The Decorator Crab, or Collector Crab, is a marine saltwater crustacean in the Majoidea super-family with several different species.
The Decorator Crab is difficult to see in its natural habitat in tropical reefs and lagoons because it covers itself with aquatic plants and materials from its environment.
About 75% of crabs in the Majoidea super-family decorate themselves for camouflage. Some cover themselves completely and some cover themselves a little bit.

The Common Earthworm (Lumbricus terrestris) is a terrestrial (land) invertebrate (without a backbone) in the Lumbricidae family of earthworms. It is also known as the Lob Worm.
The Common Earthworm is pinkish-greyish-purple. The body is cylindrical and a tube-in-a-tube, with a series of segments, called metamerisms. The last segment is the tail, and the first segment has the mouth and prostomium (flat paddle-shaped lobe). Each segment has bristle-like hairs called lateral setae. These hairs help it to move by gripping the surface of the soil. It has pores (holes) in its body that enables it to breathe. It exudes a fluid that keeps the body moist and stops it from drying out.

How do lizards walk upside down?
Many lizards, such as geckos and skinks, can walk upside down and climb up walls. They have special toe pads that can support their weight.
Their toe pads have microscopic hairs or bristles, called setae, that act like Velcro, enabling their feet to stick to surfaces.
On each of the setae are millions of even smaller tips, called septulae. Each one can grip the surface.

The Feather Duster Worm (Sabellastarte spectabilis) is a tropical marine worm, or bristleworm – a polychaete. It is also called the Fan Worm. Some are sedentary (sessile) and some are mobile (errant). It is an annelid. It looks like a plant, but it is an animal.
The sedentary Feather Duster Worm lives in an elongated tube. The tube looks like a rolled-up parchment. It has segments that have appendages, called setae, or bristles, or tentacles, that look like a feather duster. The appendages are brown with white bands.
