These groups have adaptations specifically for life as plankton. Lantern fish range in size from around 2 cm to 30 cm and they mostly feed on plankton, small crustaceans and squid. There are 246 species of lantern fish in 33 genera that can be found in oceans all around the world. This nomadic, floating existence also allows them to colonize new habitats. The small size of the species makes them a popular choice for consumption. At these early stages, they feed on zooplankton. In addition to the tiny animals that spend their lives floating in the water, there are many other aquatic animals, such as crabs, shrimp, sea stars, snails, clams, and fish, that spend the first stages of life as plankton. ![]() These great blooms of phytoplankton feed the zooplankton, which are what make our waters able to support large commercial and recreational fisheries, as well as populations of whales, dolphins, seals, and sea birds. When water temperatures rise and sunlight increases, the phytoplankton increase, and then the copepods that eat them grow in number, too. Off our coasts here in New England and the Mid Atlantic, this often happens in the spring. When conditions are right, copepods and other zooplankton can bloom in such numbers that the water becomes cloudy. Q: What do lantern fish eat A: Lantern fish are known to be opportunistic predators, feeding on a wide variety of prey depending on their size and location. It helps, then, that sometimes zooplankton are found in vast numbers called “blooms.” As you might imagine, right whales have to eat a lot of zooplankton. One of the largest and rarest animals alive, the right whale, filter-feeds on copepods. Do Copepods Eat Bacteria Yes, some copepod species may eat the bacteria they find on detritus, meaning dead organisms, parts of dead organisms, or feces. Anchovies and other planktivores (plankton-eaters) are prey for bigger animals, like tuna, sharks, marine mammals, and seabirds.īut sometimes there’s no middle level. Small planktonic carnivorous and omnivorous copepods may eat the following: Anchovy larvae (small fish) Chaetognaths (it’s the main food for Candacia bradyi copepods) Artemia nauplii. Students observing copepod samples on research cruise.įish such as anchovies cruise through the water with their mouths wide open, filtering copepods and other zooplankton from the water. ![]()
