Long-finned Inshore Squid
Doryteuthis pealeii
Yellow, red, and brown color cells occur in its skin, with reflective streaks or patches especially along the mantle and head. After hatching, the young squid swims in the water.[2][3]
Size and lifespan
- Mantle length
- Reported size 46.5 cm[4]
Appearance
Reflective streaks or patches were seen especially along the mantle and head.[3]
In five D. pealeii individuals, yellow and brown chromatophores were collected from the dorsal mantle, while red chromatophores were collected from the ventral skin. Reflective streaks or patches were observed especially along the mantle and head.[3]
Life
After hatching, the young squid, called paralarvae, swim in the water. They have statoliths involved in balance and sensing movement.[2]
In a rearing experiment, eggs were kept under two carbon dioxide conditions. Young squid from the higher condition hatched later, had slightly shorter mantles, and had statoliths with smaller surface area and more irregular, porous shapes.[2]
Places
Observed places · Vineyard Sound[2]
Adult squid were trawled at 10–30 m for the study.
