Where?

The depths at which the deep sea shrimp can be found vary with the different seasons. They can be found anywhere between 9 m and 1450 m, but usually they live between 50 m and 500 m. On average the shrimp can live up to 4 and a half years, but usually live up to 3 and a half years, other scientists say that the females can live up to 8 years. The shrimp can reach a size ranging between 23.13 mm and 24.43 mm when reaching maturity.

Reproduction of the deep sea shrimp

The deep sea shrimp is hermaphroditic. This means that each deep sea shrimp is first born as a male, then passes through an intersexual phase and after the intersexual phase they become female.  When the female is carrying eggs it while migrate from the deep sea zones to more shallow waters. The main cause of mortality is attributed to fish predators and fishing.

What do sea shrimp eat?

The deep sea shrimp’s diet may vary, this mainly depends on where the shrimp is living. Here are some of the organisms/animals found in the diet of the shrimp: Mysida (small crustaceans), porifera (sponges), plankton, crabs and tiny clams. Cannibalism has also been observed with these crustaceans. Another species of deep sea shrimp called
Hirondellea Gigas, which has been found at a depth of 35.820 feet in the Mariana Trench has another feeding habit. According to National Geographic it feeds itself with small wood particles, which have sunk to the deeper parts of the ocean. A sunken wooden ship for example would be a true feast for these little animals.
