What similes are used in The Interesting Narrative and Other Writings by Olaudah Equiano?

From the text:

We have many musical instruments, particularly drums of different kinds, a piece of music which resembles a guitar, and another much like a stickado.

They are made something like an anchor; but I do not remember either their value or denomination.

I remember two of those ominous snakes, each of which was as thick as the calf of a man's leg, and in colour resembling a dolphin in the water, crept at different times into my mother's night-house, where I always lay with her, and coiled themselves into folds, and each time they crowed like a cock.
