Physical Appearance Gray whales are relatively large, twice the length of a killer whale, and half the length of a blue whale. Females whales are usually larger than male whales.
Gray whales have a long and narrow shape and are a medium gray colour marbled with lighter patches.
At the water surface they appear to be a whitsh-blue colour. Each whale has its own unique skin pattern which allows for identification. Their skin is smooth, and feels like a hard-boiled egg without the shell. The eyes of gray whales are brown and about the size of on orange. They steer themselves with their pectoral fins and power themselves with their tail.
