rockfish are not very threatened by their prey, since they are primarily much smaller fish and crustaceans. if you were referring to their predators, they disguise themselves as rocks, hence the name, and are often poisonous.
they protect themselves with their like rock shells.
they grow hard shells to protect themselves against predators and pincers so the can catch their prey. If they didn't have these things then the species could die out.
Camouflage. Many animals use camouflage to enable them to blend in with their environment. If they are prey, they are hiding from predators. If they are predators, they employ camouflage so that they may sneak up on their prey. Fish are no different. Stonefish, for example, cannot swim quickly, so they camouflage to look like a rock in their surroundings in order to fool potential predators.
Stonefish. The fish looks like a stone and looks rather brown
Sunfish,I assume you mean rock bass ,pumpkinseed,bluegill,ect,more than likely protect themselves,as a first measure,by hiding and getting out of the way of bigger fish fast.Second, it seems to me all sunfish have pretty sharp spines the stick out of their dorsal fins,and there always pointing back,away from the head.This would seem to me that bigger fish that try to chase the sunfish,to swallow it from behind,get stuck in the mouth with those sharp spines.I once caught a nice calico (aka rock bass) on a minnow jig,and I stuck myself pretty good on back fin while taking it off the hook,it drew blood!
YES there are hundreds of sea creatures that are well camouflaged. Like the rock fish it blends in with the rock and is quite piousness and the leafy sea dragon ( sea horse) is well camouflaged into seaweed and other types of sea plant.
In rock climbing, a rock anchor is a system by which a rock climbing will build protection to which he can fix his rope so as to protect him in the event of a fall. Rock anchors are a study in themselves and often involve many different methods, one of the main ones being equalization.
Stonefish are venomous, and the stink can be fatal to humans. It is one of the most venomous fish known, found in the sea and in some rivers. It lies in wait, camouflaged as a rock, to catch its prey.
Rock wallabies do not spend all their time out on rock ledges. They are so called because they frequent rocky slopes and hillsides, and are built for this terrain, rather than flat terrain. Rock wallabies feed and shelter in bushland and scrub.
Rock fish, that like to play pool
yes, they are
A rock fish is roughly the same size as my freakishly giant penis
