Dorsal fin deformity
Family: Soleidae
Euryglossa orientalis
, 245 mm TL (Figure 4)
The dorsal fin of this specimen showed a deformed middle soft rays. The rays appeared clumped together,
displaced and shorter than the normal rays in the anterior and posterior parts of the fin. The deformed area showed
to be curved and extended ventrally toward the base of the fin, but did affect the dorsal side of the body. All other
fins were normal and no other abnormalities were shown.

Hyperostosis deformity
Family: Sparidae,
Argyrops spinifer
, 467 mm TL, 455 mm SL (Figure 5)
This specimens showed hyperostotic deformity, where the whole supraocciptal crest showed to be swollen having
size of 200 ×50 mm. The hyperostotic area looks like dome with a distance of 270 mm from the posterior edge of
the orbit. The sides of the hyperostotic area are all covered with scales, which appeared to be dispersed and larger
in size than those scales found below the affected area. A narrow strip of skin with disturbing and missing scales
running from the base of the hyperostotic dome and down to just dorsal to the upper edge of the orbit was
observed.
