That creates problems with shrimp-like species that are not small. Prepping from sea to table is more of a challenge because the shrimp must be frozen immediately after the catch, whereas crabs and lobsters must remain alive until cooked. Various species have occupied almost every conceivable niche within the aquatic environment. [4] New Zealand broadly follows British usage.
