Arthropods

1. Arthropods are basicly insects, & usually insects are earthy colours; green & brown.

grr

Arthropods are a lot more than just delicious feasts and disgusting pests. Before we go too far, we need to figure out exactly what an arthropod is.

Yes, owing to their hard chitinous exoskeleton, arthropods are compelled to shed (moult) periodically in order to grow, a process called ecdysis.

By definition all insects are arthropods - evidencing the defining characteristics of the phylum: segmented bodies, joint appendages, bodies covered by a chitinous exoskeleton. Insects (class Insecta) fall below the subphylum Hexapoda ("six legs") below phylum Arthropoda ("jointed appendages").

No. An amniotic egg is a bird or reptile egg, with a shell. Only vertebrates can have amniotic eggs. ^^

By extention, mammals also have amniotic eggs, but they're reduced in placental mammals (live birth). Platypi and echidnas still lay amniotic eggs though.

In biology the term 'analogy' is used to describe a similar feature in a different organism, which of course is possible for most of a lobster's features. In the loose sense, one might say the freshwater crayfish is analogous to the salt-water lobster.

Yes. Arthro = jointed, pod = limb or leg.

Arthropods are characterized by segmented bodies, an exoskeleton made from chitin, and jointed appendages.

Arthropoda. :P

There are four different groups of Arthropods.

The group with four pairs of legs are Spiders.

A snail would not be classified as an arthropod; it is a mollusk. A starfish, on the other hand, is classified as an echinoderm, not an arthropod either. Arthropods include organisms like insects, arachnids, and crustaceans, characterized by their exoskeletons and segmented bodies. Therefore, neither the starfish nor the snail is an arthropod.

Arthropods commonly reproduce through sexual reproduction, with fertilization typically occurring internally. Many species lay eggs, which can be fertilized before or after being laid, depending on the type of arthropod. Some arthropods, like certain insects, exhibit oviparous reproduction, while others, such as some species of scorpions, can be viviparous, giving birth to live young. Additionally, some arthropods undergo a process called parthenogenesis, where females produce offspring without fertilization from males.

Cockroaches have 13 chambers in their heart, which is a tubular structure that helps circulate hemolymph (the insect equivalent of blood) throughout their body. This multi-chambered heart allows for more efficient pumping and distribution of nutrients and oxygen, supporting their active lifestyle. The design also aids in maintaining blood pressure and adapting to varying activity levels. Overall, this anatomical feature contributes to their survival and adaptability in diverse environments.

The condition of an arthropod's coelom is referred to as a "hemocoel." In arthropods, the hemocoel functions as a primary body cavity filled with blood (hemolymph), which facilitates the circulation of nutrients and waste products. Unlike in other animals with true coeloms, the hemocoel is not lined by mesodermal peritoneum and is part of an open circulatory system.

Around 470 million years ago, during the Ordovician period, arthropods were among the dominant marine organisms. This era saw the emergence of early forms of trilobites, which were abundant and diverse, showcasing a variety of shapes and sizes. Other arthropods, such as primitive crustaceans and possibly the first arachnids, also began to appear during this time, marking significant evolutionary advancements in this phylum. These creatures played a crucial role in the marine ecosystems of the period.

Yes it is an invertebrate because it does not have a backbone.
