A proposed model of shark classification for extant (living) species is shown here. If a new species of shark is discovered without an anal fin and with a sawlike snout, how would this classification model be revised?
Answers
Answer:
The proposed model of shark classification would be revised to accommodate the new species of shark, and the new species would be classified based on its unique anatomical features.
Explanation:
The proposed model of shark classification shown likely classifies sharks based on the presence or absence of certain anatomical features, such as anal fin, placoid scales, gill slits, and the number of gill slits. If a new species of shark is discovered without an anal fin and with a sawlike snout, this classification model would be revised by adding a new category for this species, which shares these features.
The new category might be placed under the subclass Elasmobranchii, which is a subclass of cartilaginous fish that includes sharks, skates, and rays. The subclass Elasmobranchii is further divided into two subclasses, Selachii (sharks) and Batoidea (rays and skates). The new species of shark would fall under the subclass Selachii and could possibly form a new order or family depending on its other anatomical features, such as its teeth, jaw structure, and the number and arrangement of its gill slits. Therefore, the proposed model of shark classification would be revised to accommodate the new species of shark, and the new species would be classified based on its unique anatomical features.
