It is another exciting day in Perth again! When the bus off to Perth Hills, everyone was discussing about what we were going to do today. Our friendly guide, Mr C, took us into the deep forest to look for many types of invertebrates. Invertebrates are organisms that do not have backbone. Spiders, cockroaches, millipedes, centipedes, earthworms, ants, crickets and termites are example of invertebrates. Mr C told us to go into the forest where humans planted the long and tall tree in there in many rows. We threw a yellow round hoop on an area of soil and used a shovel to remove the twigs to search for invertebrates. I found out that the most common type of invertebrates are spiders, ants and millipedes. Spiders have eight legs, ants have six legs and millipedes have many legs.
I managed to catch six centipedes. Some were long and some were short. Next, we set off to the natural forest where the trees are naturally grown. There were more crickets there as compared to the first forest we visited. Crickets can hop from one place to another place to another at a very fast speed. I had much difficulty catching a cricket. But at last, we did not just capture the invertebrates to keep them, we released them back in the bushes again as there were very important to the environment. They help in the seed dispersal, pollination and many other important matters. I learnt a valuable and unforgettable experience during this programme.
