Synodontis schoutedeni

Synodontis schoutedeni, known as [1] the yellow marbled Synodontis,[2] is a species of upside-down catfish native to the Congo Basin of the Democratic Republic of the Congo and the Republic of the Congo.[1] It was first described by Belgian ichthyologist Lore Rose David in 1936, based upon a holotype discovered in Basongo, in what is now the Democratic Republic of the Congo.[1] The specific name "schoutedeni" is named after the Belgian zoologist Henri Schouteden.[3]

Description

The fish is cream-colored with a brownish-mauve marbled pattern on the head, body, and adipose fin.[3] Other fins are clear with dark spots.[3] The color patterns on the fish tend to become more pronounced in older individuals.[2]

Like other members of the genus, this fish has a humeral process, which is a bony spike that is attached to a hardened head cap on the fish and can be seen extending beyond the gill opening.[2] The first ray of the dorsal fin and the pectoral fins have a hardened first ray which is serrated.[2] The caudal fin is forked.[2] It has short, cone-shaped teeth in the upper jaw.[2] In the lower jaw, the teeth are s-shaped and movable.[2] The fish has one pair of long, dark-colored maxillary barbels, that reach as far as the base of the ventral fins, and two pairs of mandibular barbels that are often branched.[2][3] The pectoral fin spine is finely serrated on the outer edge, and heavily serrated on the inner edge.[3]

This species grows to a standard length of 12.7 centimetres (5.0 in) although specimens up to 17.1 centimetres (6.7 in) total length have been recorded in the wild.[1][2]

Habitat

In the wild, the species inhabits tropical waters with a temperature range of 22 to 26 °C (72 to 79 °F), a pH of 6.0 – 7.5, and dH range of 4-15.[1] It has been found in the central Congo River basin and in Pool Malebo.[4] It is harvested for human consumption.[4]

gollark: An alternative to using CD or USB images for installation is to use the static version of the package manager Pacman, from within another Linux-based operating system. The user can mount their newly formatted drive partition, and use pacstrap (or Pacman with the appropriate command-line switch) to install base and additional packages with the mountpoint of the destination device as the root for its operations. This method is useful when installing Arch Linux onto USB flash drives, or onto a temporarily mounted device which belongs to another system. Regardless of the selected installation type, further actions need to be taken before the new system is ready for use, most notably by installing a bootloader and configuring the new system with a system name, network connection, language settings, and graphical user interface. The installation images come packaged with an experimental command line installer, archinstall, which can assist with installing Arch Linux.
gollark: Arch is largely based on binary packages. Packages target x86-64 microprocessors to assist performance on modern hardware. A ports/ebuild-like system is also provided for automated source compilation, known as the Arch Build System. Arch Linux focuses on simplicity of design, meaning that the main focus involves creating an environment that is straightforward and relatively easy for the user to understand directly, rather than providing polished point-and-click style management tools — the package manager, for example, does not have an official graphical front-end. This is largely achieved by encouraging the use of succinctly commented, clean configuration files that are arranged for quick access and editing. This has earned it a reputation as a distribution for "advanced users" who are willing to use the command line. The Arch Linux website supplies ISO images that can be run from CD or USB. After a user partitions and formats their drive, a simple command line script (pacstrap) is used to install the base system. The installation of additional packages which are not part of the base system (for example, desktop environments), can be done with either pacstrap, or Pacman after booting (or chrooting) into the new installation.
gollark: On March 2021, Arch Linux developers were thinking of porting Arch Linux packages to x86_64-v3. x86-64-v3 roughly correlates to Intel Haswell era of processors.
gollark: The migration to systemd as its init system started in August 2012, and it became the default on new installations in October 2012. It replaced the SysV-style init system, used since the distribution inception. On 24 February 2020, Aaron Griffin announced that due to his limited involvement with the project, he would, after a voting period, transfer control of the project to Levente Polyak. This change also led to a new 2-year term period being added to the Project Leader position. The end of i686 support was announced in January 2017, with the February 2017 ISO being the last one including i686 and making the architecture unsupported in November 2017. Since then, the community derivative Arch Linux 32 can be used for i686 hardware.
gollark: Vinet led Arch Linux until 1 October 2007, when he stepped down due to lack of time, transferring control of the project to Aaron Griffin.
