Everything you need to know about Osteichthyes "Bony Fish" in under 5 minutes

Summary

This intriguing video explores the world of Osteichthyes, or bony fish, which make up 96% of all fish on Earth. They are cold-blooded vertebrates that breathe through gills and utilize fins for movement. Bony fish are the most diverse group of vertebrates, with over 28,000 species thriving in various aquatic environments. From food to medicine, they offer great benefits, such as omega-3 for heart health. Adaptable to a wide range of habitats, including rocky shores and deep seas, certain species like mud skippers and African lungfish have unique survival adaptations. Their reproduction varies greatly with some species being hermaphrodites. Bony fish diets can include crustaceans, insects, and even their own species. They communicate via sound based on mood and behaviors, adding another layer to their fascinating existence.

Overview

Bony fish, scientifically known as Osteichthyes, are a remarkable class of cold-blooded vertebrate that dominate our oceans and freshwater bodies. Comprising 96% of all fish species, these creatures come in all shapes and sizes, occupying a vast array of aquatic habitats from tropical to polar waters. They are characterized by their bony skeletons, paired fins, and gills, making them perfectly suited for life in water.

With over 28,000 species, bony fish showcase incredible diversity and adaptability. Certain species have evolved unique features for survival, such as the mud skippers' ability to spend time on land or the African lungfish's reliance on air breathing. Bony fish play a crucial role in human nutrition and medicine, providing essential nutrients like omega-3 fatty acids that promote heart health.

Reproduction in bony fish is equally fascinating, with mechanisms varying greatly among species. Some bony fish exhibit hermaphroditism, allowing them to change sex or simultaneously possess both male and female reproductive organs. Moreover, their diet is as varied as their habitats, ranging from carnivorous to herbivorous to omnivorous feeding habits. These fish even communicate through sound, revealing their complex social and behavioral interactions.

Chapters

• 00:00 - 00:30: Introduction to Osteichthyes The chapter titled "Introduction to Osteichthyes" provides an overview of bony fish, which are scientifically known as Osteichthyes. These fish are part of the chordata phylum and represent 96% of all living fish species. They are described as cold-blooded vertebrates with the ability to breathe through gills and move using fins. Key characteristics of bony fish include having a skeleton made of bones, scales, paired fins, one pair of gill openings, jaws, and paired nostrils. Additionally, most bony fish possess swim bladders. The chapter highlights that there are over 28,000 known species of bony fish.
• 00:30 - 01:30: Species Diversity and Habitat Adaptation The chapter entitled 'Species Diversity and Habitat Adaptation' discusses the remarkable diversity of bony fish, which represents the most species-rich class of vertebrates. The text emphasizes the utility of bony fish for both food and medicinal purposes, such as cooked salmon and the omega-3 fatty acids that contribute to heart health. Additionally, the chapter highlights the wide range of habitats these fish inhabit, from tropical to polar waters, and even different types of freshwater environments, demonstrating their adaptability to various ecological niches. Bony fish can be found at depths from 11 kilometers below sea level to altitudes of five kilometers above sea level, showcasing their extensive distribution across the world's aquatic environments.
• 01:30 - 03:00: Reproductive Strategies Different species have adapted to thrive in various habitats, including rocky shores, coral reefs, kelp forests, rivers and streams, lakes and ponds, under sea ice, the deep sea, and in fresh, salt, or brackish water.
• 03:00 - 05:00: Feeding Habits and Behavior African lungfish exhibit adaptations that allow them to remain submerged for extended periods by retaining air in their lungs, essential for respiration. These fish necessitate periodic access to the water's surface to avoid drowning. The chapter also introduces various fish species by their common and scientific names: the salmon (samosa), Atlantic bluefin tuna (thanos thinness), ocean sunfish (mola mola), and rainbow trout (uncaragnus).

• 00:00 - 00:30 our class is scientifically known as osteothis or more commonly known as bony fish they are part of the chordataphylum bony fish make up 96 of all living fish in our biosphere they are cold-blooded vertebrates who breathe through gills and use fins for movement they have general characteristics like skeleton of bones scales paired fins one pair of gill openings jaws and paired nostrils most bony fish have swim bladders as well over 28 000
• 00:30 - 01:00 different bony fish species have been discovered which is the most amount of species discovered in all vertebrae classes these fish can be used for food and medicine such as cooked salmon or the omega-3 they contain which helps prevent heart attacks and improves good cholesterol overall bony fish live in almost every body of water type they live in tropical water temperate water polar seas and almost every fresh water body they usually live from 11 kilometers below sea level to about five kilometers above sea level
• 01:00 - 01:30 different species are adapted for different habitats such as rocky shores coral reefs kelp forests rivers and streams lakes and ponds under sea ice the deep sea fresh salt and brackish water some species that you may not be aware of are mud skippers they have adapted to commonly spend time on land in short amount of time they do this by carrying small amounts of water in their gill cavities and when this supply begins to evaporate they return to the mud holes to replenish their water
• 01:30 - 02:00 african lungfish families adapt to be underwater for a longer amount of time by keeping air in their lung for respiration these fish must have access to the water's surface or they will drown as you can see here this is salmon scientifically known as samosa this is an atlantic bluefin tuna scientifically known as thanos thinness this is an ocean sunfish scientifically known as mola mola this is rainbow trout scientifically known as uncaragnus
• 02:00 - 02:30 mycus most bony fish become sexually mature one to five years after birth they can reproduce sexually and or asexually it depends on the species some bony fish are hermaphrodites which means they produce both egg and sperm cells sequential hermaphrodites are born with one gender and can change sex sometime during their life synchronous hermaphrodites have both sperm and egg producing organs at the same time self fertilization is possible in a
• 02:30 - 03:00 few species a few species are unisexual there is no fusion between the sperm and the eggs so unisexual species are always and all female they then can mate with closely related male species changes in temperature sunlight currents tides moon stages and presence of spawning areas can affect or stimulate reproduction some bony fish may spawn many times a year many bony fish reproduce once a year until they die and other bony fish may reproduce only once during their
• 03:00 - 03:30 lifetime external fertilization of the eggs will be made when male and females are like really sperm and eggs into the water which releases hundreds of thousands of eggs however many of them are eaten by other osteoactive species and by doing this the number of bony fish stays consistent and at a safe amount some species also have internal fertilization osteoactive diet consists of crustaceans which are cousins of shrimp insects
• 03:30 - 04:00 larvae any dead fish remains fish eggs including their own species and it is to be mentioned that they are not one specific plane since osteothesis can be omnivorous carnivores herbivorous or even detrivores this is the ancestral cladogram for chordata osterectis this process represents the physical evolution of each species from vertebrae
• 04:00 - 04:30 with lampreys to jaws with sharks to bony ribs with ray finned fish to choney with lungfish all the way up to fingers and toes with amphibians their behavioral tendencies are the following many bony fish will produce a sound depending on their feeling and mood if they are territorial aggressive social or even for reproductive wants these fish will make a sound that other bony fish will hear and they will come to the sound or even back
