Added reference to another related post regarding the use of abbreviated names.

lh_domain (life hierarchy domain) is a parent to lh_kingdom which in turn is parent to lh_phylum - chose as many letters as you need for lh - even the full life_hierarchy_xyz... would do it - class, order... and so on down the line? No?

@J.D. Naming the table according to the direct object(s) is practical for some objects, but not all object. For example, a table named species is practical, but a table named class is not practical because it is also used in the school namespace (e.g., school_program_class)

@MichaelKutz The problem with just class or order is that they are ambiguous, because the database includes those words as its sub names, such as school_program_class.

@Vérace-getVACCINATEDNOW. Thank you for pointing out the Linnean system. I now notice the redundancy of life_. Abbreviating may be confused with other names in the namespace that also have first characters as d and p. I just updated my question to include examples of those names.

You may be interested in the public taxonomy data from itis.gov which stores all those entities in one table named hierarchy.

As pointed out by Michael, you should name a table after the direct object(s) it's data represents, regardless of where that object lives in the hierarchy of entities. Your table life_domain_kingdom_phylum_class_order_family_genus_species doesn't directly store all of the lifes, nor all of the kingdoms, nor all of the phylums, etc. It directly stored species so it should just be called species and it's foreign key relationship to it's parent entity genus (another table) should exist and explicitly define the hierarchy.

What's wrong with just phylum , class order, etc.? You have FKs that enforce the relationship. I can see a grouping (by different life groups) like worldbuilder_stackexchange_genus vs real_species

Surely those who are writing queries for this database are familiar with the Linnean system and biology in general? The life_ bit appears to be redundant. Have d_k_p as an abbreviation for domain_kindom_phylum - that should give you all the space you need? I would suggest that this is a better solution than having tables name ifuel9kf03l!
