Biologists can classify sponges based on several key features beyond their outward appearance, including their skeletal structure, which can be composed of spicules made of silica or calcium carbonate. They also examine the arrangement and types of canal systems, which can be classified as asconoid, syconoid, or leukonoid. Additionally, the presence of specific cell types, such as choanocytes and archaeocytes, and genetic analyses can provide insights into their classification and evolutionary relationships. These features help clarify the diversity among sponge species and reduce confusion arising from their similar external forms.
Biologists do not use physical appearance alone to classify organisms. They also do not use common names, as these can be misleading and vary between regions. Additionally, biologists do not use a single characteristic or trait to classify organisms because diversity among species can make this method unreliable.

A biologist who classify organisms are called taxonomist. They are specialized in classifying organisms into groups based on behavior, structure, and origin.
No. They use the structural characteristics of the organism physically and genetically.
Because they are living animals, like starfish and sea cucumbers.
A Swedish biologist Carols Linnaeus established a simple system to classify and name organisms in 1700.
They are classified by behavior, reproduction, metabolism and appearance.
A Marine Biologist would be who you want
By their provenance, appearance, texture and mineralogy.
because structural characteristic do not change over time but physical appearance do
