- Harmless phytoplankton grazers and are what I believe to be the best food source when trying to rear shrimp larvae as this group does not crawl the glass or sand and remains in mid-water which makes them available to free swimming, plankton larvae as a food source. I find these copepods in huge swarms during the day out on the reef's kelp beds, making collection of them very easy. I believe this family of copepods is available for purchase.
(with eggs) (without eggs)
Calanoid Family - Compared to other copepod species, these can appear quite large and are a very important food source for many fish. The small copepod shown below in the first photo is an adult Cyclopoida species as a size reference.

(An amphipod) - Can be difficult to identify as they resemble Isopods.
- ( Iso = Greek for "uniform or the same" Podos = Greek for "foot" ) Some species of this family group are parasitic / predatory. Any large specimens should be investigated. Additional Links - Parasitic Isopods
The Cirolanid family
of Isopods, Some Cirolanid species are obligate parasites, other species are strictly scavengers, and some are a combination of both. The vast majority of Cirolanids seen in the aquarium hobby seem to be obligate parasites of fish.
An Anthurid Isopod
- Carrying its young. Most likely a predator of other small animals.
The Tanaidaceans - Some are harmless grazers and others appear to be more predatory.
- Commonly called Seed Shrimp. A crustacean, and some are quite reminiscent of clams in their general shape. Most are considered to be detritivores. Extremely small animals and are usualy only seen when they swim to a new location.
The Swarmers - The majority of what appears to be very small worms swimming out in the open will in fact turn out to be a specialized worm segment whose sole purpose is to get out into the currents and release its payload of eggs or sperm. For more information on these, please see the worm's hitch hiker page.

A swarming Phylodocid found within my aquarium at night. It is less than 1 mm in length but still visible as being a worm.
A Syllid Epitoke which was formed at the posterior end of a worm which then breaks off and swims away with the eggs it is tasked with to carry and release into the drifting plankton. The eggs are the green spheres shown above.
The LARVAE - There are multitudes of species within the ocean that release their eggs / young to drift and feed with the oceans currents, only to drop out and settle down into new territory. I will post what each specimen is most likely to be, (thanks Dr. Ron) when possible.
