coral

Any marine animal of the class Anthozoa, these being characterised by possessing a horny or calcareous skeleton, aggregations of which form coral reefs and islands.

Used in 13 profiles

coral reef

Erosion-resistant aquatic structure formed from living corals, their rock-like skeletal secretions and calcium carbonate deposits from other organisms such as calcareous algae, molluscs, and protozoans.

coral sand

Sand originating from marine environments via bioerosion of the calcareous skeletal structures possessed by some organisms. Coral is not the chief constituent, however, with the majority of material deriving from foraminifera, calcareous algae, molluscs, and crustaceans.

Used in 6 profiles

coralline algae

Any red algae of the order Corallinales, characterised by possession of a hard thallus containing calcareous deposits. Often pink, purple or red in colour.

littoral

Of, relating to, or located on the shore of a sea or lake.

pectoral

Of, relating to or located on the chest, breast, or thorax; used to refer to a single pectoral fin in relation to fishes.

pectoral girdle

Bony or cartilaginous structure supporting the forelimbs or anterior fins in vertebrates.

pectoral-fin

Anterior, paired fin attached to the pectoral girdle of fishes, usually just behind the opercle and corresponding to the forelimbs of higher vertebrates. Assists in controlling direction of movement and swimming speed. Frequently abbreviated to 'P' or 'P1' in scientific papers.

postoral pouch

A transverse, hollow, pouch-like structure opening anteriorly and located on the ventral surface, immediately posterior to the mouth, in some members of certain balitorid genera, e.g., Gastromyzon, Neogastromyzon.

temporal

Of, relating to, or limited by time or the material world.

Used in 10 profiles

apical

Refers to the tip or cusp of an oral tooth, or denotes orientation towards the apex or tip of a fin, fin-spine, etc..

bubble nest

Aggregation of air-filled bubbles blown via use of an oral secretion constructed by males in some fish species. Such nests usually float and sometimes contain pieces of plant material for improved solidity. Fertilised eggs are deposited and incubated inside the nest and typically guarded by the male.

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.

allelopathy

A biological phenomenon by which an organism produces one or more biochemicals that affect the growth, survival, and reproduction of others. Typical in certain plants, algae, bacteria, coral, and fungi.

aragonite

Naturally-occurring, crsytalline form of calcium carbonate with a notable buffering capacity. Popular as a substrate or substrate additive in marine and freshwater aquaria where pH and hardness must be maintained at high levels, and has a more rapid, effective effect than coral sand, for example.

axil

The upper angle between a fin and the body of a fish, most often used in reference to the pectoral fin.

axillary process

A modified, often elongate, scale or group of scales located at the base of the pectoral or ventral fins in some fishes.

baudelot's ligament

Ligament, sometimes ossified, which joins the 1st centrum with the supracleithrum. Helps anchor the pectoral girdles to the sides of the fish.
