WALT: writing essays      crocodiles          by: Nicholas Bruni



Looming like a ghost through the murky waters of the Nile river, inching ever so closer to an unexpecting gazelle drinking at the edge of the river. Vanishing in a ripple of muddy water. The crocodile has evolved extremely deadly adaptations to kill its pray, and survive.

In order for crocodiles to kill their prey, crocodiles have to be fast and agile in the water. The crocodile’s tail muscle is extremely powerful. The tail moves in an S-shaped pattern to propel the reptile through the water.  When crocodiles are not moving forward they use their feet to paddle. Crocodile’s bodies are streamlined to make it easier to cut through the water, like a torpedo.

Crocodiles have to have a very strong defense and attack system in order to stay alive. A crocodile’s scales are made from keratin that almost coats the croc in armor. For greater defense  crocodiles can make their eyes go deeper into their sockets. The crocodile’s teeth are serrated and curve backwards. Crocodiles’ teeth are curved like this to make things easy to slide past but challenging to get out. On land the crocodile uses its thick tail to club other predators.

As the crocodile reaches the gazelle, with a flick of its thick tail it lunges forward. The crocodile’s serrated teeth dig deep into the neck of the gazelle. The gazelle desperately tries to get away by thrashing its head back and forth, but it is only making the teeth tear apart more flesh. The gazelle gives up from exhaustion and is dragged into the murky depths, drowning.
