粗短鱿鱼是头足类动物，属于乌贼科，罗西那亚科和罗西亚属。 太平洋蔷薇分为两个亚种：太平洋蔷薇和太平洋蔷薇。 Diegensis仅在圣卡塔利娜岛附近的东太平洋海岸被发现。 它比其他R. pacifica物种更小，更细腻，鳍片更大，并且生活在更大的深度（近4,000英尺）内。 粗壮的鱿鱼看起来像章鱼和鱿鱼的混合物，但实际上两者都不是，与乌贼的关系更为密切。 粗短鱿鱼的身体光滑而柔软，短而圆，头上有两只大而复杂的眼睛。 从体内散发出来的是八个抽气的手臂和两个长的触手，它们会根据需要缩回和伸展以握住晚餐或彼此。 触角以也有吸盘的球杆结束。
The squid is a cephalopod, belonging to the genus Sepia, Rosinaki and Rosia. Pacific Rose is divided into two subspecies: Pacific Rose and Pacific Rose. Diegensis is only found on the eastern Pacific coast near Santa Catalina Island. It is smaller, more delicate, has larger fins, and lives at greater depths (nearly 4,000 feet) than other R. pacifica species. Stout squid looks like a mixture of octopus and squid, but in fact neither of them is more closely related to squid. The squid’s body is smooth and soft, short and round, with two large, complex eyes on the head. Effering from the body are eight pumping arms and two long tentacles that retract and stretch as needed to hold dinner or each other. The antennae end with a club that also has a suction cup.
