From the picture we can clearly see that this is a type of reptile that falls under the group known as Deuterostome. The organism is a bit small in size , it has scaly skin and also has a tail and two eyes on either side of its head and four limbs. I took this outside in my garden at home. Key characteristics would be its four limbs which would make them tetrapods which is apart of the group chordata. The organism is small in size and it has brown scaly skin. Its reproductive stuctures would be found underneath there bodies where the rear end is.
