Order Torpediniformes
Order Torpediniformes:
They are also known as electric rays and are flattened cartilaginous fish. They have enlarged pectoral fins, and can produce electric discharge. Their electric volts can range from 8-220 volts.
Kingdom: Animalia
Phylum: Chordata
Class: Chondrichthyes
Subclass: Elasmobranchii
Superorder: Batoidea
The most popular members of this order are the Genus Torpedo and there are 69 species in 4 families. They will become stiffened of paralyzed if someone steps on them. Their bodies are thick and flabby, and they live in shallow, coastal waters. They can also be found in deep waters, and they are sluggish and slow moving. Electric rays feed on invertebrates or small fish. Their venomous tails were once used to numb the pain of childbirth in ancient Greece. Electric rays have poor vision and are grouped into 12 genera and 2 families.

Order Myliobatiformes
Kingdom: Animalia
Phylum: Chordata
Class: Chondrichthyes
Subclass: Elasmobranchii
Superorder: Batoidea
They are one of the four orders of Batoids and are cartilaginous fishes related to sharks. At one point, they were included in the order Rajiformes, but Phylogenetic studies proved this wrong and they now have their own order. They are independent from skates, and they have very flat bodies, which is a characteristic for all rays. Most of them have 5 pairs of gill slits, and they live in temperate or tropical waters. There are 33 genera in 10 families and most have sawed-edge spines or stingers. These spines or stingers are one characteristic that identifies this order and makes them different from the other orders.

Order Rajiformes:
Kingdom: Animalia
Phylum: Chordata
Class: Chondrichthyes
Subclass: Elasmobranchii
The super order of Rajiformes are Batoidea, and they are one of the four orders of this super order. They are also cartilaginous fishes related to sharks. They have greatly enlarged pectoral fins, and their eyes are located on the surface of their head. They are found all over the world, and there are thirteen families of Rajoids. This picture shows the eyes on the surface of their head, and you can see that they have flat bodies, like all rays.

Order Pristiformes
Pristiformes:
Pristiformes are sawfish, and they obtained that name from their long saw-like tails. Their tips have sawed edges which can be used as a defence mechanism. Sawfish are quite long and can grow to be u to 7 metres long. Pristidae are the only family within this order, and this order is almost extinct. They have a rostrum, which helps them dig at sea level to find food such as crustaceans. |
