Blog 13 What was most interesting about this week's dissections?

crayfish.gifThis week's dissection about claw fish actually impress me a lot.Not only because l like eat this,but also l feel interesting about its complex internal system.lt has a brain same as human,but its heart is kind of big if you compare to its small body.lnstead of have a lung to do respiration.lt has a big gill.lts degestive system is from intestine to anus,lt is quite similar to human.lt uses its walking legs to crawl.lt may work effective because it has many of them.
