8) Cuttlefish, Sepiida
Cuttlefish can be found in every ocean and can swim in shallow waters or in the deeper sections (“Cuttlefish”). One of their great abilities is being able to portray one half of their body as a male and the other as a female. This can be very beneficial because if the animal is in an environment where there are too many males and not enough females the cuttlefish can show the female side to the males and the male side to the females, or vice versa. This way the other males wonÕt think it is competition and leave it be. The cuttlefish use their fins and pigment cells to mimic the sex needed (“Anatomy of a Cuttlefish”). The fins are mobile because they donÕt contain any bone or cartilaginous supporting materials. This means the cuttlefish can move and fold them to make them look like smaller, immature females (“Anatomy of a Cuttlefish”). Cuttlefish also use their 200 chromatophores (piment cells) per square millimeter to make a certain pattern and/or color to make them blend in or attract mates (“Anatomy of a Cuttlefish”). This act
