The size of a stone crab claw is considered to be the length of the propodus. The propodus is the larger, immovable part of the claw. Legal-sized (harvestable size) claws are 70 mm (2 3/4 inches) or greater in propodus length.
Blood is called a connective tissue because it carries with it many digestive substances, oxygen from lungs, foods from small intestines and provide it to other tissues and organs of the body.
Blood is considered a connective tissue for two basic reasons: (1) embryologically, it has the same origin (mesodermal) as do the other connective tissue types and (2) blood connects the body systems together bringing the needed oxygen, nutrients, hormones and other signaling molecules, and removing the wastes.lood is considered a connective tissue for two basic reasons: (1) embryologically, it has the same origin (mesodermal) as do the other connective tissue types and (2) blood connects the body systems together bringing the needed oxygen, nutrients, hormones and other signaling molecules, and removing the wastes.
