Pronunciation: [dˈɛntɪkə͡l] (IPA) 
The word "denticle" is spelled d-e-n-t-i-c-l-e. Its IPA phonetic transcription is /ˈdɛntɪk(ə)l/. The first syllable is pronounced with the short "e" sound, followed by the "n" sound, and then ends with the "t" sound. The second syllable starts with the "ih" as in "sit" sound and then has the "k" and "l" sounds. "Denticle" is a noun that refers to a small tooth-like projection or structure, particularly found in sharks and rays.
A denticle refers to a small, tooth-like projection or structure found on the surface of an organism, particularly in the animal kingdom. These tiny, often pointed structures are commonly seen on the bodies of certain creatures, such as arthropods or sharks. Denticles usually arise from the skin or exoskeleton and can serve various functions depending on the organism in question.
In arthropods, denticles can be found on the wings, legs, or other body parts, functioning as defensive structures. They act as protective armor, making it harder for predators to injure or capture the organism. Additionally, denticles may assist in enhancing the animal's mobility by increasing surface area and enabling better traction.
In the case of sharks, their skin is covered in numerous tiny denticle structures called placoid scales. These unique structures reduce turbulence in the water, enabling sharks to swim more efficiently. Furthermore, the rough texture of the denticles contributes to a shark's ability to swim silently, making them formidable hunters in their aquatic environment.
Overall, denticles are small, often tooth-shaped structures that serve various purposes across the animal kingdom. Whether providing defense, improved mobility, or hydrodynamics, these microscopic projections play a crucial role in the survival and adaptation of diverse organisms.
The word "denticle" has its roots in Latin and Greek. The Latin word "dēns" means "tooth", while the Greek word "díktos" means "tooth-like" or "pointed". The combination of these two roots gives rise to the word "denticle", which refers to a small tooth-like structure or a small pointed object resembling a tooth.
