The Selay have scaly skin and make sibilant noises in their speech. Ever since making contact with each other, the Anticans and the Selay have been mortal enemies, with the Anticans finding the taste of Selay flesh delightful and the Selay responding by attempting to capture and subdue their predators even during diplomatic occasions. Both species applied for Federation membership at the same time, in 2364. According to Captain Jean-Luc Picard, both Anticans and Selay have a passionate hatred over "matters of custom, God concepts, even, strangely enough, economic systems". Both also have been in contact with the Ferengi.
Behind the scenesEdit
Like many Star Trek: The Next Generation species, the Anticans and the Selay were designed by Andrew Probert. The creatures' design might be a joke related to them being mortal enemies, since the Anticans look like mongooses and the Selay resemble snakes.
