Tonicella Lokii
''Tonicella lokii'', commonly known as the flame lined chiton or Loki's chiton, is a chiton in the lined chiton genus ''Tonicella''. Size and description Like most chitons in this genus, ''T. lokii'' has blue, white, purple or black zig-zaged lines on each of the eight valves. The background color of the valves is often brown or red, but can also be bright blue or yellow to orange. The girdle is hairless and brown to red or pink. It has radiating bands and often bears a yellow or white broken concentric line, alternating with radiating bands.Clark, R.N. (1999).

Similar species ''Tonicella lineata'' is extremely similar but does not have radiating bands on the girdle.

Chiton
Chitons () are marine molluscs of varying size in the class Polyplacophora (), formerly known as Amphineura. About 940 extant and 430 fossil species are recognized. They are also sometimes known as gumboots or sea cradles or coat-of-mail shells or suck-rocks, or more formally as loricates, polyplacophorans, and occasionally as polyplacophores. Chitons have a shell composed of eight separate shell plates or valves. These plates overlap slightly at the front and back edges, and yet articulate well with one another. Because of this, the shell provides protection at the same time as permitting the chiton to flex upward when needed for locomotion over uneven surfaces, and even allows the animal to curl up into a ball when dislodged from rocks. The shell plates are encircled by a skirt known as a girdle. Habitat Chitons live worldwide, from cold waters through to the tropics. They live on hard surfaces, such as on or under rocks, or in rock crevices. Some species live quite hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Tonicella'' is a genus of chitons known as the lined chitons. MolluscaBase eds. (2022). MolluscaBase. Tonicella Carpenter, 1873. Accessed through: World Register of Marine Species at: https://www.marinespecies.org/aphia.php?p=taxdetails&id=138090 on 2022-06-22 The genus name derives from the Greek ''tonos'' (something stretched, a brace, a strain) and ''cell'' (diminutive).

Tonicella Lineata
''Tonicella lineata'', commonly known as the lined chiton, is a species of chiton from the North Pacific. Size and description ''Tonicella lineata'' is a very colorful chiton, having blue, purple or black straight or zig-zag lines on each of the eight valves. The background color of the valves is often brown or red, but can also be bright blue or yellow to orange. The girdle is hairless and brown to red or pink, often with regular yellow or white patches. This species grows to 5 cm in length. Similar species ''Tonicella lokii'' is extremely similar but has radiating bands on the girdle. ''Tonicella undocaerulea'' is very similar but lacks a dark border to the concentric blue lines on the anterior plate. ''Mopalia spectabilis'' looks superficially similar due to its bright blue wavy lines on the valves, but has a hairy girdle.Baldwin, A. (2007). Illustrated Keys to the chitons (Polyplacophora).

Tonicella Undocaerulea
''Tonicella undocaerulea'', commonly known as the blue lined chiton, is a species of chiton. Size and description The blue-lined chiton features a head plate adorned with zigzagging white concentric lines, which may appear blue while the creature is alive, and lacks a dark border. When in its vibrant state, it often exhibits vivid electric blue stripes and specks. The girdle of this chiton is typically hairless and showcases hues ranging from brown to red or pink, often accompanied by mottling in yellow or white.Baldwin, A. (2007). Illustrated Keys to the chitons (Polyplacophora). Accessed from: Similar species ''Tonicella lineata'' is very similar but has a dark border to the concentric blue lines on the anterior plate. ''Tonicella lokii'' is also similar but has radiating bands on the girdle. ''Mopalia spectabilis'' looks superficially similar due to its bright blue wavy lines on the valves, but has a hairy girdle.

Mopalia Spectabilis
''Mopalia spectabilis'', commonly known as the red-flecked mopalia, is a species of chiton. Size and description ''Mopalia spectabilis'' is a chiton that has a central area of plates 2-7 pitted in longitudinal rows. The girdle commonly banded light orange and brown. This species nearly always exhibits bright turquoise zigzag markings. The girdle bears prominent hairs that are plumed and are said to look like small “bottle brushes”.Baldwin, A. (2007).

Mebibyte
The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures. To disambiguate arbitrarily sized bytes from the common 8-bit definition, network protocol documents such as The Internet Protocol () refer to an 8-bit byte as an octet. Those bits in an octet are usually counted with numbering from 0 to 7 or 7 to 0 depending on the bit endianness. The first bit is number 0, making the eighth bit number 7. The size of the byte has historically been hardware-dependent and no definitive standards existed that mandated the size. Sizes from 1 to 48 bits have been used. The six-bit character code was an often-used implementation in early encoding systems, and computers using six-bit and nine-bit bytes were common in the 1960s. These systems often had memory words ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
