What is the symbiotic relationships between a lamprey and salmon?
Sharks and lampreys are both types of fish that have cartilaginous skeletons rather than bony skeletons, which is a category officially known as the elasmobranchs. Bony fish in comparison are called teleosts.
Do fishes have bones?
Answer yes,fish do have bonesyes, bony fish (i.e., Teleosts) have bones, but some do not: e.g., invertebrates like cuttlefish, jellyfish or mulloscs, and cartilaginous fish (i.e., Elasmobranchs) like sharks, skates or rays. Answer: fish do have bones.No. They have flexible cartilage like we have in our noses. We call them bones anyway even though there not. The bone meal you buy for the garden is ground up fish cartilage. If it were bone, it would be useless for a soil conditioner. It is a good source of calcium though. For a comparison of bone across species, one may refer to the following:http://www.ejbjs.org/cgi/reprint/51/3/456.pdf
A fish that has no bones?
Sharks belong to the Chondrichthyes class which means that they lack what is called "true bone". Their "skeleton" is made up of cartilage, which is the same as the human ear, so they do not have an actual skeleton.
Where do fish like to go on vacation?
Because fish are exothermic (meaning they use heat from outside of their body) they will often become more sluggish or lethargic during winter. Other than that, they will try to keep their same habits. And even pond fish will need a more deeper pond to hibernate.
Which fishes has a skeleton made of hard bone?
The taxonomic classification of fish that have hard, bony skeletons is teleosts.
What fish group has the greatest number of species?
The fish group with the greatest number of species is the teleosts, which belong to the class Actinopterygii. Teleosts account for over 26,000 species, making them the most diverse group of vertebrates. This group includes familiar species such as salmon, tuna, and goldfish, and they are characterized by their bony skeletons and advanced anatomical features.
Is cuttlefish a true fish?
The term "true fish" would normally be applied to bony fish, technically known as teleosts. The cuttlefish is not a teleost, it is a cephalopod, which is a type of mollusc.

They eat · Octopuses · Teleosts fishes · Crabs · Goat fish · Squirrel fish · Eels · Parrot fish · Tiger fish · Damselfish · Surgeon fish
What is the difference bwtween teleosts and elasemobrache?
Teleosts are a diverse group of bony fish that belong to the class Actinopterygii, characterized by their advanced skeletal structures and swim bladders, which aid in buoyancy. Elasmobranchs, on the other hand, are a subclass of cartilaginous fish, including sharks and rays, characterized by their skeletons made of cartilage rather than bone. This fundamental difference in skeletal structure, along with variations in reproductive strategies and ecological roles, distinguishes the two groups within the aquatic ecosystem.
What members of the class Osteichyes are the most abundant and diverse vertebratesWhat members of the class Osteichyes are the most abundant and diverse vertebrates?
The most abundant and diverse members of the class Osteichthyes, commonly known as bony fish, are the teleosts. Teleosts make up the majority of fish species, with over 30,000 identified, including familiar groups such as salmon, tuna, and goldfish. Their evolutionary adaptations, such as specialized feeding mechanisms and varied reproductive strategies, contribute to their vast diversity and ecological success in aquatic environments.

What is a telelosts?
Teleosts are a diverse group of bony fish that belong to the infraphylum Osteichthyes and are characterized by a range of advanced features, including a mobile jaw and a swim bladder that aids in buoyancy. They represent the largest and most varied group of fish, encompassing over 26,000 species, including familiar types like salmon, tuna, and goldfish. Teleosts are notable for their evolutionary adaptations, which allow them to thrive in various aquatic environments. Their evolutionary success is partly due to their efficient reproductive strategies and varied feeding mechanisms.
Why are cartilaginous fish called cartilaginous fish?
Cartilaginous fish, also known as elasmobranchi, have skeletons made of cartilage rather than bone. Bony fish, also known as teleosts, have skeletons made of bone.

What is Horizontal septum?
The horizontal septum is a structure found in certain fish species, particularly teleosts, that separates the body cavity into dorsal and ventral compartments. This partition helps in organizing the internal organs and can play a role in locomotion by providing support for muscle attachment. It is particularly significant in the context of the fish's swimming mechanics, influencing how the body moves through water.
