Fig. 1 Gross morphological overview of colonies of Pherusella sp. a Frontal view of a mature ancestrula with a young bud on its proximo-lateral side. b Frontal view of a colony in a 4- zooid stage with several larvae and embryos developing within one zooid. c Lateral view of a protruded lophophore. d Scanning electron microscopic image of a colony in a 3-zooid stage with the ancestrula on the right side. e Scanning electron microscopic image of the remains of the larval valves on the ancestrula. f Scanning electron microscopy image of the orifice with its characteristic rectangular shape.
