Specialists believe the eyespot is intended to trick predators into thinking that the fishs tail is actually its head so the predator is likely to attack the least vulnerable end of the butterflyfishs body, and the predator is likely to be fooled by the direction the butterflyfish swims when it attempts to evade the predator. Many schooling fishes are able to quickly react to the escape reaction of other fish, at least in part because of their lateral line system. gamma rays. Cite this Article. The same is true for a variety of catfishes, many of which also possess sharp spines. These fishes are masters of the art of cryptic color as they routinely alter the hue and pattern of their skin to closely match that of their surroundings. However, a possibility exists that sailfish with strong side preferences could become predictable to their prey because fish could learn after repeated interactions in which direction the predator will hit. In essence, each member of the school operates under the premise that it is safer hiding among the school than it is to roam the waters alone. By swallowing a lot of water when alarmed, balloonfishes and pufferfishes can inflate their bodies, erecting a number of very sharp spines.

The sailfish is named for its sail-like dorsal fin and is widely considered the fastest fish in the ocean, clocking in at speeds of 70 mph. 3.

Electric rays cannot use their electricity-producing ability frivolously. It takes time for them to store more electricity and in the interim might have trouble warding off another attack. However, sailfish caught and released by sport fishermen have an average lifespan of only 4 to 5 years. When they feel threatened, they will "play dead.". Many ichthyologists say that the concept of safety in numbers plays a fundamental role in schooling behavior. (2013). [citation needed].

Did you find this page helpful? But they are far from defenseless. In younger animals the spines are especially sharp, and when erected make an unpleasant surprise for an attacker such as a large sea bass or angelshark. 6) Distraction Displays. Explanation: The bats are nocturnal. As a result, injured fish increase in number over time in a fish school under attack. As a last resort when grabbed by a predator, seals will bite and thrash to defend themselves.

It also raises the large fin on its back to make itself appear much larger than it actually is. A variety of eels such as snake eels and cusk eels are also adept at quickly burying themselves in sand to escape harm. 8. In addition, thin-bodied species such as angelfishes and butterflyfishes can quickly slide into hiding places when danger threatens. 1 The hairy frog breaks its own bones when threatened and uses them as spines to protect itself. 4) Nest Cover and Concealment. Another notable characteristic is the elongated rostrum (bill) consistent with that of other marlins and the swordfish, which together constitute what are known as billfish in sport fishing circles.
