According to a survey conducted by The Xerces Society for Invertebrate Conservation, the monarch butterfly is facing a sharp population decline that could soon lead to its extinction. The monarch butterfly is considered the “king of all butterflies due to its extreme beauty, hence the name ”...
Invertebrate Learning and Memory RandolfMenzel, inHandbook of Behavioral Neuroscience, 2013 Conclusion Theengramof olfactory stimuli in the bee brain is characterized by its distributed nature with different prevailing processing categories at different sites. I conclude from the limited existing data that...
(Fig.5), as in sea urchins. The specification of sea cucumber mesodermal cells can be thus considered as an intermediate state between the sea urchin and the sea star and its regulatory landscape has been proposed to be that of the echinoderm ancestor [101]. Understanding how the skeletal ...
Recently, IAP homologues have also been discovered in various species of invertebrates. The invertebrate IAP homologues also contain one to three BIR domains, and some of them possess a RING finger domain. Some invertebrate IAPs were found to share the similar function with their homologues in ver...

For an invertebrate, the octopus brain is enormous. Octavia’s was about the size of a walnut—the same size as that of an African gray parrot. Alex, an African gray trained by Dr. Irene Pepperberg, learned to use a hundred spoken English words meaningfully; demonstrated an understanding of...
From those, only protozoans are able to proliferate within their hosts and therefore may be called pathogens. There are about 11,000 known protozoan species, which are parasitic to vertebrate or invertebrate hosts (O’Donoghue, 2010). Regardless of the species, the parasitic relationship depends ...
The subphylum Uniramia, which is made up of animals that belong to the classes Myriapoda and Hexapoda, contains the majority of invertebrate predators that have been used in biological control programs. Apparently, there have been no species in the Myriapoda that have been used directly to cont...
