Understanding the behavior of manta rays: answer to a critique
Animal consciousness, especially fish consciousness, is a debated field. Very few studies focus on it, therefore critique and debate in regards to our presented results (Ari and D’Agostino 2016) was expected.
There are currently several potential roles suggested for cephalic fin movements and body turns of manta rays. As the significance of these behaviors in regards to the existence of self-awareness is uncertain, these areas of research remain to be explored further. It is undeniably questionable whether Gallup’s mirror self-recognition test is the most appropriate test to demonstrate self-awareness in manta rays or other fish species, but since this is what scientists used in previous studies, this test represents the best-known comparator for exploring the question of self-awareness in manta rays. As technological advances allow us to examine more closely the biology of teleosts and chondrichthyans, science is uncovering social, cognitive and emotional capacities that rival those...
