c. Scent cells
d. Colored pigment cells
ANSWER: Colored pigment cells
- Most cephalopods possess chromatophores - colored pigment cells that expand and contract in accordance with their counterparts to produce color and pattern - which they can use in a startling array of fashions.
- Cephalopods can change their colors and patterns in milliseconds, whether for signalling (both within the species and for warning) or active camouflage, as their chromatophores are expanded or contracted.
- Coloration is typically stronger in near-shore species than those living in the open ocean.
- These creatures’ (cephalopods like Octopus, Squids and Cuttlefish) change colour in response to external factors such as the presence of a predator.
