Results for “dermal”

dermal

Of or relating to skin.

Used in 3 profiles

dermal bone

Bone-type ossifying directly from connective tissue membranes and thus lacking a cartilaginous predecessor. Tend to be more numerous in primitive fish forms.

Used in 5 profiles

odontode

Rigid, dermal structure resembling a tooth or bristle found in certain fish taxa, notably many neotropical catfishes. Also known as a dermal tooth and has a structure comparable to that of an oral tooth, with dentine surrounding a central pulp cavity covered by a superficial layer of enamel or similar material. Often more pronounced or extensively-distributed in males than females.

anguloarticular

A compound bone formed by the fusion of the dermal angular and the cartilaginous articular and comprising the posterior part of the lower jaw.

antorbital

A small, paired dermal bone lying lateral to the nasal bone in front of the eye.

Used in 2 profiles

branchiostegal ray

One of the dermal, bony (sometimes cartilaginous), bilaterally paired, flattened struts inserting on the epihyal and/or ceratohyal (sometimes the interhyal and hypohyal) that supports the branchiostegal membranes.

Used in 4 profiles

circumorbitals

Series of dermal bones surrounding the eye, including the suborbitals and supraorbitals.

clavicle

Refers to the collar bone in human anatomy. Present in the pectoral girdle of some fishes as a paired, dermal bone ventral to or fused with the cleithrum.

contact organ

Dermal, bony growth or spicule normally protruding from one or more fin rays or scale margins. Present on parts of the body or fins that come into contact with the female during spawning in males of some fishes.

verrucose

Being covered with small, dermal, wart-like projections.

Used in 1 profile

breeding tubercle

Raised, epidermal structures developing on the head, body or fin rays during the spawning season in some fishes. Usually occur only in males, and sometimes referred to as 'nuptial tubercules'.

saprolegnia

Genus of aquatic fungi, some species of which attack fishes. Normally a secondary pathogen attacking previously damaged tissue and causing cellular necrosis alongside other epidermal damage. Generally visible as a whitish or greyish filamentous fungus and thus commonly referred to as cotton-wool disease.

tubercle

A small, rounded, epidermal projection or protuberance present on the head, body, or fins of some fishes. Often developing temporarily during the spawning season and/or in males only.
