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.
Bones and blood are both considered to be connective tissues. Muscle tissue is significant because of its ability to contract and relax in order to exert force on the outside world. There are several different types of tissue that fall into the category of muscle tissue. Smooth muscle tissue, for example, lines the insides of some organs and skeletal muscular tissue is used for movement and for purposeful force. The heart is composed of a specific kind of muscle tissue known as cardiac muscle.
