. A giraffe’s habitat is usually found in the African savannas, grasslands or open woodlands.
