Lancelet fish (Branchiostoma) is sometimes called amphioxus, the type of the class Leptocardii, is a little creature, half and inch to four inches long. A lancelet may be regarded as a vertebrate reduced to its lowest terms. Instead of a jointed backbone, it has a cartilaginous notochord, running from the head to the tail. A nervous cord lies above it, enclosed in a membranous sheath. No skull is present and the nerve cord does not swell into a brain There are no eyes and no scles. The mouth is a vertical slit, without jaws. In this diagram we see the California lancelet twice the natural size, showing (g) gills, (l) liver, (m) mouth, (n) nerve cord, (nc) notochord.

Flounder have both eyes situated on one side of the head, they are not born this way. Their life involves metamorphosis. During metamorphosis, one eye migrates to the other side of the body so that both eyes are situated on the upward-facing side of its body. After metamorphosis, flounder lie on one side on the ocean floor; either the left or right side might face upward depending on the species. This is the different stages of the flounder. Note the eyes in the young flounder are arranged one on each side of the head.

Mackerel is a common name applied to a number of different species of fish, mostly, but not exclusively, from the family Scombridae. They occur in all tropical and temperate seas. Most live offshore in the oceanic environment but a few, like the Spanish mackerel (Scomberomorus maculatus), enter bays and can be caught near bridges and piers. Common features of mackerels are a slim, cylindrical shape (as opposed to the tunas which are deeper bodied) and numerous finlets on the dorsal and ventral sides behind the dorsal and anal fins.
