Biology
They have heavy dental plates which they use to crush their hard shelled prey. They feed predominantly on bivalve shellfish.
Distribution Map
Importance
Ecological-They are a popular display aquarium specimen and is often seen in public aquarium facilities.
Economical-They are rarely eaten due to the poor quality of the flesh, but instead are used for fishmeal and oil.

Facts
Large groups of spotted eagle rays may be seen outside of the breeding season. They swim close to the surface and can occasionally be seen jumping clear out of the water. Females give birth to around four live young. They are found in coastal waters in shallow bays and coral reefs. They are wary of divers and are difficult to approach.
Vocabulary
Bycatch- In the fishing industry, the part of the catch made up of non-target species.
Pectoral fins- In fish, the pair of fins that are found one on each side of the body just behind the gills.
Ovoviviparous- The egg develop inside the body and hatch within the mother.
Embryos- An unborn or unhatched offspring in the process of development.
Dorsum- The dorsal of an organism or structure.

Biology
They live in shallow weedy areas especially eel grass beds. In winter they move into deeper waters to escape the rough weather. They are poor swimmer. They rely on their dorsal fin beating at 30-70 time per second to propel it along.

Importance
Ecological- They are important to humans for their aestetic appeal, and their biological value.
Economical- They are use in aquariums and zoos.
Economical- They are use in aquariums and zoos.
Facts
They breath throught gills and have a swim bladder. They have excellent eye sight and their eyes are able to work independently on either side of their heads. This mean they can look forwards and backwards at the same time. The male is the only creature where the male has a true reversed pregnancy. The female transfers her eggs to the male which he self fertilizes in his pouch. Baby seahorses are known as fry and when they are born they are totally on their own.
Vocabulary
Aesthetic- Concerned with beauty or the appreciation of beauty.
Swim bladder-A gas filled sac present in the body of many bony fishes used to maintain and control buoyancy.
Bony fish- Are a taxonomic group of fish that have bone, as opposed to cartilaginous, skeletons.
Taxonomy- Is the science of defining groups of biological organisms on the basis of shared characteristics and giving names to those group.
Ovipositor- Is an organ used by some animals for the laying eggs.
