Caution KARAPUS!
Karapus Mediterranean (Carapus acus)
Very peculiar and very unusual boyfriends of different types of sea cucumbers are schitovidnoschupaltsevyh karapusov kind of fish. These small fish length of 15-19 cm is used as a lightweight water seeker schitovidnoschupaltsevyh various representatives, including the species of these sea cucumbers.
Carefully surveying sea cucumbers and finding the anus, juveniles are being introduced into it head first. Adults karapusy introduced its tail forward, screwing like a corkscrew into the cloaca, while outside there will be no hanging around one's head ... However, they often have time to turn around its axis at 360 °
Sea cucumbers initially resists entry fish, compresses the body, closes the anal sphincter, but the need for respiratory causes her to reveal the anus, and this uses karapus. If it is forced to pull out of the sea cucumbers, he will once again seek refuge and will not rest until then, until he finds it. It is curious that the sea cucumbers karapus leaving only at night to catch small crustaceans that serve him food, and soon returns to the shelter. Sea cucumbers, obviously, does not have any benefit from such co-existence, on the contrary, it is known that large fish often disrupt water and sea cucumbers are light in her body cavity. The larvae also karapusa getting into the body cavity of sea cucumbers, water feed her lungs and gonads. Only the ability to quickly restore lost parts of sea cucumbers saves from death. Plucked from the body cavity of the host larva tenuis commit violent movement and all his behavior evinces unbearable conditions created for her.
Acquainted with the way of life karapusov, it is easy to understand that their morphological features were formed under the influence of symbiosis with invertebrates. For example, removal of the anal and urogenital openings ahead allows the fish to make their departure without having to leave his master: for this it is enough to stick his head. The shape of the body, and especially its tail part, by the need to be introduced into the inner space of the owners (the same sea cucumbers) through a narrow anus. Undoubtedly, this is linked to the reduction of scales, ventral and pectoral fins, and sometimes, especially painting and so on. D.
