The first larval stage (instar 1, 400 to 500 µm in length) has a brownish-orange colour, a red nauplius eye in the head region and three pairs of appendages, i.e. the first antennae (sensorial function), the second antennae (locomotory and filter-feeding function) and the mandibles (food uptake function).

PY - 1966. Y1 - 1966 The nauplius eye of the cyclopoid copepod Macrocyclops albidus has been studied by means of the electron microscope. It is composed of 1 ventral and 2 dorsal ocelli. Each dorsal ocellus consists of a large, pigmented cell, 2 tapetal cells which form a hemispherical cup and are tightly packed with crystals, 9 retinula cells and 5 conjunctival cells.

Nauplius eye

The second antennae and mandibles bear swimming setae. Additional trunk segments and appendages appear with successive moults, the increments proceeding from anterior to posterior. The investigated nauplius eye is the only one known with both a mirror and a highly refractive lens in the dioptric apparatus.

Larvae also develop a pair of compound eyes that appear only in the late nauplius … 2020-01-01 This eye, located atop the head, may have a lens and sense the direction of light but does not see images. In later stages, two more capable compound eyes develop on the sides but the initial eye may also stay, becoming the "third eye" of the creature. Nauplii may prefer to swim towards the light."
