Question

I wish to know what are the taxonomic aspects necessary for the identification of certain species of poecilids, specifically what is the role in the counting of rays and spines and also the measurements of the organism. Which documents can I guide myself from? Am looking to know the exact measurements of a specific fish, in this case Poecilia salavatoris. The fish was found in Honduras, Central America in the state of Francisco Morazán in a fast-moving, shallow, seasonal brook.

Answer 1

To identify species of poecilids, taxonomic aspects such as counting rays and spines, as well as measurements of the organism, play a crucial role. For specific information about Poecilia salavatoris, you can refer to scientific literature and research papers on poecilids.

Step-by-step explanation:

When it comes to identifying species of poecilids, taxonomic aspects such as counting rays and spines, as well as measurements of the organism, play a crucial role. These characteristics help in distinguishing different species and understanding their unique features.

For the specific fish you mentioned, Poecilia salavatoris, you can refer to scientific literature and research papers on poecilids. Some documents that may guide you include:

1. Courtenay, W.R., Jr., Meffe, G.K. (1989). Small fishes in strange places: a review of introduced poeciliids.
2. Courtenay, W. R., Stauffer, J. R. (1990). The introduced fish problem and the aquarium fish industry.
3. Courtenay, W.R., Jr., Taylor, J. N. (1984). The exotic ichthyofauna of the contiguous United States with preliminary observations on intra-national transplants.

These sources can provide you with valuable information about Poecilia salavatoris and its measurements.
