Fish may bite other fish as a form of competition for territory or resources, establishing hierarchy within the group, or in defense against perceived threats. These behaviors can vary depending on the species of fish and their social structure.
The Northern Puffer fish has a skeleton made up primarily of cartilage, rather than bones. This cartilaginous structure provides flexibility and buoyancy for the fish as it navigates its aquatic environment. The lack of true bones in the Northern Puffer fish allows it to inflate its body with water or air as a defense mechanism against predators.
puffer fish are light brown but white when puffed up.
Firstly remember that FISH HAVE SCALES!!!I don't think it would be a fish if it had fur or skin. Blow fish have scales, but also have many spikes across their body. These spikes are a form of defence, other fish are not so keen to eat something that would scratch on their throat and mouths!!! Hope this helps.
to eat or swim away from the predator
A frog can use its coloration to blend with its surroundings, sometimes fish can blend Into their surroundings this is a defense tactic
Predators of puffer fish include sharks, dolphins, and larger fish species. These predators are attracted to the puffer fish's flesh and may also target them for their toxic defense mechanism.
the skate's defense is the thorns on its back (throns are located on its back and tail)
Well let me give you the reason, they are known for eating everything from people to fish! Also, their defense can be just biting another fish. They really don't have a predator so most of the time its chomp! But if humans try to catch them...you are in trouble so watch out!
The main and only mean of protection for clown fish is the anemone. This is the reason why clown fish spend all their lives swimming nearby anemone. They protect each other. It is called "symbiosis".
A defense adaptation is a certain ability that an animal can use to protect itself form predators. Ex: Pocupines have pointy quills to protect it from being eaten. Ex: Puffer fish can blow themselves up to make themselves look bigger and scare away other fish that want to make them dinner.
Sea anemone are not poisons to humans in fact they are not poisonus us to some fish such as the clown fish. Sea anemones use their poisons has their defense "weapon". Sea anemones are helpful to clown fish because that's wear they live and clown fish predators are threaten by their poisons.So to answer your question no they are not. :)
When the puffer fish inflates its body to increase its size it is a behavior called a defense mechanism. Puffer fish have highly elastic stomachs and the ability to quickly take in air or water to puff themselves up. This turns them into an inedible ball.
What's generally known as a "stone fish" (though many other fish are often given this name) a bony, saltwater, bottom-dwelling fish with cryptic camouflage that's normally found in Australia and Indonesia. It has spines on its back that, if stepped on, inject the victim with deadly venom as a defense mechanism.
Predators that pose a threat to puffer fish in their natural habitat include sharks, dolphins, sea turtles, and some species of larger fish. These predators are attracted to the puffer fish due to their slow swimming speed and defense mechanism of inflating themselves with water or air when threatened.
On the Natural Resource Defense Council (NRDC) site, hake are placed in the list of fish with the lowest mercury levels. Their mercury levels are similar to that of other common fish such as anchovies, pollock, and salmon.
