287 Diaz blueworm
P1: CR heatworm and blueworm both are Diaz blueworms
P2: heatworm’s cilia: help to expel food and easier to live in the tree bark. Cilia从由keratin组成的表皮中突出，同时又调节着keratin的繁殖. cilia的movements vary as external temp change so respond quickly to thermostatic system, adjust keratin so worm won’t overexposed or stifled（窒息，受压制的）
P3: 另一个有cilia的就是blueworm. Heatworm’s thermostatic system 和blueworm的一样。但是blueworm的keratin用来在严寒下保暖。Cilia sense high temp so keratin slow down
P4: genetic testing showed blueworm and heatworm were not merely structurally similar but actually they are identical. Although they are different in size which causes by keratin.
