Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
Girella zebra, also known as zebrafish or stripey bream, is a species of marine ray-finned fish, a sea chub in the family Kyphosidae. It lives in the Indo-Pacific , where it is endemic to the coastal waters of the southern parts of Australia .
The zebrafish (Danio rerio) is a freshwater fish belonging to the minnow family of the order Cypriniformes.Native to South Asia, [2] it is a popular aquarium fish, frequently sold under the trade name zebra danio [3] (and thus often called a "tropical fish" although it is both tropical and subtropical).
It is a herbivorous species eating red, brown, and green algae. Juveniles behave as cleaner fish for the opaleye (Girella nigricans) and shiner perch {Cymatogaster aggregata) They are often form mixed schools with halfmoon (Medianluna californiensis) Opaleye, and Pacific sergeant major (Abudefduf troschelii). At night this diurnal species hides ...
Typical zebra hunting groups consist of 10–25 hyenas, [17] though there is one record of a hyena killing an adult zebra unaided. [18] During a chase, zebras typically move in tight bunches, with the hyenas pursuing behind in a crescent formation. Chases are usually relatively slow, with an average speed of 15–30 km/h.
The convict cichlid (Amatitlania nigrofasciata) is a fish species from the family Cichlidae, native to Central America, [3] also known as the zebra cichlid. [4] Convict cichlids are popular aquarium fish [ 3 ] and have also been the subject of numerous studies on fish behaviour.
This species of fish has been found inshore in and around coral reefs and it can also be found in areas with sand and mud bottoms, possibly associated with gorgonians. [4] The maximum reported depth is 69 m (226 ft). [5] It is ovoviviparous, the male carries the eggs in a brood pouch that is situated under the tail. [4]
Grévy's zebra populations are estimated at less than 2,000 mature individuals, but they are stable. Mountain zebras number near 35,000 individuals and their population appears to be increasing. Plains zebra are estimated to number 150,000–250,000 with a decreasing population trend. Human intervention has fragmented zebra ranges and populations.
