The Red Reef Hermit Crab (Dardanus arrosor) is a decapod crustacean in the Diogenidae family of crabs. It is also known as the Mediterranean Hermit Crab.
The Red Reef Hermit Crab has a beige-coloured shell, called a carapace. The body of the Hermit Crab is hidden in the shell. The colour of its body varies from bright red to bright orange. Its eyes are at the tips of two eyestalks. The eyestalks are streaked red and white, and the eyes are bluish. It is a decapod, which means that it has ten appendages (two claws and eight legs). Its two red claws have a black or yellow tip. The claws have hair-like spines and warty tubercules. The left claw is larger than the right claw.

The Common Prawn (Palaemon serratus) is a marine (saltwater) crustacean in the Palaemonidae family of invertebrate ten-footed shrimp (decapod). It is related to the crab and the lobster.
The Common Prawn is transparent (see-through) to pinkish-brown with reddish striped-liked markings and patterns. It has an exo-skeleton (outside skeleton) called a carapace or shell. Its forward extension of the carapace in front of its eyes, called the rostrum, curves upwards. The rostrum is also bifurcated at the tip, which means that it is split into two parts. It has long, white antennae. It has bulging eyes. It has ten legs.

The Golden King Crab (Lithodes longispina) is a marine (saltwater) crustacean in the Lithodoidea family of crabs. However, many scientists think it should be classified in the Paguroidea superfamily of hermit crabs. It is a decapod because it has 10 limbs.
The Golden King Crab has five pairs of spiny limbs – 10 limbs. The front pair of legs has claws, or nippers. Its rounded-triangular exoskeleton shell (carapace) is pale orange with spines.

The Small European Locust Lobster is a decapod with ten legs, including a pair of claws. It has a reddish-brown exo-skeleton. Its abdomen has six segments, ending with a flattened, fan-shaped tail called a telson. It has a dark-brown spot in the centre of each abdominal segment. It also has dark-blue rings around each segment. It has eye-stalks. It has gills to enable it to breathe oxygen from the sea water.

The European Lobster (Homarus gammarus) is a marine (saltwater) clawed crustacean. It is also known as the Common Lobster. It is related to the American Lobster (Homarus americanus). Crustaceans include crabs, crayfish, and shrimps.
The European Lobster is a decapod with ten legs, including a large pair of claws or nippers. It has a hard, blue shell called an exo-skeleton. It has eye-stalks. The shell is covered with pointed tubercles (like mini-teeth). It has gills to breathe oxygen from the sea water. Its abdomen has six segments, ending with a fan-shaped tail called a telson.

The Deep-Sea Decapod Crustacean (Polycheles enthrix) is a blind, ten-limbed lobster-like crustacean. Polycheles means ‘many-clawed.’ It is often known as a ‘living fossil.’
The Deep-Sea Decapod Crustacean looks like a lobster or a shrimp, with a reddish-orange exo-skeleton. It has ten elongated chelate (clawed) limbs and a segmented tail. Because it lives in very deep oceans, where there is little or no light, its eyes are not functional, and therefore it is blind.

The Glypheoid Lobster (Neoglyphea inopinata) is a decapod (ten-legged) marine crustacean. Crustaceans include crabs and shrimp. The Glypheoid Lobster is related to the Spiny Lobster.
The Glypheoid Lobster has a hard exoskeleton (outer shell) with eye stalks. The shell is covered with pointed tubercles (like mini-teeth). It has gills to breathe oxygen from the sea water. Its abdomen has six segments, ending with a fan-shaped tail called a telson. It has 10 limbs.
