Radiolaria - several round segments decreasing to a point at one end, spines emerging from the other. Diatoms - extended straight body with spines emerging radially. Copepods - thin segmented bodies with 2 stalks at one end, emerging perpendicular to the body. Other phytoplankton - extended or compact bodies with green spots. Euphauslids - shrimp-like with segmented bodies and several pairs of legs. Foraminifera - made from several spherical sections. Salps - barrel shaped, extended bodies.
