What type of fish are sharks and skates?
Sharks are cartilaginous fish, belonging to the subclass Elasmobranchii. Skates are also cartilaginous fish, but they belong specifically to the family Rajidae within the order Rajiformes.
What is the difference between primitive fish and the most advanced types?
Primitive fish are typically simpler in structure and behavior, with characteristics like cartilaginous skeletons and lack of jaws. In contrast, more advanced fish have evolved adaptations like bony skeletons, jaws, and specialized sensory organs for improved survival and reproduction. They also exhibit more complex behaviors and reproductive strategies compared to primitive fish.
The most primitive vertebrates are members of the group of a jawless fishes b amphibians c artilaginous fish d birds e bony fish?
A: jawless fish
Is a hagfish a cartilaginous fish?
Hagfish are cartilaginous, meaning their skeletons are made from cartilage. FALSE what the person just wrote is wrong. Hagfish are neither cartilaginous or bony fish. Although they have cartilage in their bodies, they belong to a third category called Jawless fish. Jawless, cartilaginous, and bony are the 3 types of fish.
To which group do sharks belong?
There are many families of fish, but all belong to the phylum Chordata. That is about as specific as you can get in terms of encompassing ALL fish. However, MOST fish, called are classed in Osteichthyes(Bony Fish), Sarcopterygii (lobe finned fish) and Chondrichthyes(sharks, rays, skates, etc), and a hundred or so species of primitive jawless fishes.
Do cartilaginous fish have operculum?
Jawless fish are cartilaginous, but they do not have jaws. Class Chondrichthyes, which contains most cartilaginous fish, like sharks, have powerful jaws.
What group do jawless fish belong to?
Jawless fish belong to the group known as Agnatha. This group includes species such as lampreys and hagfish, which are characterized by the absence of jaws and paired fins. Agnatha is considered one of the most primitive classes of vertebrates, and these fish have a unique, elongated body structure and a cartilaginous skeleton.

What are the 3 types of fish?
Cartilaginous Fish, their body frame in mainly cartilage. Tough and flexible, cartilage provides enough l support to allow these fish to grow to very big sizes. Cartilaginous fish include sharks, rays, skates and chimaeras. Ray-finned fish are the most diverse of the three groups of fish. The group includes mor than 23,000 species such as salmon, trout, lanternfish, cavefish, cods, anglerfish and many others. These fish consist of bone. Lobe-finned fish are a group of bony fish that have paired fins. Ancient lobe-finned fish are thought to be the ancestors of the first four-legged land vertebrates or tetrapods.

There are seven classes of vertebrates. Three of these are considered fish, and they are the jawless fish, bony fish, and cartilaginous fish. Four live on land, and they are amphibians, reptiles, birds, and mammals.
What fish have a skeleton made of bone?
Fish with a skeleton made of bone are classified as bony fish, or Osteichthyes. This group includes a wide variety of species, such as salmon, trout, and goldfish. Bony fish possess a skeleton primarily composed of calcified bone, contrasting with cartilaginous fish like sharks and rays, which have skeletons made of cartilage. Bony fish are the most diverse group of vertebrates, making up a significant portion of all fish species.
