Which one is bigger?

[SharkBait]

As per above

[Tanzy]

On the average, copepods will be larger as they can grow to 2.5mm depending on species whereas rotifers will be at biggest only about 0.2mm.

Sorry to interrupt. Tanzy, is there a site that shows the sizes of BBS, rotifiers, planktons, cyclops and other such stuff? Thanks in advance.

Non that I know of. Search the internet or ask Bawater.

There are many sites which go into details -only thing is that its species related e.g one for rotifers,one for bbs,cyclops etc etc.

most of them measure the size in microns (1000 microns is 1mm).

phytoplankton come in a range of sizes(2microns-160microns) -so unless you specify the actual micro algae strain can't give u the size.

Rotifers - 100-150microns (L strain)

BBS - on average 350-400microns or even up to 600microns.

(again there are different strains of bbs,e.g San Francisco bay ones are smaller & higher nutrition but also more expensive due to limited quantity harvested)

cyclops - 800microns (part of the copepod family)

Assortment of Pods - 1000microns onwards

(wild zooplankton mixture range in sizes from 100-1000microns)
