MORPHOMETRIC CHARACTERISTICS

1. Measurements :
   a) Total lengthe (tl): 173cm
   b) Mantal lenght (ml): 5.9cm
   c)Head lenght (hl) : 2.6cm
   d) Fin lenght (fl) : 4.8cm
   e) Eye diameter (ed) : 7 cm
   f) Arm lenght (al) : 2.4 cm

Specific characters grouped into different taxa

a) the body is soft covelled by mantle so henced the specimen belongs to the phylum Mullusca

b) sorrounded of the anterior portfon of the head by toot and modified into arms and tentacle so the specimen belongs to the class Cephalopoda

c) internal shell thick oral to larged cutearus and embadded in the dorsal mentale porthion finlabeface So the speciment belongs to the order Sepidae

d) outercon narrow interiors barded so the speciment belongs to the family Sepidae

e) outer narrow sthe the specimen genus sepia

f) 8 arms the specimen belongs to the species *sepia aculeata

Classification

Phylum : Mollusca 
class : cephalopoda
sub-class: sepioidea
order : dibranchia
Family : Sepiidae
Genus : Sepia 
species :***sepia aculeata***

Conclusion : From the observation of the above characteristics it may canclude that this supplied is sepia aculeata
