As big as a coconut crab. The arthropod body is incredibly successful and allows for very fast and agile creatures. The drawback of it is that, due to how it feeds oxygen to their tissues (relying heavily on diffusion), their growth is closely tied to the amount of oxygen in the air. The coconut crab is considered the largest any land arthropod can grow in ...

Personally, I've been brainstorming a race of haplo-diploidal eusocial mammalian-like humanoid aliens who, biologically, would be divided among the following 3 classes based on sex chromosome count (with cultural titles inspired by feudal European castes): Single X chromosome: Serfs, infertile workers with a child-like intelligence, whose main purpose is to ...

LOOK OUT, MAMMALS: Postulating that a large concentration of oxygen-producing plants means a warm, wet tropical climate globally, I think mammals would be in for a lot of troubles. During the Permian epoch, the proto-endothermic synapsid ancestors of mammals were the dominant life forms. After the Permian mass extinction (arguably the largest mass-extinction ...

That question has haunted my world building efforts ever since. It is my belief that the presence of a small but communal apex ...

That said, many people find eating large bugs "inconvenient" despite being both tasty and healthy because as the animal gets bigger, the shell becomes thicker and harder to get through so you are either stuck with something small ...

Depends on your hand waving First off, there are real world limitations to how much an insect can scale. Here's an excerpt from Reddit user Astrokiwi's answer to the question "If an ant was the size of a human, would it still be able to lift 10x it’s body weight?" No. This is commonly referred to as the "square-cube law". Basically, the ...

first thing to noted when you upscale small creatures such as bugs -they will need more energy source to supply it metabolism which increased along with the mass/size, the bigger creature is the more energy they needed to survive/function so if you having honeybee at size of house mouse, they will also need a lot of huge flower which could produce enough ...
