三刺棘鱼的侧板是修改后的鳞片，出现为单一的，双边的行。在它们的北方泛北极范围的大部分地区，淡水刺鱼的侧板形态表型是三态的（完全的，部分的和低的形态）。在发育过程中，完整的形态经过类似于低形态的阶段，然后是部分形态，然后达到最终的完整形态条件。在未成熟的完全型和成熟的部分型中，腹龙骨板和尾龙骨板的数量之间的关系可能是相似的。完全变形对于部分变形和低级变形来说是原始的。在未成熟的完全型和成年的部分型中，腹部和尾部龙骨板的数量之间存在类似的相关性。这种相关性的相似性表明，部分形态代表了完整形态的个体发育阶段，并通过幼态进化。可能有地理差异之间的相关性腹和尾龙骨板数。幼态侧板的表型主要由幼态持续演化;先成作用可能不太重要。这种侧板三型性的幼态模型与侧板形态遗传学是一致的。
Lateral plates of three-spined sticklebacks are modified scales that occur as single, bilateral rows. Throughout much of their northern Holarctic range, freshwater sticklebacks are trimorphic (complete, partial and low morphs) for the lateral plate morph phenotype. During development, the complete morph passes through stages that resemble the low morph and then the partial morph, before attaining the definitive complete morph condition. The relationship between the number of abdominal and caudal keel plates probably is similar in immature complete morphs and mature partial morphs. The complete morph is primitive to the partial and low morphs. A similar correlation exists between the number of abdominal and caudal keel plates in immature complete and adult partial morphs. The similarity of this correlation indicates that the partial morph represents an ontogenetic stage of the complete morph and evolved by paedomorphosis. There probably is geographical variation in the correlation between abdominal and caudal keel plate number. Paedomorphic lateral plate phenotypes evolved primarily by neoteny; progenesis may play a less important role. This paedomorphic model of lateral plate trimorphism is consistent with lateral plate morph genetics.
