crustacean are various predominantly aquatic arthropods of the class Crustacea, including lobsters, crabs, shrimps, and barnacles, characteristically having a segmented body, a chitinous exoskeleton, and paired, jointed limbs
Amollusks is a numerous chiefly kinds of marine invertebrates of the phylum Mollusca, typically having a soft unsegmented body, a mantle, and a protective calcareous shell and including the edible shellfish and the snails.

Which animals has bule blood?

Do pearls come from arthropods?

Does Arthropods have a rigid outer covering called mantle?
No, the rigid outer covering of arthropods is usually called the exoskeleton. In biology the mantle is a major anatomical component of a different phylum - molluscs, the tissue which contains the internal organs and in many molluscs responsible for secreting the mineralized outer shell.
What is an extinct group of marine arthropods?
Trilobites, and eurypterids (giant marine scorpions). Ammonites are not arthropods but molluscs.
What are the group of invertebrates?
In total there are 8 groups of invertebrates:-Insects-Arachnids-Crustaceans-Millipedes-Worms-Molluscs with shells-Molluscs without shellsThe groups of Invertibrates are Coelenterates, Echinoderms, Mollusks, Arthropods, Annelids, Plathelminths, Poriferas and Nematodes.
Do arthropods and mollusks have lungs?
No for arthropods; yes for some molluscs. The larger aquatic arthropods like lobsters and crabs accomplish gas exchange using gills. Smaller ones like the land-based insects have holes (spiracles) in the exoskeleton and a tube system to facilitate gas exchange necessary for respiration. In this case, unlike mammals which use lungs to oxgenate blood which is pumped to the tissues, the tracheal tubes from the spiracles deliver oxygen directly to the tissues. Aquatic molluscs have gills for gas exchange whereas molluscs adapted to live on land like snails do have a lung.
What is the difference between octopus and shark?
Octopi are cephalopod molluscs, have 8 legs and are often depicted squirting ink when they get cranky. Sharks are fish.
What are the phyla's?
In no particular order: Chordates Echinodermata Platyhelminthes (Flatworms) Nematodes (Roundworms) Annelids (Segmented Worms) Arthropods Porifera (Sponges) Molluscs (Shells)
