More About Lobsters ...

Clawed lobsters comprise a family (Nephropidae) of large marine crustaceans. Smaller varieties are sometimes called "lobsterettes". Lobsters are invertebrates, and have a tough exoskeleton, which protects them. Like all arthropods, lobsters must molt in order to grow, leaving them vulnerable during this time. Lobsters are considered a food delicacy around the world.
Lobsters live on rocky, sandy, or muddy bottoms from the shoreline to beyond the edge of the continental shelf. They generally live singly in crevices or in burrows under rocks. Lobsters are basic scavengers, feeding on mollusks and decaying animal matter. Lobsters are not entirely scavengers, they also eat live fish, dig for clams, and feed on algae and eel grass. An average adult lobster is about nine inches (230 mm) long and weighs 1.5 to 2 pounds (700 to 900 g), although lobsters grow throughout their lives and are long-lived, and can thus reach impressive sizes. According to the Guinness World records, the largest lobster was caught in Nova Scotia, Canada and weighed 20.14 kg (44.4 lb).
The environmental conditions of the lobsters can vary from ocean to ocean, but the lobster’s temperature environment does not fluctuate much since their home is large mass of water, the ocean.
Like all arthropods, lobsters are bilaterally symmetrical. The anatomy of the lobster includes the cephalothorax which is the head fused with the thorax, and the abdomen both of which are covered by the carapace. The lobster’s head consists of antennae, antennules, mandibles, the first and second maxillae, and the first, second, and third maxillipeds. Because a lobster lives at the bottom of the ocean, vision is poor so the lobster uses its antennae as sensors. The abdomen of the lobster includes swimmerets and its tail which is composed of uropods and the telson
