Tonight we're going to discuss my favorite Cephalopod, the squid--scientifically named "Teuthida." You will find squid in just about all the major bodies of water. On account of reproduction, the females ink sac is hidden from view by a pair of white nidamental glands, which lie inside of the gills. There are also red-spotted accessory nidamental glands. Both organs are associated with shells and food production for the eggs. In addition, females also have a large translucent ovary. Squids make up a great deal of the food source for birds, a variety of birds, some sharks, and even sperm whales. The squids themselves feed on small fish, crabs, and shrimp. Three interesting facts about Cephalopods are:
1. The squid as we know it today has evolved from some of the earliest known mollusks on Earth.
2. Squid sometimes feed on other smaller squid.
3. There are more than 300 species of squid.
Hope you learned something about my favorite Cephalopod!
Sea ya next time!
