Expanding or contracting fishing lure

A contracting fishing lure, comprising:

• a continuous body portion, wherein the body portion comprises a first open end and an opposite second open end;
• a cup or bowl-shaped head portion, wherein the head portion is adjacent the first open end of the body portion;
• wherein an open end of the cup or bowl-shaped head portion is forward facing;
• a channel extending longitudinally through the body portion;
• a series of flexible ridges and valleys extending around the body portion;
• a tail portion adjacent the second open end of the body portion and opposite the head portion;
• a fishing hook;
• a fishing line, wherein the fishing line is drawn through an opening in the head portion, further drawn through the channel extending longitudinally through the body portion, continued through the tail portion, and attached to the fishing hook via a means of attachment;
• the means of attachment directly attaching the fishing hook to the fishing line;
• a non-contracted first position in a natural state, wherein the body portion is in the non-contracted first position in water when the fishing line is slack;
• a contracted second position in a compressed state, wherein the body portion is in the contracted second position under action of water resistance as the contracting fishing lure is drawn through the water;
• and
• a significant difference in overall length of the contracting fishing lure while the contracting fishing lure is in the water between the non-contracted first position when the fishing line is slack and the contracted second position under action of the water resistance as the contracting fishing lure is drawn through the water to attract the attention of fish;
• wherein the significant difference in overall length is magnified by an increased water resistance exerted by the cup or bowl-shaped head portion against the water as the contracting fishing lure is drawn through the water;
• wherein the means of attaching the fishing line to the fishing hook extends further into the body portion while in the contracted second position under action of the water resistance as the contracting fishing lure is drawn through the water;
• wherein the contracting fishing lure transitions from the non-contracted first position to the contracted second position and back to the non-contracted first position to mimic the appearance of live bait to attract fish;
• wherein the means of attachment comprises a knot, ring, link or clip.
