Section "Zoology Spotlight" will take care to disclose any information about species or groups of animals bizarre but very little known to the general public, only that I will choose based on what is cool. The first group is to examine the Pycnogonida, or spiders, sea creatures have found that I always look absolutely extraordinary. As you can see from the photos, the general appearance is the result of an erotic encounter between a lover opilione (spider-like creatures with the body to the ball and thread-like legs that are so disgusting) and a facehugger Alien. Viewed their appearance is not exactly sexy, many racist Arachnophobia not be surprised to discover that the adorable picnogonidi are part of the Chelicerata, the group of animals that includes spiders and Xifosuri. The last name does not tell you anything? "Horseshoe crab" is better? No? As I imagined. Bow your head and be ashamed. Returning to the Pycnogonida, it is easy to see that their skeletal legs are long as much as their little body is small and slender, which leaves little room for the organs. The entire body of these marine arthropods is devoted to saving space: every muscle is made from a single cell, the respiratory system is missing (due to the thinness of the animals just the simple diffusion of gases), the egg sacs are hung outside two-legged specialized digestive system and the equipment extends even within some of the limbs. What do these dudes all day? Roam the grounds using their proboscis to prey mushy and sedentary marine organisms such as anemones and bryozoans. Ranging from 1 mm in diameter and 90 cm, and live in all seas, from the depths of the Arctic to the Mediterranean - be warned!
