Where are the largest ostracods found?
G. australis and G. danae are only known from the Southwestern Pacific and Western Indian Ocean, respectively. Gigantocypris have been reported at depths between 150 and 3,500 m (490–11,480 ft). They are typically found from 600 to 2,300 m (2,000–7,500 ft).

What is a giant ostracod?
Meet the giant ostracod Since they look like a shrimp inside of a seed pod, ostracods are sometimes called seed shrimp. Their bodies are hinged like a clam’s, and they can disappear into their pods with only their antennae showing. The giant ostracod swims by rowing its antennae like oars.
Where are ostracods found?
Ostracods are found in almost every aquatic habitat, even some very small and isolated places such as the tiny pools of water in bromeliads growing on trees. Some species have a global distribution and are found from the subarctic to the tropics. Their distribution in part is due to their dispersal abilities.
Do ostracods lay eggs?
In most species, eggs are either laid directly into the water or are attached to vegetation or another surface. In some species, the eggs are brooded inside the shell. The eggs hatch into nauplius larvae which already have a hard shell. Many freshwater ostracods reproduce asexually by cloning themsleves.
Do ostracods move?
Movement: Ostracods propel themselves through the water by using antennae and movement of numerous appendages, which are located in the gap between two valves.
How did seed shrimp get into my aquarium?
Seed shrimp are minuscule crustaceans that are mostly deemed as pests and may infest your aquarium if they are introduced by accident. These crustaceans may find their way to your tank with an aquatic plant or old gravel.
What fish eats ostracods?
Yes a betta is a good choice for ostracods. Their hard shell make them hard to eat-cories and tetras didnt touch them(or at least spit them back out).
Where can Gigantocypris be found in the world?
Gigantocypris are ubiquitous in open oceans around the world, ranging from tropical to polar regions. Although locally abundant, the distributions of the individual species are often not well known. G. dracontovalis is found worldwide, mostly deeper than the other species.
Why are the eyes of a Gigantocypris so important?
Their eyes are the most elaborate known from ostracods, and are better at gathering light than the eyes of any other animal (although the resolution of the image produced by the eyes is likely poor). It is thought that Gigantocypris use them to find bioluminescent prey animals.
What kind of antennae does a Gigantocypris have?
Gigantocypris swim by “rowing” with two featherlike antennae, each with nine long setae. Another pair of long antennae, believed to be used for sensing, extend out in front of the animal when swimming. Both their swimming and sensing antennae can be retracted into the globular carapace through its slit.
Where is the brood pouch located in a Gigantocypris?
The female Gigantocypris has a brood pouch, located inside the carapace, in which the eggs and embryos develop. When “born”, the young resemble miniature adults. Adult males are uncommon compared to adult females. ITIS and the World Register of Marine Species recognize six valid species in the genus Gigantocypris.
