while others and i may agree with your opinion that tetrapod like features in fish are remarkable our opinions are ultimately irrelevant unsourced promotion of opinions as well as the original synthesis novel interpretation of published material violates wikipedia's policies of neutrality due weight and no original research unless the entire list or at least the tetrapod like traits are reliably sourced e g smith lists these traits as key tetrapod characteristics the appearance is that you alone are advancing the view that all of these species and or their traits are remarkable for their supposed tetrapod like nature assertions which may never have been explicitly made in reliable sources and thus the list appears to be original synthesis the facts themselves are certainly appropriate in each species' article but combining them in a novel fashion to reach a conclusion unsupported by sources is synthesis if you're concerned that interesting behavior or anatomy is not being highlighted you might expand coverage in relevant sections of fish locomotion or diversity of fish it's fine to say something like the zob fish ventures onto land or even the zob fish is a classic textbook example of a tetrapod like fish smith but it would be synthesis and non neutral to say or imply the zob fish interestingly resembles tetrapods because it ventures onto land without any citation
