Hewan Vertebrata tingkat rendah yang ektoterm mempunyai profil hematologi yang berbeda dengan Vertebrata tinggi yang sebagian besar endoterm. Tujuan dari penelitian ini adalah untuk membandingkan profil hematologi antar hewan Vertebrata yang meliputi lima kelas hewan takson. Hewan sampel diambil secara acak dari populasi hewan yang mewakili lima kelas takson: Clarias batracus dari kelas Pisces, Rana sp. dari kelas Amfibi, Eutropis multifasciata dari kelas Reptil, Columba livia dari kelas Aves dan Mus musculus dari kelas Mammalia.
