    They aerate soil when they move, as they consume and excrete soil in front of them to create pathways of movement

    During rain, some worms venture out from the soil to find mates, though they risk the danger of drying up when the rain abates]]>     2022-04-25 17:51:49 UTC https://padlet.com/hmathew6/cnw7cwqa0qc5hd6u/wish/2157063841     Annelids nishantperla25_2 https://padlet.com/hmathew6/cnw7cwqa0qc5hd6u/wish/2157068336 Annelids have a powerful, segmented body that can be used for burrowing.
    There are also over 15,000 species all over the world.
    They don’t have a skeleton; instead, they have a nervous system and a gut that runs from head to tail.

    - They have adapted to almost all of the different environments on Earth including the deep sea.
    - They have a segmented body with strong muscles and an advanced nervous system.
    - One example is the sabellid which has a head that looks similarly to a flower and it collects food and nutrients from the water around it.]]>     2022-04-26 15:14:23 UTC https://padlet.com/hmathew6/cnw7cwqa0qc5hd6u/wish/2158721336     Echinoderms rachelmantyla25_1 https://padlet.com/hmathew6/cnw7cwqa0qc5hd6u/wish/2158742093 - They are based on a 5 body part plan. 
    - They have a nerve ring instead of a brain.
    - They have no head, face or eyes most of the times and instead use nerves on the end of feet and tubes to tell their surroundings. 
    - One example is the sea urchin which has a mouth hidden behind a bunch of feet that sense and bring food to it.]]>     2022-04-26 15:24:37 UTC https://padlet.com/hmathew6/cnw7cwqa0qc5hd6u/wish/2158742093     sienaduke25_2 https://padlet.com/hmathew6/cnw7cwqa0qc5hd6u/wish/2160743821 1. They were the first creatures to venture to land. 

    2. They eventually evolved to be able to fly. An adaption that now is present in over 3/4 of the insect population. 

    3. Predators, like the spider, adapted to be able to catch flying creatures with weapons like webs. ]]>     2022-04-27 16:48:19 UTC https://padlet.com/hmathew6/cnw7cwqa0qc5hd6u/wish/2160743821     sienaduke25_2 https://padlet.com/hmathew6/cnw7cwqa0qc5hd6u/wish/2160758461 1. They are based off a five part symmetry. 

    2. Their censor receptors pick up light and darkness but cannot create images.

    3. They mostly prey on easy victims like mussels that cannot run away or fight back. ]]>     2022-04-27 16:57:19 UTC https://padlet.com/hmathew6/cnw7cwqa0qc5hd6u/wish/2160758461
