The leatherjacket (Parika scaber) is a balistiform fish which swims using its dorsal and anal median fins. The muscles controlling these fins are well vascularised, with control of blood flow effected by arterioles. These arterioles are long with a single layer of smooth muscle surrounding the endothelium, although the amount of contractile material is sparse, probably a consequence of the low blood pressure. The endothelial cells contain microfilaments, probably contractile, running along the length of the arteriole. The function of this material is unknown.
裸盖鱼（Parika scaber）是一种鲀形目鱼类，它利用背鳍和臀鳍中部来游动。控制这些鱼鳍的肌肉血管分布丰富，血流量由小动脉控制。这些小动脉很长，内皮周围有单层平滑肌，尽管收缩物质的量很少，这可能是低血压的结果。内皮细胞含有微丝，可能具有收缩性，沿小动脉长度分布。这种物质的功能尚不清楚。
