The pink squat lobster's body might look like an octopus or spider but don't let this little guy fool you! It can grow up with colors varying from browns and reds all the way down to oranges and yellows depending on where they live. This means if you are looking at one of these lobsters chances are pretty good it may have a pretty color. These lobsters are found on rocky seabeds off southern New England and down to Florida as well as around Indonesia and California where they make their home under rocks or corals for protection from predators like crabs. This squat lobster species does not have claws and therefore remain at seafloor level where they feed by grabbing prey with their powerful pincers, though some are also known to scavenge among dead fish or crabs if need be.
