- Wreathed Weaving Spider
The Wreathed Weaving Spider ( Theridium redimitum), which occurs quite commonly, especially in gardens, becomes at most 5 mM. long; this fat little spider inhabits all kinds of low-growing herbs and shrubs; here it spins (fig. 1) a few leaves together by irregularly oriented threads, on which the small animals that make up its food stick to. The mother attaches the spherical, bluish egg sac to a leaf (fig. 2), keeps watch next to it until the young have hatched, and continues to do so for the few days of their cohabitation. These beautiful spiders are very variable in color and drawing. Transparent and almost white in their early youth, spotted black only on the back of the abdomen; towards the end of June, in July and in August, they have taken on a pale yellow color, some plain, others with a stain on the abdomen, which can be pure pinkish red or partially greenish, circular or oval. In addition, the rim and a line across the center of the head-breast, 6 pairs of round dots on the abdomen, the tip of the probes and the shins are black. grab.

The Water Fleas ( Cladocera ) are the second suborder next to the Leaf-legged. Early in the morning, but also on warm, quiet evenings, and moreover in cloudy skies, these little creatures, the largest of which are seldom longer than 6 mM, swim close to the surface of the water; but they go down to the depths as soon as the sun begins to shine on the water with some force. Some species, by the way, always prefer to stay close to the muddy soil than in higher water layers. It is not surprising that they have long attracted the attention of naturalists, as they usually populate still and slowly flowing water in great crowds. The Cladoceren and Copepods make, according to Leijdig, almost the only food from the most estimated Visschen der Bavarian mountain lakes and from Lake Constance, from the Roode Trout ( Salmo salvellinus ) and Blauwe Houtingen ( Coregonus Wartmanni ), whose catch is a means of subsistence for a large number of inhabitants of the lake districts.

The Swordtails or Moluccan lobsters ( Merostomata , Xiphosuridae , Xiphuridae ) are very eccentric creatures, remnants of an extinct animal world, not closely related to any of the existing groups to be included. In important respects they deviate from the Shellfish, to which most zoologists add them, albeit with some reservations. They draw closer to the Arachnids and more specifically to the Scorpions. Unified with the latter order, they should probably form a separate class. - Long-tailed thread scorpion
With the Scorpions ( Thelyphonidae)) the three last abdominal members are narrow and form a short tube, which ends in a long, multifaceted thread with a stink gland. The whip is relatively short and 8-membered. The jaw gauges are thick, stocky and scissor-shaped at the end. The depicted species inhabits Java and Timor and is 32 mm without the tail. - Long-armed Tarantel Scorpion

Great Sea Spider - Gill foot
Gill foot Two species of these freshwater animals are found in Central Europe, Apus cancriformis and Apus productus, the latter also lives here. They can be recognized by the shape of the tail flap, which in the first species is very short and notched. Behind the shield-shaped shell, which covers the body of these animals at the back, protrudes only the long hindquarters, the last segment of which bears two long tail threads. The front part of the dorsal shield shows the two almost merging eyes. There are 30 to 40 pairs of limbs; the eleventh forms 2 brood bags for the female storage of the eggs. On the back, only the 3 whip-shaped appendages of the first pair of legs are visible. The anterior blades are small, 2-membered, filamentous, the posterior only present in the larva state. The Gill Paws live in small puddles and other stagnant water; they die when their abode dries up. The eggs, which remain in the solidified mud, retain their development capability for a very long time. [As translated online] - Garden spider

Freshwater Shrimp - Fight between an Ordinary Roller Spider and a Scorpion
The Roller Spider hides during the day in crevices of the loamy soil, in reed beds or under stones; at night she goes out for robbery and catches Insects. Tests on large specimens have shown that she also attacks large animals. A 52 mm Roller Spider. body length grabbed a 105 mm. long Scorpion at the root of the tail, bit it off and then devoured the whole animal. However, this victory was only due to chance, as it turned out, when a second Scorpio was brought to her and she attacked them from the front; this animal held its enemy with the claws and wounded it with the poison spine, to which it succumbed after a few convulsions. {trasnslated by Google] - Field Scorpion

Beach crabs - Barnacles
Barnacles They are attached to a flexible muscular stem and have a flat, three-sided shell. A large number of genera are distinguished according to the number and the greater or lesser development of the limestone plates. Among the most common are Lepas and Otion . About half of all Lepadid species attach themselves to objects moving in water, to the keel of ships, to pieces of wreckage, etc., or to animals that often change places. Anelasma squalicolaeg lives parasitically on Northern Sharks, into whose skin it has penetrated with its stem; With Lepas anserifera and a few other species, the ships are not infrequently overgrown on their return from almost all southern and tropical seas.
