Each rib extends along a longitudinal direction and has a first surface and a second surface opposite to the first surface in a transversal direction. The first surface has first protrusions and a first valley between every two adjacent ones of the first protrusions. The second surface has second protrusions and a second valley between every two adjacent ones of the second protrusions. The first protrusions of a respective rib can enter into the second valleys of an adjacent rib, and the second protrusions of the adjacent rib can enter into the first valleys of the respective rib. The respective rib allows the adjacent rib to rest thereon. Therefore, the bionic bait in the flow can swing like a live fish. ## Claims ### Claim 1 A bionic bait comprising: a bait body including an imitation trunk, the imitation trunk including a spine sheet and a plurality of ribs at each of two opposite lateral surfaces of the spine sheet, each of the plurality of ribs extending along a longitudinal direction and including, in a transverse direction, a first surface and a second surface opposite to the first surface, the first surface being provided with a plurality of first protrusions and a first valley between every two adjacent ones of the plurality of first protrusions, and the second surface being provided with a plurality of second protrusions and a second valley between every two adjacent ones of the plurality of second protrusions, wherein the first plurality of protrusions of each of the plurality of ribs are capable of entering into the second valleys of an adjacent one of the plurality of ribs, the first valleys of each of the plurality of ribs allow the plurality of second protrusions of an adjacent one of the plurality of ribs to enter thereinto, and each of the plurality of ribs allows an adjacent one of the plurality of ribs to rest thereon. ### Claim 2 (depends on 1) The bionic bait as claimed in claim 1, wherein each of the plurality of first protrusions includes a first upper support surface and a first lower support surface, an angle between the first upper support surface and the first lower support surface is greater than 0 degree and less than 180 degrees, each of the plurality of second protrusions includes a second upper support surface and a second lower support surface, and an angle between the second upper support surface and the second lower support surface is greater than 0 degree and less than 180 degrees; and two adjacent ones of the plurality of ribs are defined as a first rib and a second rib, and when the first rib and the second rib abut against each other, the first upper support surface of at least one of the plurality of first protrusions of the first rib abuts against the second lower support surface of at least one of the plurality of second protrusions of the second rib or the first lower support surface of at least one of the plurality of first protrusions of the first rib abuts against the second upper support surface of at least one of the plurality of second protrusions of the second rib. ### Claim 3 (depends on 1) The bionic bait as claimed in claim 1, wherein the bait body further includes an imitation head disposed at a front end of the imitation trunk. ### Claim 4 (depends on 3) The bionic bait as claimed in claim 3, wherein the bait body further includes a resistance member, which is disposed to the imitation head. ### Claim 5 (depends on 3) The bionic bait as claimed in claim 3, wherein the bait body further includes at least one selected from an imitation tail fin, an imitation dorsal fin, an imitation pelvic fin, an imitation anal fin and a pair of imitation pectoral fins, the imitation dorsal fin is disposed on a top of the imitation trunk, the imitation tail fin is disposed at a rear end of the imitation trunk, the imitation pelvic fin and the imitation anal fin are disposed at a bottom of the imitation trunk, and the pair of imitation pectoral fins is respectively disposed at two opposite sides of the imitation trunk. ### Claim 6 (depends on 1) The bionic bait as claimed in claim 1, wherein the bait body further includes at least one accommodation groove. ### Claim 7 (depends on 6) The bionic bait as claimed in claim 6, wherein the accommodation groove is located in the imitation trunk. ### Claim 8 (depends on 7) The bionic bait as claimed in claim 7, wherein the bait body further includes an imitation dorsal fin, the imitation dorsal fin is disposed on a top of the imitation trunk and includes two dorsal fin pieces, and the accommodation groove is disposed at the top of the trunk and at least partially located between the two dorsal fin pieces. ### Claim 9 (depends on 7) The bionic bait as claimed in claim 7, wherein the bait body further includes an imitation pelvic fin, the imitation pelvic fin is located at a bottom of the imitation trunk and includes two pelvic fin pieces, and the accommodation groove is located at the bottom of the imitation trunk and at least partially located between the two pelvic fin pieces. ### Claim 10 (depends on 1) The bionic bait as claimed in claim 1, wherein the bait body is made of elastic material.
