Results for “neuromast”

neuromast

Individual sense organ of the lateral line system, comprising nerve fibres connected to a cluster of sensory cells.

neuromastic pitting

Severe physical condition of unconfirmed origin occurring in certain fishes which appears related to poor water quality and/or nutrition. The primary symptom is necrosis of the tissue surrounding neuromasts on both the head and body and if left unchecked the disorder can result in death. Similar to, but not analagous with, head and lateral line erosion, and does not appear to occur in nature.

head and lateral line erosion

Severe physical condition relatively common to certain fishes in captivity and also known as hole-in-the-head. Sometimes attributed to protozoan parasites of the genus Hexamita or an autoimmune disorder though these theories remains unconfirmed. Certainly associated with and exacerbated by poor water quality and/or nutrition, however. Initially manifests itself as small lesions, normally on the head of an affected individual, but may also extend along the lateral line and into the unpaired fins. If left unchecked these lesions can develop into larger, whitish pits and the condition may prove fatal. Often abbreviated to HLLE and similar to, but not analagous with, neuromastic pitting. Does not appear to occur in nature.

lateral line

Sensory organ comprising a series of neuromasts running along the head and flanks and used to detect movement and vibration in the surrounding water. Also known as the lateralis system and visible as one or more rows of pored scales of varying length in many fishes.
