The word zooplankton is derived from Ancient Greek: ζῷον, romanized: zôion, lit. 'animal'; and πλᾰγκτός, planktós, 'wanderer; drifter'. [4] Zooplankton is a categorization spanning a range of organism sizes including small protozoans and large metazoans.

Fish larvae are part of the zooplankton that eat smaller plankton, while fish eggs carry their own food supply. Both eggs and larvae are themselves eaten by larger animals. [2] [3] Fish can produce high numbers of eggs which are often released into the open water column. Fish eggs typically have a diameter of about 1 millimetre (0.039 in).
Marine biogenic calcification is the production of calcium carbonate by organisms in the global ocean.. Marine biogenic calcification is the biologically mediated process by which marine organisms produce and deposit calcium carbonate minerals to form skeletal structures or hard tissues.
The boa in the U.K., a 6-foot, 13-year-old Brazilian Rainbow Boa named Ronaldo, gave birth last week after having no contact with any other snakes for at least nine years, according to the City of ...
Early stage larvae swim poorly, but later stage larvae swim better and cease to be planktonic as they grow into juveniles. Fish larvae are part of the zooplankton that eat smaller plankton, while fish eggs carry their own food supply. Both eggs and larvae are themselves eaten by larger animals. [1] [2]
A planktivore is an aquatic organism that feeds on planktonic food, including zooplankton and phytoplankton. [1] [2] Planktivorous organisms encompass a range of some of the planet's smallest to largest multicellular animals in both the present day and in the past billion years; basking sharks and copepods are just two examples of giant and microscopic organisms that feed upon plankton.
The global biomass of gelatinous zooplankton (sometimes referred to as jelly‐C) within the upper 200 m of the ocean amounts to 0.038 Pg C. [21] Calculations for mesozooplankton (200 μm to 2 cm) suggest about 0.20 Pg C. [22] The short life span of most gelatinous zooplankton, from weeks up to 2 to 12 months, [23] [24] suggests biomass ...
