Leucophores

Definition

Leucophores are specialized cells in certain invertebrates that reflect ambient light, giving the appearance of white or silver coloration. They play a crucial role in camouflage and communication.

5 Must Know Facts For Your Next Test

1. Leucophores contain colorless, reflective platelets made of purines like guanine.
2. These cells are found in various molluscs, such as cuttlefish and octopuses, enhancing their ability to blend into their surroundings.
3. Leucophores work in conjunction with other chromatophore types to produce complex color patterns.
4. They can reflect a wide range of wavelengths due to the structure of their platelets, contributing to iridescence.
5. The function of leucophores is passive; they do not change color but rather reflect available light.
