Creation Day 5 G od creates animal life in Earth's waters and skies Genesis 1:20-21
Meet three advanced Cambrian Echinoderms that also defy Evolution!
Beautiful starfish are one of the most easily identifiable marine echinoderms, with their five radiating arms and spiny hard skin (exoskeleton) made up of calcium carbonate.
God created the echinoderm's vascular system as one of the more amazing arrangements in the animal world. Each of the five arms has a special radial canal running down its length.
Carefully study the diagrams above showing the internal organs found inside a sea urchin and a starfish. Water circulates through these structures allowing for gases, nutrients, and waste to pass in and out of an echinoderm's body. A structure on top of the body, called the madreporite, regulates the amount of water that enters a echinoderm's vascular system. God designed echinoderms with special tube feet which
protrude through openings along the sides and bottoms of their exoskeleton. Tube feet provide movement by expanding and contracting using water being circulated throughout the echinoderm's internal vascular system.
