Response of the Organism: Hyalella azteca

Chemosensory organs in many crustaceans including Hyalella azteca allow them to locate food and mates while entirely avoiding predators. When detecting environmental changes such as the change in chemicals such as salinity, many amphipods have tiny hair-like organs containing sensory cells called sensilla (Hallberg, 2011). These chemosensory olfactory receptors are virtually found on many parts… View Article
