This week's dissection had crayfish and worm. Much to my surprise, a worm has many aspects relating to humans. Their organs seem awfully similar to us, but of course, lack in size. The amount of organs were not alot. Their smell were from urine coming out of their skin. Crayfish ,on the other hand, is also very similar to the worm. They both have to rely on sense of touch since their visions are not very well, but what they lack in vision, means enhanced senses.
