[5] [6] Corallivorous fish come from 11 different families. [5] 39 species are obligate corallivores. [5] Butterflyfish have a wide range of adaptations that facilitate coral consumption. Some butterflyfish have long mouth that they use like forceps to pluck off individual coral polyps and some use their teeth to scrape off coral tissue. [2]
Forage fish: Forage fish occupy central positions in the ocean food webs. The organisms it eats are at a lower trophic level, and the organisms that eat it are at a higher trophic level. Forage fish occupy middle levels in the food web, serving as a dominant prey to higher level fish, seabirds and mammals. [28] Predator fish; Ground fish
General characteristics of a large marine ecosystem (Gulf of Alaska). Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal ...
While amphibians continued to feed on fish and later insects, reptiles began exploring two new food types, other tetrapods (carnivory), and later, plants (herbivory). Carnivory was a natural transition from insectivory for medium and large tetrapods, requiring minimal adaptation (in contrast, a complex set of adaptations was necessary for ...
General characteristics of a large marine ecosystem (Gulf of Alaska) Killer whales (orcas) are highly visible marine apex predators that hunt many large species. But most biological activity in the ocean takes place with microscopic marine organisms that cannot be seen individually with the naked eye, such as marine bacteria and phytoplankton.
A new study finds that playful people are better equipped for navigating tough times — something researchers call "lemonading."
Resting small fish are still vulnerable to attack by crevice predators, so many fish, such as triggerfish, squeeze into a small hiding place and wedge themselves by erecting their spines. [ 2 ] As an example of the adaptations made by reef fish, the yellow tang is a herbivore which feeds on benthic turf algae.
From January 2008 to December 2012, if you bought shares in companies when Albert A. Gore joined the board, and sold them when he left, you would have a 167.1 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
