Hermit crab increased prevalence of marine debris, but also due to depletion of seashells from beaches due to humans collecting them. Hermit crab species range in size and shape, from species with a carapace only a few millimetres long to "Coenobita brevimanus", which can live 12–70 years and can approach the size of a coconut. The shell-less hermit crab "Birgus latro" (coconut crab) is the world's largest terrestrial invertebrate. The young develop in stages, with the first two (the nauplius and protozoea) occurring inside the egg. Most hermit crab larvae hatch at the third stage, the zoea. In this larval stage, the

For example, the venom of the hobo spider, a common European species established in the northwestern United States and southern British Columbia, has been reported to produce similar symptoms as the brown recluse bite when injected into laboratory rabbits. However, the toxicity of hobo spider venom has been called into question as actual bites have not been shown to cause necrosis, and no such occurrences have ever been reported where the spider is native. Numerous other spiders have been
