Found in coral reefs are colorful damselfishes in large schools, large parrotfishes
whose hues can range from dark blue to yellow to grey in eye-popping patterns.
For example, in 1985, the total biomass was estimated at 10,025 t, and excavators (large-bodied parrotfishes
The topics are pair formation in coral reef fishes: an ecological perspectives; the ecosystem roles of parrotfishes
on tropical reefs; limits to understanding and managing outbreaks of crown-of-thorns starfish (Acanthaster spp.
are very important to coral reef health because they eat the algae that would otherwise overwhelm young corals on reefs recovering from natural disturbances.
We saw increasing numbers of mid-level predators - such as snappers - and a reduction in the number of herbivores such as parrotfishes
, which are very important to coral reef health because they eat the algae that would otherwise overwhelm young corals on reefs recovering from natural disturbances," Meekan said.
A phylogenetic study of the parrotfishes
family Scaridae (Pisces: Labroidei) with a revision of genera.
Both sexes are illustrated for species that exhibit sexual dichromatism, such as wrasses, parrotfishes
, and triggerfishes.
More than two thirds of the assemblage by NISP is made up of just four families: parrotfishes
(l) (Scaridae), surgeonfishes (Acanthuridae), wrasses (Labridae), and emperors (Lethrinidae).
Fish pots targeted spiny lobsters, grunts, boxfishes, queen triggerfishes, and parrotfishes
, whereas lobster traps landed mainly spiny lobsters.
Effects of fishing on sex-changing Caribbean parrotfishes
On a healthy reef, grazing herbivores such as turtles and parrotfishes
, along with other fishes, control the growth of tiny photosynthetic algae, the starting point of coral reefs' food web.
, family Scaridae, are characterized as specialized perciform fishes that closely associate with reefs and are primarily tropical in distribution (Schultz 1958, 1969 and Nelson 1994).
