Paedophagy
Paedophagy (literally meaning the "consumption of children") in its general form is the feeding behaviour of fish or other animals whose diet is partially, or primarily the eggs or larvae of other animals. However, P. H. Greenwood, who was the first to describe paedophagia, defines it to be a feeding behaviour evolved among cichlid fishes.Nshobo, M.(1991).Occasional egg-eating by the scale eater plecodus straeleni (cichlidae) of Lake Tanganyika in Africa. Environmental Biology of Fishes.31(2):207-212.Ribbink, A. (1997).Paedophagia among cichlid fishes of Lake Victoria and Lake Malawi.South African Journal of Science.93(11-12):509-512.Wilhelm, M."The disrupted feeding behaviour of a paedophagous haplochromine cichilid (Pisces).Behaviour.74:310-323. Location Paedophagy is found in fishes from Lake Victoria in Africa which in total has 200-300 species,Sturmbauer, C & Meyer, A.(1993).Mitochondrial Phylogeny of the Endemic Mouthbrooding Lineages of Cichlid Fishes from Lake Tanganyi ...

Cichlid
Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relative of cichlids is probably the convict blenny, and both families are classified in the 5th edition of ''Fishes of the World'' as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Many cichlids, particularly tilapia, are important food fishes, while others, such as the ''Cichla'' species, are valued game fish. The family also includes many popular freshwater aquariu ...

Caprichromis
''Caprichromis'' is a small genus of haplochromine cichlids endemic to Lake Malawi in East Africa. This genus contains noted paedophagous cichlids, specialising in the eating of eggs and fry of other cichlid species.

Plecodus Straeleni
''Plecodus straeleni'' is a species of cichlid fish that is endemic to Lake Tanganyika in East Africa. This species can reach a total length of . Like all species of ''Plecodus'', this fish is a scale-eater. Unlike other members of its genus, it has a distinctive striped pattern and closely resembles the harmless '' Neolamprologus sexfasciatus''. It uses this aggressive mimicry to be able to approach unsuspecting fish and rapidly take a mouthful of scales.Boileau; Cortesi; Egger; Muschick; Indermaur; Theis; Büscher; and Salzburger (2015). A complex mode of aggressive mimicry in a scale-eating cichlid fish. Biol Lett. 11(9): 20150521. It also resembles the larger '' Cyphotilapia'' and has been recorded swimming among their schools, but this may be protective rather than aggressive mimicry. Although it may attack the species it mimics, most victims are other species and under some circumstances it will feed on fish eggs.Nshombo, M. (1991). Occasional egg-eating by the scale-eat ...

Etroplus Maculatus
The orange chromide (''Pseudetroplus maculatus'') is a species of cichlid fish that is Endemism, endemic to freshwater and brackish water, brackish streams, lagoons and estuary, estuaries in southern India and Sri Lanka.Pethiyagoda, R., Maduwage, K. & Manamendra-Arachchi, K. (2014): Validation of the South Asian cichlid genus ''Pseudetroplus'' Bleeker (Pisces: Cichlidae). ''Zootaxa, 3838 (5): 595–600''. It is also known as pallathi (Malayalam: പള്ളത്തി) in Malayalam. The species is popular with fishkeeping hobbyists, and is kept frequently in aquariums. The species is part of the Family (biology), family Cichlidae and is included in subfamily Etroplinae. The orange chromide reaches a length of up to . Diet The species co-occurs throughout its range with the green chromide (''Etroplus suratensis'').

Mouthbrooder
Mouthbrooding, also known as oral incubation and buccal incubation, is the care given by some groups of animals to their offspring by holding them in the mouth of the parent for extended periods of time. Although mouthbrooding is performed by a variety of different animals, such as the Darwin's frog, fish are by far the most diverse mouthbrooders. Mouthbrooding has evolved independently in several different families of fish. Mouthbrooding behaviour Paternal mouthbrooders are species where the male looks after the eggs. Paternal mouthbrooders include the arowana, various mouthbrooding bettas and gouramies such as ''Betta pugnax'', and sea catfish such as ''Ariopsis felis''. Among cichlids, paternal mouthbrooding is relatively rare, but is found among some of the tilapiines, most notably the black-chin tilapia ''Sarotherodon melanotheron''. In the case of the maternal mouthbrooders, the female takes the eggs. Maternal mouthbrooders are found among both African and South American ci ...

Ichthyology
Ichthyology is the branch of zoology devoted to the study of fish, including bony fish ( Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish (Agnatha). According to FishBase, 33,400 species of fish had been described as of October 2016, with approximately 250 new species described each year. Etymology The word is derived from the Greek words ἰχθύς, ''ikhthus'', meaning "fish"; and λογία, ''logia'', meaning "to study". History The study of fish dates from the Upper Paleolithic Revolution (with the advent of "high culture"). The science of ichthyology was developed in several interconnecting epochs, each with various significant advancements. The study of fish receives its origins from humans' desire to feed, clothe, and equip themselves with useful implements. According to Michael Barton, a prominent ichthyologist and professor at Centre College, "the earliest ichthyologists were ''hunters and gatherers'' who had learned how to obtain the most use ...

A Modest Proposal
''A Modest Proposal For preventing the Children of Poor People From being a Burthen to Their Parents or Country, and For making them Beneficial to the Publick'', commonly referred to as ''A Modest Proposal'', is a Juvenalian satirical essay written and published anonymously by Jonathan Swift in 1729. The essay suggests that the impoverished Irish might ease their economic troubles by selling their children as food to rich gentlemen and ladies. This satirical hyperbole mocked heartless attitudes towards the poor, predominantly Irish Catholic (i.e., "Papists") as well as British policy towards the Irish in general. In English writing, the phrase "a modest proposal" is now conventionally an allusion to this style of straight-faced satire. Synopsis Swift's essay is widely held to be one of the greatest examples of sustained irony in the history of the English language. Much of its shock value derives from the fact that the first portion of the essay describes the plight of starvi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
