Alpheus heterochaelis, commonly known as the Alpheus Heterochaelis, is a fascinating species of snapping shrimp found in various marine environments. These crustaceans are characterized by their striking asymmetry, with one large, dominant claw that is used for a powerful snapping action. The sound produced by this snap is incredibly loud, sometimes reaching levels comparable to a gunshot, and is used for a variety of purposes, including communication and hunting.
Description & Characteristics
Alpheus heterochaelis is a relatively small shrimp species, with adults typically reaching a maximum size of around 3.5 centimeters in length. They exhibit the characteristic features of their family, the Alpheidae, with a robust body and a pair of asymmetrical claws. The most notable feature is the large, dominant claw, often referred to as the “snapping claw,” which is significantly larger than the other claw and is used for producing the signature snapping sound. The carapace, or the hard outer shell covering the head and thorax, is typically brown to olive green in color, while the abdomen may exhibit a lighter coloration.
Habitat and Occurrence
Alpheus heterochaelis is found in a variety of marine habitats, primarily in shallow, coastal waters. They are commonly found in association with coral reefs, seagrass beds, and rocky shores, often residing in crevices and burrows. These shrimps are well-adapted to life in these environments and play a significant role in the overall health of these ecosystems.
Taxonomy
Alpheus heterochaelis belongs to the Class: Malacostraca, Order: Decapoda, and Family: Alpheidae. The Malacostraca class includes a diverse range of crustaceans, including crabs, lobsters, and shrimp. Within this class, the Decapoda order encompasses species that possess ten legs, which are often modified for various functions like walking, feeding, and defense. The Alpheidae family, to which Alpheus heterochaelis belongs, is specifically characterized by the presence of the aforementioned asymmetrical claws.
Feeding
Alpheus heterochaelis is a carnivorous species, feeding primarily on a variety of small invertebrates, including brine shrimps, flakes, frozen food (large sort), mysis, schrimps, shrimps, and zooplankton. These shrimps use their powerful snapping claws to stun or kill their prey before consuming them.
