Symbiotic Relationship Between Butterfly Fish and Coral & by Noelle Stone on Prezi
Indo-Pacific coral reefs are home to over species of hard corals (also corals depend on the grazing by certain fishes for reproductive success. Chevron butterflyfish (Chaetodon trifascialis) feeds exclusively on Acropora hyacinthus. Fish from the butterfly family are among the most beautiful and colorful reef fish. They reproduce by releasing eggs and sperm into a body of water. in a permanent spousal relationship, on and in front of the coral reef, up to a depth of 12m. Predator-prey because the butterfly fish eats the coral polyps. 7. How would you classify the relationship between the coral polyps and the plankton?.
Field observations revealed that all bites taken on benthic substrates by C.
Alternatively, the energetic demands of C. Neither dietary specialization nor geographic range accounts for interspecific variation in abundance of coral reef butterflyfishes at Lord Howe Island, while much more work on the foraging behavior and population dynamics of C.
Chaetodontidae, corallivore, disturbance, ecological function, endemism, schooling, selectivity, specialization Introduction Endemic species are an important component of biodiversity but are also considered to be disproportionately affected by disturbances, and more likely to go extinct because relatively moderate disturbances can simultaneously affect the entire population McKinney ; Gaston ; Roberts et al.
Moreover, geographic range is often correlated with abundance e.

This double jeopardy of extinction risk may also be further compounded if small range size is associated with other traits e. Ecological specialization the extent to which species specialize in their use of prey or habitat resources is increasingly considered alongside population size and geographical range as a key determinant of extinction risk e.
An alternative explanation is that extinction filtering promotes persistence of species with compensatory relationships between range size, ecological specialization and population size that reduce the risk of extinction e. For instance, shading can reduce rates of photosynthesis, abrasion can result in tissue damage at contact points, and attenuation of sediments and associated microbial communities can increase rates of coral disease Contact with some seaweeds can also lead to tissue mortality due to the allelopathic chemicals within the thalli Thus, shifts from coral- to seaweed-dominated benthic communities will have dramatic flow-on effects for reef associated organisms, such as fishes, many of which rely on scleractinian corals for survival.
While the habitat requirements of coral reef fishes are highly variable, the abundance and distributions of many species are closely related with the spatial structure of reef substrata, particularly scleractinian coral abundance 19structural complexity 2021 and overall community composition 22 Such associations arise as these corals provide essential shelter 24access to food resources 25and recruitment cues 26 for many fishes.
Abundance, diversity, and feeding behavior of coral reef butterflyfishes at Lord Howe Island
Chaetodontidaeare a ubiquitous and much studied component of coral reef communities worldwide While these fishes exhibit a variety of dietary strategies 28they are best known for the high degree of opportunistic and obligate corallivory found within this family, especially within the genus Chaetodon 25 Not surprisingly, associations between these butterflyfishes and scleractinian corals are often particularly strong 30with significant declines in abundance observed following the loss of scleractinian corals 31 Many corallivorous butterflyfishes are highly selective between available prey 33 Therefore, given their abundance and direct or indirect reliance on corals for food, the foraging patterns and behavior of these fishes may have some influence on the fitness and distribution of corals within their habitats Understanding these patterns is vital given global declines in coral cover and increases in seaweed abundance.
However, the responses of butterflyfish to seaweed, in particular whether seaweed affects resource selection, are poorly understood. They are also active at night, and they feed mainly on coral stone polyps, sea anemones, multi-bristled worms, sponges, and algae.
The Crown Butterfly Fish This is a small fish, up to 12cm in length. It is active during the day, lives in a permanent spousal relationship, on and in front of the coral reef, up to a depth of 12m. Its eyes are camouflaged by an eye strip that crosses the pupil, and it has a black stain on its forehead.
It gets its name from the large red stain on the rear section of its body. The rest of its body is colored in yellow shades with dashed brown stripes, and it has a yellow tail fin with a red stripe on its edge. It feeds on crustaceans and coral polyps.
