Annelids are a very diverse group of invertebrates which some people think of simply as worms. While all annelids are types of segmented worm, not all worms are annelids. There are more than 1,300 annelid species that we have discovered so far. Within this very large group we can find terrestrial, marine...

The Earth is full of life. Living things populate every corner of our planet, from the most populated areas of major cities to the most remote and unknown corners. This enormous diversity explains why we can find all kinds of animals with surprising behaviors and characteristics on Earth. That's why,...

Being the most diverse class of animals on the planet, insects have incredible differences in appearance when we compare one species with another. These variations apply to almost every physical aspect such as coloring, appendages, and size. While we correctly think of insects as being small in size, this...

Echinoderms are all marine-based organisms and there are about 7,000 known species with around 1,900 being different species of starfish, also known as sea stars. No species of echinoderms are known to live in fresh water, as they need...

We mostly associate flying animals with birds and we do so for good reason. The list of flightless birds is small compared to those that can fly. The opposite is true when we look at mammal species. Although there is great morphological variety in mammals, we think of them as being mostly terrestrial...

The interactions between plants and animals are very complex. Any disruptions to these relationships can be very disruptive to a given ecosystem. While the relationship between fruit-eating animals and the fruit they eat can seem straightforward, it is usually part of a very complex reciprocal relationship....

Some dog behaviors, such as mounting, can make us uncomfortable and even embarrassed. However, it is important that you do not punish or suppress your dog for these behaviors, because they are perfectly normal. What may seem strange to us is often natural behavior in dogs. We tend to anthropomorphize our...

In terms of taxonomy, it can be a little difficult to understand what constitutes a monkey. While many people will differentiate them from apes, both are part of the infraorder Simiiformes.
