What is mimicry in arthropods?

Back

Mimicry is a survival strategy where a non-toxic species, like the viceroy butterfly, resembles a toxic species, such as the monarch butterfly, to avoid predation.

Front

What is the cephalothorax in crayfish?

Back

The cephalothorax is the combined head and thorax region of a crayfish, housing the stomach, gills, and reproductive organs, and is associated with the eyes, antennae, mouth, and walking legs.

Front

What role do enzymes play in arthropod molting?

Back

Enzymes are responsible for dissolving the inner layer of an arthropod's old exoskeleton during the molting process.

Front

What unique feature do mantis shrimp possess?

Back

Mantis shrimp have 16 different color receptor cells in their eyes, allowing them to see a broader spectrum of colors than most other animals.

Front

What are swimmerets in crustaceans?

Back

Swimmerets are small appendages found on the abdomen of crustaceans, involved in locomotion, reproduction, and respiration, and can help capture food particles.

Front

Define aposematic coloration.

Back

Aposematic coloration is a warning coloration used by toxic species to signal potential predators about their toxicity.

Front

What is the function of chelipeds in crustaceans?

Back

Chelipeds are the large pincers or claws of crustaceans, used for defense, capturing prey, and manipulating objects.

Front

Explain the term 'exoskeleton' in arthropods.

Back

An exoskeleton is a hard outer structure that provides support and protection to arthropods, made primarily of chitin.

Front

What is the significance of compound eyes in arthropods?

Back

Compound eyes allow arthropods to have a wide field of vision and detect motion effectively, enhancing their ability to evade predators.

Front

Describe the process of molting in arthropods.

Back

Molting is the process by which arthropods shed their old exoskeleton to grow, involving the secretion of enzymes to dissolve the old exoskeleton and the formation of a new one.
