Ostracods are found commonly as fossils and are still living today in all aquatic habitats, from the deep sea to small temporary ponds. A few species can be found crawling around on land in moist habitats, such as wetland mosses.

How old are ostracods?
The first fossil ostracods are recognized from rocks of the Ordovician Period, 485 to 443 million years ago.
Do ostracods have eyes?
The primary sense of ostracods is likely touch, as they have several sensitive hairs on their bodies and appendages. However, they do possess a single naupliar eye, and, in some cases, a pair of compound eyes, as well.
What do ostracods do?
There are carnivores/predators, herbivores, detritivores, and scavengers but ostracods are generally characterized as omnivorous scavengers. They eat tiny organisms like algae, diatoms, bacteria, molds, and pieces of organic detritus that are present in the water or on vegetation.
How do ostracods grow?
They grow by moulting up to nine growth stages (instars). Because of this sexual dimorphism and the ontogenetic variations of ostracods great care must be taken with taxonomy, as a single species may have a series of juvenile stages as well as two adult morphotypes.
How do I get rid of ostracods?
About the only way to get rid of them is to keep fish or other critters that eat every one that hatches and keep them for about 3 years. I think that by three years all the eggs will have hatched. Another way might be to remove all the inside silicone , scrub thoroughly, and re-silicone the tank.
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.
What is special about the ostracods in the Caribbean?
The Caribbean is home to a special species of Ostracods, the “blue tears” or “blue sand” Ostracods, who generate blue light as part of their monthly mating display. Every month after the full moon, the ocean lights up in a brilliant bioluminescent display that can only be compared to a beautiful starry night.
Are ostracods planktonic?
Ostracoda represent small, often planktonic, crustaceans from marine, brackish, and freshwaters and comprise 62 000 fossil and recent species.
Are ostracods harmful?
I would not worry too much about ostracods, they mainly eat vegetable matter and are no threat to adult axolotls. They are most likely to have come in with daphnia. They are good at removing dead leaves without harming live ones.
Where can ostracods be found?
Ostracods are found commonly as fossils and are still living today in all aquatic habitats, from the deep sea to small temporary ponds. A few species can be found crawling around on land in moist habitats, such as wetland mosses.
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.
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).
Do seed shrimp have eyes?
They have a single eye. The body of a Seed Shrimp is protected by two shells that form its carapace. The carapace resembles a seed, so they are called Seed Shrimp.
What do freshwater ostracods eat?
Diet. The freshwater ostracod Heterocypris incongruens grazing algae on a fallen leaf. Most free-living ostracods are considered to feed on algae and organic detritus, but some ostracods are omnivores, predators and scavengers.
Why do ostracods use light?
Luminescent ostracods can use light for predator defense and for courtship displays. Those that use light to surprise and deter predators emit light when threatened or even when swallowed, causing predators to spit them out in order to avoid being spotted by their own predators.
