Following the discovery of spinoid scales in species of the cardinalfish genus Siphamia, a survey of 20 apogonid genera, using scanning electron microscopy, found that scale ontogeny in the Apogonidae usually proceeds along three phases, cycloid, spinoid and transforming ctenoid, that develop in …

[…] Cycloid and ctenoid scales show considerable variation in their forms, although not always at either the genus or species level, permitting their use for identification purposes. The Salmonidae and, to a lesser extent, the Pleuronectidae, display particularly consistent morphological characters. (Le 11:9, 10, 12; De 14:9, 10) Thus scales (Heb., qas·qas·simʹ, plural of qas·qeʹseth) were one of the easily recognizable signs as to whether a certain fish could be eaten.

Cycloid Scale Armor is an Armor Set from the Sunstalker Expansion.

The growth can be seen in rings on the scale. These rings can be related to the age of the fish. Cycloid scales are thin, circular scales covered by a thin layer of epidermis and mucus.

Cycloid scales have a smooth posterior margin lacking ctenii. The word 'cycloid' comes from the Greek cyclo, meaning circle. Cycloid and ctenoid scales consist of two main regions, a surface 'bony' layer, composed of an organic framework impregnated largely with calcium based salts, and a deeper fibrous layer composed mainly of collagen.

Answer: Fishes possess dermal scales, each scale made of dentine Spines is made of enamel like basal plate of dentine like bony material. These scales are closely set together in skin giving it a sandpaper like quality. CYCLOID (i) Placoid, (ii) Cycloid, (iii) Ctenoid, (iv) Ganoid. 149879.
