Deep Sea Life




For my unit post I thought that it would be fun to look into some of the deep sea life.
Starting with.....


1. THE GIANT SQUID!!!!
The Giant Squid is no myth ladies and gentleman. It stead of thinking of it as a giant scary monster it would be more proper to refer to it as Architeuthis Dux, it's scientific n
ame. Giant squids are quite giant though and can reach up to 60ft long. Since they are mollusks they have a mantle, eight arms, and two longer tentacles, just like any other squid. All of the arms and tentacles are covered in giant suction cups that are surrounded by sharp point edges. Giant Squids are also thought to be quite the brainiacs too. Females giant squids are usually about 43 feet in length where as males are only about 33 feet. The only thing larger than the giant squid is, well, THE COLOSSAL SQUID (also known as mesonychoteuthis hamiltoni) which is a close cousin to the giant squid. Giant squids also make a tasty snack for sperm whales.



2. The Gulper Eel
The gulper eel also known as the Eurypharynx pelecanoides is not your average eel. It has a giant mouth, that can open big enough to swallow things larger than itself. They have log tails that are used for movement and are tipped with a little light. It is thought that they use this as a fishing tactic to lure in prey and then turn around, unhinge their jaws, and eat stuff. However the gulper eel has very tiny teeth so it generally preys on smaller food, but can swim through schools of fish and gulp up a good many. The gulper eel is typically found from 150 to 1,800 meters deep.


3. Giant Isopod
The giant is a carnivorous crustacean that can grow to 16 inches, which is very large compared to their 1 to 5 centimeter land buddies. It uses large antennae to crawl along the ocean floor as it scavenges for food. This giant bug thing has compound eyes and a body that can roll into a ball to protect itself. They have long legs with little hooks on the edge and like to eat dead whales, fish, and squid! Yummy! They can be found in areas 170 to 2, 140 meters deep.

4. Sperm Whales
Sperm whales large toothed whales that enjoy breathing air and diving to depths of 3,000 meters, although they usually hang around the 800 meter range. They used to be hunted largely for the oil in their blubber but now, not so much. The whales can be 67 feet long and with 63 tons. Sperm whales are generally gray and have bumpy skin, and the largest brain of any animal. They use echolocation to find food in the darkness of the deep sea. They like squid (regular, giant, or colossal) and tend to have food fights with them, as noted by the beaky scars found on dead whales. Unlike other deep sea animals that like to live alone, whales like travel in schools for the first part of their life. Although these whales can take down COLOSSAL SQUIDS they do fall victim to orca whales now and then who like to gang up on the poor sperm whales. And sperm whales are friends for life, they can live to be about 70 years old.


5. Oarfish
Oarfish are found around 200 meters usually although they have been spotted as shallow as 60 meters and as deep as 1000 meters. Oarfish are long, bony fish with bodies that resemble ribbons. They are usually a silver-blue color with a red dorsal fin that goes the entire length of the fish. They also have pelvic fins that are really long. They like to eat plankton, small squids, and other small things that they can fit in their tiny mouth.
