Caprella acanthifera is a species of amphipod crustacean belonging to the family Caprellidae. These fascinating creatures are commonly known as “skeleton shrimp” due to their slender, elongated bodies that resemble a skeletal structure.
Description & Characteristics
Caprella acanthifera exhibits a characteristically elongated body, with a length reaching up to 20 millimeters. Their bodies are segmented, with a distinct head, thorax, and abdomen. The head bears a pair of prominent antennae, while the thorax displays several pairs of legs used for locomotion and feeding. The abdomen, while smaller than the thorax, is also segmented and terminates in a pair of uropods, which are small appendages that assist in swimming.
Habitat and Occurrence
Caprella acanthifera is a marine species that predominantly inhabits the intertidal zone and shallow subtidal regions. This species typically resides on macroalgae, particularly the brown alga Fucus, and seagrasses. This attachment to these substrate types makes it a prevalent presence in these aquatic ecosystems. The depth range for Caprella acanthifera varies depending on the location, but generally extends from the low intertidal zone down to depths of 15 meters.
Taxonomy
The species Caprella acanthifera belongs to the Class: Malacostraca, Order: Amphipoda, and Family: Caprellidae. The Caprellidae family is a diverse group of amphipods, commonly known as “skeleton shrimps,” characterized by their slender, elongated bodies and specialized adaptations for living among marine vegetation.
Feeding
Caprella acanthifera is a carnivorous feeder, primarily consuming small invertebrates and other organisms found on its preferred macroalgal and seagrass substrates. These organisms typically include microscopic algae, diatoms, and small crustaceans.
