Some fish have stinging spines or barbs. When used against smaller sharks, they can be moderately effective. Overall, the fish with the most successful defenses will hide themselves in between rocks or in small crevices. Other fish will start spinning in a large sphere with other fish. There will still be fish picked out of the sphere, but they stand a better chance here than they would darting out on their own. Their protection comes more from behavior than from a body structure.
Defense mechanisms such as camouflage, spines, and poisons help fish escape predators.
Fish do not shiver when cold in the way mammals do. Instead, they have evolved different physiological mechanisms to regulate their body temperature, such as changing their metabolism or seeking warmer water. Some fish may become slower or less active in colder temperatures, but they do not shiver to generate heat.
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.
defence
Some fish that may eat lobsters include groupers, sea bass, and triggerfish. However, lobsters have a hard exoskeleton and are generally not a preferred food source for most fish due to their defensive mechanisms.
discuss defence mechanism
yes
people tend to use defence mechanisms to protect themselves from anxiety
porcupines defense mechanism is that they can shoot out their quills
defence mechanisms
they use the poision to kill each auther
to protect themselves against criticism or other harsh treatment.
The immune system plays an important role in the body's defence mechanisms. It destroys and eliminates the pathogens that invade our bodies.
Denial. Jacks Denial to be rescue someday.
I guess they could if they had the chance and if the lizards defence mechanisms are not too dangerous for the rattlesnake.
Isolation, Undoing, reaction formation are the main three defence mechanisms for OCD. Magical thinking is another mechanism associated with OCD.
They don't really. Their best defence mechanisms are: (1) staying in large groups and (2) swimmimg away fast.
