The tentacles of a squid are appendages that have been modified from <u>foot.</u>
Further Explanation:
Molluscs are invertebrates and they are the second-largest phylum, the largest phylum is arthropods. Molluscans have around 84,000 species. There are many species which live in freshwater and terrestrial habitats.
Molluscs have many different classes such as,
• Gastropods
• Cephalopods
• Bivalvia
• Aplacophora
• Scaphopoda
• Polyplacophora
• Monoplacophora
Squid are a type of Cephalopods; they have two tentacles, 8 arms, large eyes, and elongated body
The symmetry of squid’s body is bilateral. They are externally soft and internal skeleton is hard made up of chitin. Squid use bioluminescent activity to distract the predator. They use tentacles to grab food and arms are used to hold the food.
Some other examples of Cephalopods are <u>Octopus</u> and <u>Nautilus</u>.
The pair of tentacles is modified from primitive molluscan foot; they can reach to a length of 8 meters in 15 milliseconds. They are part of the locomotory system of squid.
