How many cone cells does a lobster eye have?

Lobsters have a unique visual system that includes compound eyes, which are made up of numerous ommatidia. Each ommatidium contains photoreceptor cells, but lobsters do not have cone cells like those found in vertebrates. Instead, they possess different types of photoreceptors that are sensitive to various wavelengths of light, allowing them to perceive their environment effectively. The exact number of these photoreceptors can vary, but they are adapted for underwater vision rather than the cone-based vision seen in many terrestrial animals.
