| General Biology Additional Information | Pisidia longicornis is the most numerically abundant decapod crustacean in sublittoral areas. It occurs in densities of up to 640 /m² (Robinson & Tully, 2000a). Smaldon (1972) suggests that it "may survive to breed for a second or third season" suggesting a life span of up to three years. | ||||||||||||||
