Squat Lobster
Squat lobsters are invertebrates with a hard protective exoskeleton. Like most arthropods, these lobsters must molt in order to grow, which leaves them vulnerable. During the moulting process, several species change color. Like most other arthropods, these lobsters are largely bilaterally symmetrical.
The squat lobster anatomy includes the cephalothorax which combines the head and the thorax. The lobster's head bears antennae, mandibles and the first, second, and third maxillipeds. Because lobsters live in a murky environment at the bottom of the ocean, they mostly use their antennae as sensors, which is why they are placed under so much protection. The lobster eye has a reflective structure above the convex retina.
