In elasmobranch (Scyllium canicula, Galleus canis) and teleost (Migull capitocum) fishes it is possible to form motor food-searching conditioned reflexes to discrimination of light and darkness. Some differences were revealed in ecological and conditioned motor behavioural activities in higher and lower sharks. Elasmobranch and teleost fishes exhibit significant differences in ecological, feeding and conditioned reflex behaviour. Nervous activity in elasmobranchs is characterized by lower and primitive organization as compared to that in teleosts.
在软骨鱼（斑纹鲨、犬鲨）和硬骨鱼（黑背鼻鱼）中，可以形成对明暗辨别进行食物搜索的运动性条件反射。在高等和低等鲨鱼的生态和条件性运动行为活动中发现了一些差异。软骨鱼和硬骨鱼在生态、摄食和条件反射行为方面表现出显著差异。与硬骨鱼相比，软骨鱼的神经活动具有较低和原始的组织特征。
