seitiä

Seitiä refers to a category of fish belonging to the family Macrouridae, commonly known as grenadiers or rattails. These deep-sea fish are characterized by their elongated, tapering bodies that end in a narrow tail, resembling a rat's tail, hence their common name. Seitiä are found in oceans worldwide, typically inhabiting abyssal and bathyal zones at depths ranging from a few hundred to several thousand meters. Their diet often consists of small invertebrates and other fish found on the seafloor.

While some species of seititä are commercially fished, particularly in certain regions, they are not as widely consumed as other fish species. Their deep-sea habitat and the specific methods required for their capture contribute to their less prominent role in global fisheries. Research into seititä populations and their ecological roles in deep-sea ecosystems is ongoing. Identification of different seititä species often relies on anatomical features such as fin ray counts and scale patterns. The term "seitiä" itself is Finnish for grenadier.
