The beautiful sea stars (“starfish”), classified as echinoderms, are one of the most easily identifiable marine invertebrates, with their characteristic radiating arms and stony skin of calcium carbonate. The sea star’s water vascular system is one of the more amazing and complex arrangements in the animal world.

The element nitrogen is critical in the living world. It is a basic building block of structural and regulatory proteins, nucleic acids, and chlorophyll in plants. God created the nitrogen metabolic networks found in people and various living organisms.

Animals designed to fly are classified into four groups: the extinct flying reptiles (pterosaurs), insects, mammals (bats), and birds. According to the creation model, bats and birds were created on Day 5 as bats and birds.

The lepidosaurs are a large and diverse group of land vertebrates that include the snakes and lizards. There are almost 12,000 species of these animals. But evolutionists still do not know where they came from. Vertebrate paleontologist Michael Benton stated, “The early history of squamates [snakes, lizards] is patchy,” and the debate of snake origin “is far from resolved.”¹
