Transcript of The Characteristics Of Life For Brine Shrimp

The Characteristics Of Life For Brine Shrimp By: Curran Wood
Cellular Makeup

The Brine Shrimp is one of the few multicellular organisms that have flourished in the Great Salt Lake.
The female brine shrimp are able to fertilize their own eggs without the males help. This is called parthenogenesis. Later, males are required to produce over wintering cysts. The production of cysts provides sexual reproduction which means males need to contribute sperm to the egg.
Reproduction
The Brine shrimp gene spans a genomic region of 15 kilobases, the only gene of the engrailed present in the Brine shrimp genome, this is 349 amino acids long.
Genetic and DNA Makeup
1. Dormant cysts
2. Hatching
3. Active young
4. Naupliar stages
5. Juveniles
6. Adults
Growth And Development
In the cyst stage, Brine Shrimp do not feed, they live off reserves stored in the cysts.
Wild Brine shrimp eat planktonic algae. Cultured, or grown, Brine shrimp can be fed yeast, flour, soybean powder or egg yolk.
How Brine Shrimp Obtain Energy?
Brine shrimp prefer shallow salt waters, but can adapt to drying saltwater ponds. They control how much salt to let into their body. They can also live in seasonal ponds escape predators that cannot adapt. In addition, they have a fast reproductive cycle to keep population going. Their color adapts depending on the salt concentration in the water.
How do Brine Shrimp respond to their environment?
The Brine shrimps body is divided into 3 main parts, the head, the thorax, and the abdomen. The exoskeleton covers the entire body, which is made of chitin,this is where the muscles are located. The nervous system consists of the brain and the local nerves. Brine shrimp do not have spines and have 3 eyes.

Change Over Time
The Brine shrimp have developed abilities to control the amount of salt ingested. They are also very strong adapters. It is believed that many years ago the Brine shrimp had only 1 eye.
