Placode olfactoria (Placodoma olfactoria) is a species of crustacean in the family Placidae that is found in tropical and subtropical waters around the world. These are small animals that are oval in shape and covered with hard plates.
The olfactory placode has several distinctive features that help it survive in its environment. First, she has sensitive hairs on her head that allow her to smell. These hairs are arranged in a network and serve to detect food.
Secondly, the olfactory placode can change color depending on the environment. It can change its color from white to brown, which helps it camouflage itself from predators. In addition, the placode has spines on its body, which serve for protection from other animals.
Overall, the olfactory placode is an important element of the ecosystem, as it plays an important role in the nutrition of other animals and is a predator of small fish and shellfish. However, due to its small size and sensitivity to environmental changes, the placode can become prey to other predators such as fish and birds.
