Crangon septemspinosa
Malacostraca (Subphylum – Crustaceans)
Range
Shrimp are found in all the world’s oceans, as well as in freshwater lakes and streams.Habitat
They live on the seabeds, often in shallow tidal pools.Body Traits
Shrimp are in a group of animals called “crustaceans.” This means instead of a backbone, they have a hard outside shell (exoskeleton). They are like crabs and lobsters, but their bodies are flattened from side to side and they have a hook shape. They have two pairs of antennae that can sense both taste and touch. They have 13 pairs of legs. The front 3 pairs are used for feeding (called maxillipeds), the next 5 are for walking (called pereiopods), and the last 5 that are on the abdomen are swimmerets (or pleopods). They can grow to be almost 3 inches long (7cm).Habits
They are active at night (nocturnal) feeding. During the day, they burrow into the sand.Diet
They eat small ocean animals (invertebrates) and plants.Reproduction
Females lay up to 15,000 eggs in a bunch under her tail. The eggs hatch and the larvae drift away. They grow and shed their hard outer skin (molt) over time. As they grow, they change into their adult form (metamorphosis).
