Mandrake the Magician is a syndicated  newspaper comic strip, created by Lee Falk  before he created The Phantom.[1][2] Mandrake  began publication on June 11, 1934. Phil Davis soon took over as the strip's illustrator, while Falk continued to script. The strip was distributed by King Features Syndicate.[3] 

Mandrake, along with the Phantom Magician in Mel Graff's The Adventures of Patsy, is regarded as the first superhero of comics by comics historians such as Don Markstein, who writes, "Some people say Mandrake the Magician, who started in 1934, was comics' first superhero."[1][4][5][6]
Davis worked on the strip until his death in 1964, when Falk recruited artist Fred Fredericks.[3] With Falk's death in 1999, Fredericks became both writer and artist. The Sunday-newspaper Mandrake strip ended December 29, 2002. The daily newspaper strip ended mid-story on July 6, 2013, when Fred Fredericks retired, and a reprint of Pursuit of the Cobra (D220) from 1995 began July 8, 2013.

Color patterns vary, with only dark or colored shells or no stripes. They are typically found attached to objects, surfaces, or each other by threads underneath the shells. Although similar in appearance to the quagga mussel, the two species can be easily distinguished. When placed on a surface zebra mussels are stable on their flattened underside while quagga mussels, lacking a flat underside, will fall over.

Die Harnischwelse (Loricariidae) sind eine in Mittel- und Südamerika vorkommende Familie  der Ordnung der Welsartigen. Mit mehr als 80 Gattungen, über 820 beschriebenen und geschätzt 700 bis heute unbeschriebenen Arten sind sie die artenreichste Familie der Welsartigen und eine der artenreichsten Fischfamilien überhaupt.

Les Loricariidés (Loricariidae) sont la plus grande famille de poissons-chats (ordre des Siluriformes), avec 1 000[1] espèces connues et de nouvelles espèces décrites chaque année. Les Loricariidés proviennent des eaux douces du Costa Rica, du Panama, et des zones tropicales et subtropicales d'Amérique du Sud. On connaît des Loricariidés dans toutes les eaux douces du Panama à l'Argentine. Ces poissons sont connus pour leur ventouse buccale, et les plaques osseuses couvrant leur corps. Plusieurs genres sont vendus sous le nom de plécos, notamment le Pléco commun, et sont très populaires en aquariophilie. Plusieurs espèces sont connues pour produire des sons de stridulation grâce à leurs épines pectorales[2].

The L-number system is a semi-scientific classification system of catfish based on photographs of shipments of tropical catfish of the family Loricariidae published by the German aquarium magazine DATZ (Die Aquarien- und Terrarienzeitschrift (The Aquarium and Terrarium Magazine)). The first L-number was published in 1988.

Baryancistrus xanthellus (L018, L081, L085, L177, LDA060) er en art av harniskmaller i gruppen Ancistrini. Det er en bunnlevende ferskvannsfisk som finnes i Rio Xingu i Amazonas-vassdraget. Den blir opptil 29,7 cm lang SL[1]. Baryancistrus xanthellus er på grunn av sitt spesielle utseende en populær akvariefisk, og har fram til arten ble beskrevet  i 2011 gått under forskjellige L-numre, samt det engelske populærnavnet «gold nugget» eller «golden nugget» i akvariehandelen.

Odontodes, or dermal teeth, are hard structures found on the external surfaces of animals or near internal openings. They consist of a soft pulp cavity surrounded by dentine and covered by a mineralised substance such as enamel, a structure similar to that of teeth.[1] They generally do not have the same function as teeth, and are not replaced the same way teeth are in most fish.[2] In some animals (notably catfish), the presence or size of odontodes can be used in determining the sex.[3]

Hypostomus asperatus[1] is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Tocantins River basin. The species reaches 22.9 cm (9 inches) in standard length and is believed to be a facultative air-breather.[2]

Hypostomus subcarinatus is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the coastal drainage basins of eastern Brazil, including the São Francisco River basin. The species reaches 31 cm (12.2 inches) in total length  and is believed to be a facultative air-breather.[1] Although originally described in 1855, no verifiable scientific record of the species was made until a 2014 survey of an urban lake in downtown Belo Horizonte in the state of Minas Gerais collected seven specimens that were later recognized as Hypostomus subcarinatus, leading to a redescription of the species in 2019.[2]
