Gas Bubble Sizes for Selected Myctophids,

Abstract

The mesopelagic animals which are most often detected acoustically are those which contain gas bubbles within their bodies. In the waters off the Oregon coast, the most abundant animals which contain gas bubbles are myctophids. Both the size and the shape of the bubble are important to acoustic measurements. This report summarizes the available information on the acoustically important characteristics of the most abundant myctophids: Stenobrachius leucopsarus, Diaphis theta, Tarletonbeania crenularis, and Protomyctophum thompsoni and crockeri.
