How Big Do Sea Monkeys Get? (9 Clear Facts)

Sea monkeys are a hybrid species of brine shrimp, created in 1957 by Harold Von Braunhut, who discovered that brine shrimp could be induced to remain in a state of suspended animation for extended periods of time. The original name for them was “Instant Life”, not “Sea-Monkeys”, and they were marketed as being able to be revived instantly by adding water, hence the name. According to their inventor, Harold von Braunhut, Sea Monkey eggs stay dormant for years until added to water, at which point they hatch and resemble tiny versions of their parents.

The newly-shed skin is very soft and sensitive to the touch. This is why the fish are able to feel pain when they’re handled. Sea monkeys breed once every two years during the rainy season in their native habitat areas of Southeast Asia, Mexico and South America.

Afterwards, the adults pair up and care for between one and three young sea monkeys at a time. The parents will also protect themselves from predators by forming a protective circle around their young ones.

In captivity, sea monkey reproduction is controlled by temperature, light and food availability. Temperature must be between 72-78 degrees Fahrenheit (22-25 degrees Celsius), to allow for regular egg production and hatching, while dark and dim lighting conditions are needed to allow for normal growth.

Sea monkeys can also reproduce under stressful conditions such as disease or overcrowding.

The main source of food for sea monkeys is algae called polyps. Polyps supply algae to the young sea monkeys and they must eat them in order to develop into adult sea monkeys.

Sea monkeys have no teeth but use their mouth to grab on to polyps with their tentacles. The polyps will then be carried back into the sea monkey’s mouth where it will be digested through its gills.
