Mammal Study (2019)
Studies on odontocetes (e.g., porpoises) have revealed that these animals may adaptively use vision. The present study examined the contributions of vision to the approaching behavior of the harbor porpoise…

(...) In this chapter, we discuss marine mammal audition, vision, chemoreception, tactile sensation, and magnetic detection. We begin with an overview of the basic aspects of sensory receptor systems, and…
(...) Organization of the visual system in Cetacea still remains unclear in many respects. Of special interest are data on ganglion cell distribution in the retina. It is related closely…
Several anatomical characteristics of the cornea, lens, iris and retina of the eyes of a month-old and an adult harbor porpoise (Phocoena phocoena) were investigated by scanning, transmission and light…

Dall's porpoises, Phocoenoides dalli, were often incidentally caught in the Japanese salmon gillnet fishery in the North Pacific. In order to investigate the reasons for entanglement, their auditory characteristics and…
The refractive index of the cornea of a harbor porpoise eye was measured by two-wavelengths laser-interferometry. In the thickest part of the cornea a refractive index of about 1.53 was…
