Cartilage Cartilage is a flexible but strong supportive connective tissue. Unlike bone and all other connective tissue types, cartilage is avascular, lacking blood vessels. For this reason alone, cartilage does not possess the regenerative capacity of bone or the other connective tissue types. Remember, nutrient delivery is essential for tissue repair.
The flounder is a species of flatfish that is found in the coastal waters of the northern Atlantic and Pacific Oceans. Flounder are found hiding on the ocean floor at depths from shallow coral reefs to the deepest trench on Earth.
Most puffers are found in tropical and subtropical ocean waters, but some species live in brackish and even fresh water. Some species of pufferfish are considered vulnerable due to pollution, habitat loss, and overfishing, but most populations are considered stable.
