What is the biggest copepod?
Copepods are tiny oceanic crustaceans with prodigious appetites. Most copepods are 0.5 to 2 mm (0.02 to 0.08 inch) long. The largest species, Pennella balaenopterae, which is parasitic on the fin whale, grows to a length of 32 cm (about 13 inches).
What makes copepods unique?
Many copepods have two propulsion systems: they swim by vibrating the feeding appendages, while the swimming legs are used exclusively for short-lasting escape jumps. Altogether, these features allow for unusually forceful and fast escape responses in pelagic copepods.
What is the difference between copepods and phytoplankton?
Zooplankton feed on microscopic plant-like organisms called phytoplankton, which get their energy from the sun. Tiny crustacean zooplankton called “copepods” are like cows of the sea, eating the phytoplankton and converting the sun’s energy into food for higher trophic levels in the food web.
How do I identify copepods?
Distinguishing characteristics Copepods have short cylindrical bodies clearly divided into a number of segments. The head section is usually rounded and bears prominent, often very long antennae, which when held away from the body, serve to slow sinking rate. There are usually 9 free trunk segments.
Will crabs eat copepods?

Do copepods eat each other?
Some species are actually quite predaceous and will even eat each other if other forms of nutrition are scarce. Rotifers in turn can be a potential food source for at least some species of copepod, if nothing else they’ll either coexist or function as a food source for the pods.
Do copepods eat phytoplankton?
Pelagic copepods such as the Tangerine, Acartia, and Pseudodiaptomus eat phytoplankton (free-swimming phytoplankton). As a general rule, the brown microalgae (T. Isochrysis galbana) are better than the greens (nannochloropsis).
Where can I find copepods?
Copepods are sometimes found in public main water supplies , especially systems where the water is not mechanically filtered, such as New York City, Boston, and San Francisco. This is not usually a problem in treated water supplies.
How do copepods reproduce?
Reproduction in Copepods. Similar to criters such as bacteria, Copepods use both processes of mitosis and meiosis to reproduce, depending on their size and ethnicity. Small plankton species use asexual reproduction because of their extremely small size they have no real internal organ, they can make their own eggs.
