Decapod crustaceans are probably the most important of all the invertebrates in the sea, as far as man is immediately concerned, because they are the most highly prized as food. Predatory fish also love decapod crustaceans. If you examine their stomach contents chances are there will be shrimp and small crabs. Here are a few of the many shrimp from the Gulf of Mexico.
Ar-1310 PINK SHRIMP, Penaeus duorarum/ Farfantepenaeus duorarium
They are not only delicious, but magnificent aquarium creatures with their large bodies, and round eyes on raised stalks. Pink shrimp burrow in the sand completely by day and dance in the water column by night, scavaging actively on whatever you throw in the tank. The diurnal white shrimp, Penaeus setiferus (or Litopenaeus setiferus if you must!) may be supplied when pinks are not available.

Ar-1340 PISTOL SHRIMP, Alpheus heterochaelis
A greenish blue shrimp that lives in burrows under oyster clusters, periodically emitting a loud, resounding “pop” that can be heard some distance away. The noise comes from the snapping of the one oversized, highly modified pincer of the first of two pairs of pincers and is used to attack prey. Pistol shrimp are usually found in mated pairs. Size: 3-5 cm.
Ar-1360 GRASS SHRIMP, Palaemonetes pugio
They are a small shrimp so transparent they hardly cast a shadow. In the winter the tidal creeks seethe with them, providing food for a tremendous number of estuarine fishes, wading birds, alligators, etc. They also provide research opportunities for scientists working with the hormonal control of chromatophores in endocrinology, and are classical subjects in water quality/pollution work. In summer their numbers are greatly diminished by predators, but their rapid reproduction quickly builds their numbers back in the fall. They have a life cycle of one year and can reach maturity in 2 to 3 months. Ovigerous females available from March to October.

Ar-1370 ZEBRA GRASS SHRIMP, Palaemon floridanus
A clear caridean shrimp with large red chromatophores and black stripes. Moving delicately around the aquarium, they sometimes exhibit cleaning behavior. Normally found in association with hydroids and fouling organisms, they are often encountered in sea grass beds. Gravid females are available December through April. Size: 2-4 cm.
Ar-1380 RED CLEANING SHRIMP, Lysmata wurdmanni
They provide a rare combination of exotic beauty and a unique display of cleaning symbiosis at its most primitive stage. The body is longitudinally striped with ruby red, and the ventral thorax bears striking “Y” shaped markings. When a spiny boxfish or filefish approaches, the shrimp begins rhythmically rocking to and fro. Ascending the vertical column of water in a peculiar walking motion, it mounts its “host” and begins picking off parasites. Red Cleaners will swarm over your fingers picking at dead skin or cuts, providing a classroom experience never to be forgotten. Size: 1.5-2.5 cm.
