1. A fish attachment apparatus, comprising:
a first attachment structure;
a second attachment structure; and
an intermediate structure coupled to the first attachment structure and the second attachment structure,
wherein the intermediate structure includes a front end and a back end, and
wherein the first attachment structure is coupled to the front end of the intermediate structure,
wherein the second attachment structure is coupled to the back end of the intermediate structure,
wherein the first attachment structure is configured to secure a first portion of the fish attachment apparatus to a front portion of a fish, and
wherein the second attachment structure is configured to secure second portion of the fish attachment apparatus to a back portion of the fish,
wherein: the first attachment structure includes a first arm, a second arm, a first protrusion with a sharp end and a second protrusion with a sharp end;
the first protrusion extends from the first arm in a first direction towards the second protrusion;
the second protrusion extends from the second arm in a second direction towards the first protrusion; and
the first arm and the second arm are movably coupled to each other or to the intermediate structure so as to allow the first protrusion to move in the first direction towards the second protrusion when a first directional pressure is applied to the first arm and the second protrusion to move in the second direction towards the first protrusion when a second directional pressure is applied to the second arm,
wherein: the first protrusion includes a first locking feature extending from a first surface of the first protrusion;
the second protrusion includes a second locking feature-extending from a second surface of the second protrusion;
the first arm and the second arm are movably coupled to each other or to the intermediate structure so as to allow the first locking feature to (a) move with the first protrusion in the first direction towards the second locking feature of the second protrusion, (b) make contact with the second locking feature, and (c) pass by the second locking feature;
the first arm and the second arm are movably coupled to each other or to the intermediate structure so as to allow the second locking feature to (a) move with the second protrusion in the second direction towards the first locking feature of the first protrusion, (b) make contact with the first locking feature, and (c) pass by the first locking feature; the first locking feature is configured to prevent the first protrusion from moving in the second direction opposite the first direction after the first locking feature has passed by the second locking feature and is in contact with the second locking feature; and
the second locking feature is configured to prevent the second protrusion from moving in the first direction opposite the second direction after the second locking feature has passed by the first locking feature and is in contact with the first locking feature.
