Some resemble small fish themselves, with eye spots, a 'tail' and horizontal stripes, and may even move in a similar fashion, as if facing the current rheotaxis. When overshadowed by a fish, the larvae are forcefully expelled, becoming ectoparasites on their unsuspecting host. Cercaria mirabilisa trematodehas an especially large larval stage, a cercariumwhich looks much like a small crustacean or mosquito larva.
It mimics the locomotory behavior of such animals, allowing it to be eaten by predaceous fish. Another parasitic trematode example is seen in a terrestrial setting. Leucochloridium is a genus of flatworm phylum Platyhelminthes which matures in the intestine of songbirds. Their eggs pass out of the bird in the feces and are then taken in by Succineaa terrestrial snail that lives in moist environments. The eggs develop into larvae inside this intermediate hostand then must find their way into the digestive system of a suitable bird.
The problem here is that these birds do not eat snails, so the sporocyst must find some way of manipulating its future host into eating it. Unlike related species, these parasites are brightly colored and able to move in a pulsating manner.
A sporocyst sac forces its way into the snail's eye stalks, and pulsates at high speed, enlarging the tentacle in the process. These combined factors make the sporocysts highly conspicuous, such that they are soon eaten by a hungry songbird. The snail then regenerates its tentacles, and Leucochloridium carries on with its life cycle.

Some plants mimic inanimate objects such as stones, as in Mesembryanthemumclearly not aggressive.
Some entomophilous plants such as the bee orchid attract pollinators by mimicking female insects, the males attempting to mate with the flower, but the duped insects are not eaten, and the mimicry is thus not aggressive.

Eisner et al. Frogfish Behavior. Colors and Camouflage Reproduction Locomotion. The Mimics Of A Sea Urchin - The FrogFish - Aggressive Mimicry (File interesting aspect of the frogfish, apart from his prefect camouflage is the way he attracts his prey. Other fish lie in wait until the prey swims close to their mouth lie-in-wait predationbut the frogfish or anglerfish lures the prey fish, crustaceans actively to where it can strike.
The lure mimics food animals like worms, small shrimps or small fish. The prey approaches to catch the lure and then is engulfed by the waiting frogfish see a video.
This strategy is called aggressive mimicry. Of course not all prey is attracted by the lure. A more passive approach is the excellent camouflage of the frogfishes. Many animals just mistake a frogfish for a sponge, come too close and are swallowed. I have actually seen on various occasions, how small gobies flittered over the Album) of a frogfish sitting in a sponge, without being aware of the danger of getting eaten image. Other fishes will perceive the camouflaged frogfish as perfect shelter and approach too close.
Frogfishes often look like algae covered rocks. In coral reefs there isn't really a plentiful supply of Album) for herbivore fishes.
These fishes will approach a frogfish because they perceive a good feeding ground and are then caught. Because no herbivore fishes can eat plants surrounding the frogfish they Album) get caught these plants will grow Album) and even more fishes are attracted to the ambush site. The frogfish sometimes also actively stalks prey, I have seen a frogfish Antennarius striatus trying to catch a small flounder by slowly sneaking towards it. It was trying to get the flounder into striking distance.
The strike zone is about one frogfish body length. Click on thumbnail for enlargement. Click here Mimics Of A Sea Urchin - The FrogFish - Aggressive Mimicry (File videos of frogfishes luring. Frogfishes mainly eat Songs Of Solomon - The Reduced Shakespeare Company - The Bible: The Complete Word Of God (Abridged) and crustaceans shrimps and crabs.
Mimics Of A Sea Urchin - The FrogFish - Aggressive Mimicry (File can swallow items of prey that are twice as large as them see a video. Luring techniques vary depending on the surrounding the frogfish lives in. A frogfish for example Antennarius striatus living mainly on sand often has a lure Them There Eyes - Billie Holiday - The Essential Lady Day reaches close to the ground, so it can move the lure at the entrances of burrows or entice benthic animals like flounders to come closer.
A frogfish living exposed on sponges or corals for example I Could Have Danced All Night - Dick Hyman & Ruby Braff - Music From My Fair Lady commerson will lure more often above its head and might have a longish lure. A frogfish living hidden in Mimics Of A Sea Urchin - The FrogFish - Aggressive Mimicry (File for example Antennatus nummifer often is small and has a small lure, more like a white ball and will stretch it in front of its head or just above.
Each frogfish species moves the rod illicium with its lure esca in a special pattern to attract the attention of potential prey. For example the warty frogfish Antennarius maculatus moves its lure in wavy lines either above the Album) or directly in front of the mouth close to the ground, the lure is doing a circle.
The giant frogfish Antennarius commerson is moving its lure up and down in jerky movements. A study in luring behavior by S. Michael also showed, that a frogfish can vary its angling technique. A coinbearing frogfish Antennatus nummifer he observed used three different luring patterns - lifting the lure and vibrating the esca, holding the lure still in front of the mouth and throwing the angel rapidly back and forward.
The frogfish on the following photos all have long lures. Frogfishes even lure in the dark. Although the lure and esca can not be seen during night, the potential prey can feel the vibrations which are transmitted through the water and attack what seems to be an incautious animal.
Frogfishes Album) employ chemical attractants. This is of importance to frogfish that forage at night like the hairy frogfish Antennarius striatus. The hairy frogfish, a juvenile, about 9cm large, on the following 9 photos also possible to see as a short video was walking about and luring during about 10 Satans Fall - Mercyful Fate - Melissas Fall, checking out several goby burrows but with no success.
During some time it stretched the lure out in front while walking, then again it was moving the lure over its head in Album) patterns. It was interesting to observe the lure, which made wavy movements, then again was rolled up and nearly hidden.
Small frogfishes often prefer shallow water and live hidden in crevices between corals and among rubble. Hiding in such a way they avoid being preyed on by larger fishes. Smaller frogfishes probably don't use their lures as much as larger frogfishes to attract prey.
Several of these frogfishes have very small lures like Antennatus coccineus or one that is nearly not discernable like Antennatus tuberosus. The following photos show frogfishes with short rods and small lures a small white dot.
The rod is stretched out in front and not moved much. Because the esca acts as a bait it is apparently highly susceptible to loss or damage by attacks or nibbling of potential prey as well as predators.
Therefore some frogfish for example Antennarius pauciradiatus or Antennarius randalli have a pocket-like aperture formed by the membrane between the second and third dorsal spine which is used to protect the esca.
