These lexical, grammatical, and morphological similarities can be outlined in the table below.

They noted several morphological similarities to Jibeinia but, also, distinct differences in some characters from the written description.

In view of the morphological similarities they did not support classifying the Amur cat as a species.

They share many morphological similarities with the Beryciformes, their sister order.

They are often difficult to distinguish from related species because of morphological similarities across genera.

These include the ability to create viable offspring, and morphological similarity.

The morphological similarity of all six species shows that little evolutionary change has taken place recently for these ancient fish.

They can further be subdivided in their morphological similarity to the thorax.

Thus the genus name recognised "the close relationship and morphological similarity between the two genera".

In addition to the morphological similarities, molecular studies also support a close relationship.
