Gordioidean adults are free-living in freshwater or semiterrestrial habitats and larvae parasitise insects, primarily orthopterans. [23] Unlike nectonematiodeans, gordioideans lack lateral rows of setae, have a single, ventral epidermal cord and their blastocoels are filled with mesenchyme in young animals but become spacious in older individuals.
For example (in reptiles), the coral snakes (family Elapidae) are well-known as venomous, while the non-venomous milk snakes appear visually very similar, utilizing mimicry to their advantage. If roughly stimulated or held, lasiocampid larvae are likely to writhe and lash about, forcing the stinging bristles into any vulnerable surface they can.
Dermestids have a variety of habits; most genera are scavengers that feed on dry animal or plant material, such as skin or pollen, animal hair, feathers, dead insects and natural fibers. Members of Dermestes are found in animal carcasses, while others may be found in mammal , bird , bee , or wasp nests.
Hemiptera (/ h ɛ ˈ m ɪ p t ər ə /; from Ancient Greek hemipterus 'half-winged') is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs.
Plesiomorphy, symplesiomorphy, apomorphy, and synapomorphy all mean a trait shared between species because they share an ancestral species. [a] Apomorphic and synapomorphic characteristics convey much information about evolutionary clades and can be used to define taxa. However, plesiomorphic and symplesiomorphic characteristics cannot.
"The snake's spiritual meaning has long been associated with healing and change," says Wilson. "Snakes represent the cycle of death and rebirth symbolized by the ouroboros—the snake swallowing ...
What does it mean to dream of a specific snake species, like a constrictor or rattle snake? If a very specific type of snake shows up in your dream, you can take that as a sign to research that ...
The epidermis, or outer layer, is formed of a substance called keratin, which in mammals is the same basic material that forms nails, claws, and hair. The snake's epidermis of keratin provides it with the armor it needs to protect its internal organs and reduce friction as it passes over rocks. Parts of this keratin armor are rougher than others.
