Macrodactyla
Macrodactyla is a genus of deep-sea lobsters, with a single known species, Macrodactyla bathypelagica. It is a unique and remarkable species, known for its unusually long and slender claws, which distinguish it from all other lobsters.
Common Names
Macrodactyla bathypelagica is commonly known as the "long-clawed lobster" or "giant spiny lobster". While the latter name may be confusing as it is also used for other lobster species, it emphasizes the distinctive long spines found on its body.
Characteristics
Macrodactyla bathypelagica is characterized by its impressive size and unique morphology. Adults can reach lengths of over 40 cm (16 inches), with their most striking feature being their exceptionally long and slender claws. These claws are significantly longer than the lobster's body and are covered in sharp spines. They are thought to be used for defense and predation.
Other notable characteristics include:
- A robust, cylindrical body with a hard, calcified exoskeleton.
- A large, prominent rostrum (a beak-like projection on the head) that extends forward.
- Two pairs of antennae, with the first pair being much longer than the second.
- Ten walking legs, with the first pair modified into the large, clawed appendages.
- A pair of swimmerets, used for swimming and reproduction.
Environments
Macrodactyla bathypelagica is a deep-sea species, typically inhabiting depths of 300 to 1,000 meters (980 to 3,280 feet). It prefers environments with soft, muddy bottoms and is often found near hydrothermal vents or cold seeps, where it feeds on invertebrates and small fish.
