Dinoflagellates are mostly marine plankton, but they are also common in freshwater habitats. Their populations vary with sea surface temperature, salinity, and depth. Many dinoflagellates are photosynthetic, but a large fraction of these are in fact mixotrophic, combining photosynthesis with ingestion of prey (phagotrophy and myzocytosis). [6] [7]
Some of the largest plankton are krill and feed the largest of animals, baleen whales. My first foray into the scientific world was a job sexing Jassa falcata (a tiny amphipod) under a microscope.
Zooplankton feed on bacterioplankton, phytoplankton, other zooplankton (sometimes cannibalistically), detritus (or marine snow) and even nektonic organisms. As a result, zooplankton are primarily found in surface waters where food resources (phytoplankton or other zooplankton) are abundant. Zooplankton can also act as a disease reservoir.
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.
Well this isn’t creepy, but it is funny when bioluminescent plankton gets sucked up into the marine heads and you get to pee on glowy water. I spent 4 years sailing full time after college and I ...
Both day and night, its progress was very slow, around 1.5–2.1 km/h (0.81–1.13 kn). This pattern of vertical migration is seen in many marine animals as they track the movement of plankton in the water column. [23] The shark captured in March 2009 was reportedly netted at a depth of 200 m (660 ft). [citation needed]
What they look like: Chiggers, a type of small mite, typically leave clusters of bites. If you have chigger bites, they'll be small, red and likely quite itchy.Chigger bites may also look like ...
