Flashcards in Final Vocab Deck (35):
1

Redox potential

The oxidation and reduction process, when electrons are lost from one Atom or molecule and gained by another.

2

Reef aquarium

An aquarium that incorporates invertebrates and is similar to a reef in appearance, compared with a fish only set up.

3

Refugium

An area that has remain unaffected by changes in climate over a period of time that have affected neighboring areas, and thus has a more ancient flora and Fauna.

4

Reverse- flow filtration

A biological filtration system in which water flows up into the tank through the base covering instead of having the more usual downward flow.

5

Reverse osmosis

A technique whereby water is forced through a membrane in the reverse way to osmosis, so that the mineral salts are left behind, resulting in pure water.

6

Rotifers

Planktonic organisms, used as first food for the Fry of many marine fish.

7

Salinity

The measure of saltiness of aquarium water. The hobbyist can measure salinity and specific gravity as one and the same.

8

Seagrass

An important retreat for the young of many marine fish, close in sure. Also known as eel grass

9

Sexual reproduction

Reproduction in which the eggs of the female are fertilized by the sperm of the male.

10

Silicone sealant

A slightly flexible adhesive used to bond glass or stop leaks in aquaria, or to create rock and coral formations in the aquarium itself.

11

Siphon

(1) length of tube used to move water from one vessel to another. (2) the inhalant and exhalant organs of a mollusk.

12

Spawning

The part of the reproductive process involving fertilization of eggs.

13

Species only set up

An aquarium that is restricted to displaying just one species

14

Specific gravity

(SG) The ratio of the density of a measured liquid to the density of pure water. Natural seawater has an SG of around 1.025, but Marine aquarium fish are normally kept at 1.020-1.023

15

Spirulina

A type of marine algae highly valued as fish food, available in various formulated diets created especially for herbivorous fish

16

Stripping

The process by which the crust of a Gorgonian (the part housing the polyps) falls away.

17

Substrate

Aquarium base covering

18

Sump

And under tank reservoir that usually holds a trickle filter, mechanical and chemical filters, as well as probes and reactors.

19

Sushi noir

A type of food use for some aquarium fish, which is more commonly sold through human food outlets.

20

Sweeper tentacles

Long tentacles used by aggressive hard corals to sting other nearby corals in order to establish a territory

21

Swim bladder

The hydrostatic Organ enabling fish to maintain their chosen depth and position in water

22

Total system

And aquarium with built in sophisticated filtration and other management systems, providing full water treatment.

23

Trace elements

Elements found in seawater in very small quantities, often much less than one ppm

24

Trickle filter

A biological filter, filled with inert media.

25

Tunicate

See squirts and related organisms belonging to the subphylum to Tunicata

26

Turnover

The water flow rate through a filter. For Marine aquarium a high turnover is recommended.

27

Ultraviolet sterilizer

And ultraviolet light tube, enclosed in a water jacket, through which aquarium water is passed to sterilize it.

28

Undergravel filter

The substrate of an aquarium used as a biological filter

29

Valve

In bivalves, 1/2 of a two valve shell.

30

Vent

In fish, the urogenital opening found between the anus and the anal fin

31

Ventral

Situated at, or related to, the lower bottom side or surface.

32

Ventral fins

Pelvic fins

33

Water change

The replacement of a proportion usually 20 to 25% of aquarium water with fresh sea water mix.

34

Zooanthellae

Symbiotic algae found within the tissue of many curls, and anemones and clams.

35

Zooplankton

Extremely small animals and their larval stages that drift in the water
