Fig. 4 in Description, molecular identification and pathological lesions of Huffmanela persica sp. nov. (Nematoda: Trichosomoididae: Huffmanelinae) from the daggertooth pike conger Muraenesox cinereus

Fig. 4 Scanning electron micrographs of poorly developed (A–D) and fully developed (E–I) eggs of Huffmanela persica sp. nov. (separated from infected ovary). Less developed eggs spherical shaped (white arrow shows a shrunken and wrinkled egg) and with no evidently developed polar plugs. Fully developed eggs oblong and containing two plugs at poles. Eggs completely surrounded by a UL bearing uniformly based mammiform mounds adorned with tendril-like vermiform appendage emerging from the apex, occasionally adjoined to that of a neighboring mound (green arrowheads). Note the illusory appearance of serrated-like ridges (occasionally in the form of illusory interconnecting ridges, black arrows) in side views which is caused by overlapping of the mound bases (well observed in less developed eggs, red arrowheads). Outer surface of eggshell with irregular protuberances (yellow arrowheads)
