Sea Monkeys are a type of brine shrimp that are sold as novelty aquarium pets. The product was developed in the United States in 1957 by Harold von Braunhut and marketed as a fun and easy-to-care-for pet for children and adults alike.

Von Braunhut was inspired to create Sea Monkeys after discovering a bucket filled with brine shrimp in a pet store. He realized that these tiny creatures had the potential to be marketed as a unique and fascinating pet, and he began to experiment with different ways to package and sell them.

The first Sea Monkey kits were sold in the 1960s and quickly became popular among children and adults. The kits typically included a small tank, a packet of brine shrimp eggs, and instructions for hatching and caring for the creatures.

Over the years, Sea Monkeys have undergone several changes and improvements. Today, they are available in a variety of different kits, including ones that glow in the dark and ones that come with special accessories like castles and pirate ships.

Despite their popularity, Sea Monkeys have also been the subject of controversy. Some critics have accused the product of being a scam, arguing that the creatures are not actually monkeys and that the advertising is misleading. However, supporters of Sea Monkeys argue that they are a fun and educational pet that can teach children about science and biology.

Overall, the history of Sea Monkeys is a fascinating one that has captured the imaginations of generations of children and adults alike. Whether you love them or hate them, there is no denying that these tiny creatures have left a lasting mark on popular culture.

Biology of Sea Monkeys

Sea Monkeys, also known as Artemia NYOS, are a hybrid breed of brine shrimp that were first produced in 1957 by Harold von Braunhut, a mail-order marketer and inventor. These tiny creatures are known for their unique appearance and are often marketed as novelty pets for children.

Sea Monkeys are small, typically measuring between 0.2 and 0.5 inches in length. They have a transparent body and a long, forked tail, which they use to swim through the water. Their most distinctive feature is their crown-shaped head, which is covered in hair-like structures called cilia. These cilia are used to filter food particles from the water.

In the wild, Sea Monkeys are found in saltwater lakes and ponds around the world. They are able to survive in these harsh environments due to their unique ability to enter a state of suspended animation, known as cryptobiosis. During this state, their metabolism slows down to almost zero, allowing them to survive without food or water for extended periods of time.

Sea Monkeys are omnivores, feeding on a variety of small organisms, including algae, bacteria, and other microscopic creatures. They are also capable of reproducing asexually, with females producing eggs that hatch into fully-formed juveniles.

Overall, Sea Monkeys are fascinating creatures with a unique biology that has captured the imaginations of people around the world.

Breeding and Life Cycle

Sea monkeys are a type of brine shrimp that can be bred in captivity. Breeding sea monkeys is a simple process that requires minimal effort. To start breeding sea monkeys, one needs to purchase a sea monkey kit that contains eggs, water purifier, and food.

Once the kit is purchased, the first step is to add water to the tank. The water should be room temperature, between 70 F (21C) to 76 F (24C). The next step is to add the water purifier, which comes in sachet No 1. The entire contents of the sachet should be poured into the water, and stirred for 1 minute or until the powder has completely dissolved.

After the water purifier has been added, the next step is to add the eggs, which come in sachet No 2. The eggs should be sprinkled into the water and stirred gently. The eggs will hatch in 24 to 36 hours, and the newly hatched sea monkeys will be visible to the naked eye.

Sea monkeys have a life cycle of 6 months to 1 year, depending on environmental conditions. They grow quickly and can reach a size of up to 15mm in length. Sea monkeys are hermaphrodites, meaning they have both male and female reproductive organs. They can reproduce asexually or sexually, depending on the environmental conditions.

During the breeding process, sea monkeys require food to survive. The food, which comes in sachet No 3, should be added to the water once a week. The food contains a mixture of yeast, spirulina, and other nutrients that are essential for the growth and development of sea monkeys.

In conclusion, breeding sea monkeys is a simple process that requires minimal effort. With the right environmental conditions and food, sea monkeys can grow and reproduce quickly.

Sea Monkeys as Pets

Sea Monkeys are a popular choice for kids as they are easy to care for and provide a fun and educational experience. Here are some tips for setting up and caring for your Sea Monkeys as pets.

Setup and Care

Sea Monkeys require a small aquarium or tank with a capacity of at least 1 litre. The aquarium should be filled with dechlorinated water and a Sea Monkey kit should be added to it. The kit usually contains eggs, food, and instructions. The aquarium should be placed in a well-lit area but away from direct sunlight and drafts.

Sea Monkeys are sensitive to temperature changes, so it is important to maintain a constant temperature between 20°C and 27°C. A small heater or thermometer can be used to regulate the temperature.


Sea Monkeys are filter feeders and require a constant supply of food. The kit usually comes with a food packet that should be added to the aquarium every 5-7 days. In addition, they can be fed with liquid or powdered food that can be purchased from pet stores. Overfeeding should be avoided as it can cause the water to become cloudy and oxygen levels to drop.

Common Issues and Solutions

One common issue with Sea Monkeys is the growth of algae in the aquarium. Algae growth can be controlled by reducing the amount of light the aquarium receives or by adding an algae control product.

Another issue is the death of Sea Monkeys due to poor water quality. It is important to regularly clean the aquarium and replace the water every 2-3 weeks. A water conditioner can be used to remove any chlorine or other chemicals from the water.

In summary, Sea Monkeys are a fun and educational pet for kids. They require a small aquarium, constant temperature, and regular feeding. With proper care, they can live up to 2 years.

Scientific Research and Sea Monkeys

Sea monkeys, also known as brine shrimp, have been the subject of scientific research for many years. Researchers have studied these tiny creatures to learn more about their unique characteristics and behavior.

One area of research has focused on the ability of sea monkeys to stir the sea. A study conducted by M. Wilhelmus and J.O. Dabiri from Caltech proposed that the tiny eddies generated by brine shrimp migrating to and from the ocean surface daily might mix the upper layers of the seas as effectively as winds and tides do. This research suggests that sea monkeys have a significant impact on ocean currents and could play a crucial role in the ocean’s ecosystem.

Another area of research has focused on the reproductive habits of sea monkeys. A study found that shrimp-like creatures on the South Coast of England have 70% less sperm than they did 30 years ago, which could have implications for the future of the species.

Despite their small size, sea monkeys have also been used in scientific research as a model organism for studying genetics and developmental biology. Their transparent bodies make them ideal for observing the development of organs and tissues.

Overall, sea monkeys continue to be a fascinating subject of scientific research, and researchers are constantly discovering new information about these tiny creatures.
