The Difference between Flathead Lobster and Vannamei Shrimp

Flathead lobster and vannamei shrimp differ significantly, even though they are both classified as crustaceans. These two differ from one another in terms of their physical characteristics, habitat, and market prices.

Physical Characteristics

Flathead lobsters are bigger in size and flatter in shape than vannamei shrimp. Their carapace is commonly red, brown, or black, and it has a rough, hard texture. Meanwhile, vannamei shrimp are transparent gray and smaller in size with a softer carapace.


Flathead lobsters are often found in coastal waters, which explains that they live in seawater. Meanwhile, vannamei shrimp live in brackish water, a mixture of freshwater and seawater. Vannamei shrimp can also be cultivated in farms for approximately 120 days.


Both flathead lobster and vannamei shrimp have high economic value. However, flathead lobster prices per kilogram tend to be higher as in Indonesia it ranges between IDR 120,000 and IDR 180,000. On the other hand, vannamei shrimp is more affordable because the largest size on the market (size 20) ranges from IDR 85,000 to IDR 95,000 per kilogram.


With their distinctive flat bodies, flathead lobsters live in coastal waters. There are two varieties of this species, namely the horned flathead lobster and red flathead lobster.

Flathead lobster have high economic value, but are difficult to get and cannot be cultivated like vannamei shrimp. Therefore, people are more interested in running a vannamei shrimp farming business.
