Spotting a Cuttlefish:
Each morning we find patches of naked tank bottom where they have hollow the night. They regularly swim about only when they are starving or investigating something in their region. This may be a tank companion a new toy, or an aquarium tourist on the other side of the glass. Spotless objects like watches and rings usually depict the most concentration.
Social behavior of squids:
Caribbean reef squid are one our preferred cephalopods. They are often encountered among superficial reefs and are usually unafraid of divers, if not curious about them. The mantle of newly hatched reef squid are about 8-9 mm in length and the mantle in adult males and females reach 12-20 cm in length. Adult reef squid closely look like their cousins, cuttlefishes, in that their bodies are extensive and less rationalized than many other squids. Reef squid can also move about using jet propulsion by shooting water from their pallial cavity (an area inside their mantle) in the course of their funnel to move quickly through the water.
The basic complexion of a Caribbean reef squid is a spotted medium green to brown on their upper side with lighter coloring on their ventral side for disguise from predators swimming above or underneath them. These animals are communal creatures often found in small groups that converse through a variety of multifaceted signals. Both cuttlefish and squid converse by controlling the pigment in their skin. Messages such as eagerness to mate, sexual recognition, and alarm are flashed through various colorful spots, blotches, and surroundings color. To signal minor alarm, their temple ridges turn bright gold and their innermost arms turn white. Their entire body will pale when a squid retreats from a latent predator and in
Because of its size and abundance, T. californicus is commonly regarded as the insect of the sea. This creature is generally very small, from 1-3 mm in size as adults. They are cylindrically shaped, and have a segmented body (head, thorax, abdomen) though no noticeable division between body regions (Powlik 1966). Each segment of the body has a pair of legs. They use their 'legs' to propel themselves through the water in short rapid jerks. They have 2 pairs of long feathered antennae, a chitin us exoskeleton and a single eye in the middle of their head, this simple eye can only differentiate between light and dark.
The outer tentacles probe for a potential meal, then the inner sensors decide if the prey is edible. They are covered in thick, blackish-brown, water-repellent fur, and have large scaled feet and a long, thick tail. This animal is by far one of the most interesting animals in the world, despite looking like a cross between a rat and an octopus. The way it behaves and utilizes its star nose is fascinating and makes it very unique when compared to other animals.

Some dive deep into the water, like a lionfish, bream, viviparous fishes of the family Scorpaenidae and Lake Baikal in some species can dive to 1000 ~ 4000 meters deep, some often floating in the upper, such as six line fish, and Lake Baikal fishes of the family. The fishes swimming are relatively slow, often hidden, not activities or bury the body in the sand, and the type of six line fish families peace Marmora subfamily is good at swimming.

I was raised in Jacksonville, Florida; “the river city” as most natives call it. As stated by the St. Johns River Water Management Disctrict the city has this nickname because it is home to the largest river in Florida, the St. Johns. The St. Johns is also one of the two rivers in the United States that flows north (2013). Since I was surrounded by it my whole life, activities involving water were very common. One of my family’s favorite things to do is have a fishing tournament for Easter on my grandparents’ dock on the St. Johns River.
Our lab manual states that dissecting a fish/squid gives anyone who has not experienced one "a chance to see just exactly what makes an organism tick on the inside and how they compare to human internal anatomy" (Mertz, Garrison and Baker 164). What is meant by this is, by becoming familiar with the essential organs and body parts of vertebrate organisms such as a fish or rat, along with those of invertebrates like a squid or crab, one can have an idea of what to expect with the anatomy of humans. While humans are not exactly the same as the said animals—particularly the fish or squid—one should at least be able to understand that since fishes are vertebrates, they are much closer to humans than squids, which lack any bones. By looking at the bones of any fish, such as the ribs or the spine of a mackerel, their structural similarities to the bones of humans and other mammals can be quite noticeable.
Soft corals such as sea fingers and sea whips, are soft and bendable and often resemble plants or trees. These corals do not have stony skeletons, but instead grow wood-like cores for suppor...
In Blackfish, Director, Gabriela Cowperthwaite, addresses the accidents that occurred at SeaWorld involving trainers and whales. Cowperthwaite’s purpose is to educate the audience on the cruel treatment and rough conditions of whales that occur in SeaWorld. The film maintains a shocking tone in order to persuade the audience and appeal to feelings of sadness and anger.
“Tentacles” by Roland Smith is the second novel in the “Cryptid Hunters” series and was released in 2009. Uncle Wolfe 's latest project is to go to New Zealand to find a giant squid, and the gigantic freighter he has rented for the trip may just be haunted. Someone on the trip is determined to sabotage their trip. Grace and Marty may just be the next victims, if they keep poking their noses into things.
The Emporer has a yellow tail and it's face can be sky or baby blue. This fish wears a black band over it's eyes and weaers it as if the fish were wearing a Batman mask all day and night. The Regal angelfish is a fish with lots of colors. It is orange but comes with blue,white,yellow and many black vertical stripes on it's two sides. There are other angelfish like the blue angelfish,half-moon angelfish,rock beauty and emporer angelfish. The bright colors of the marine angelfish help them camouflage with the majestic and beautiful colors of the ocean and help them stay alive for a decent ammount of
Coral bleaching is exactly what you're envisioning now in your head, white bleached out coral reefs which is far different from the colorful lively structures you're used to. Corals get their brilliant
Soft corals are grouped in the phylum Cnidaria, class Anthozoa, and order Alcyonacea. Their distinguishing characteristic is that their polyps always bear eight tentacles which are on both edges fringed by rows of pinnules (Fabricius and De’ath, 2002). The common name “soft coral” comes from the fact that they have no massive external skeleton as compared to the more commonly studied hard corals.
When water becomes too warm, the coral will expel the zooxanthellae, which results in the white color of the coral.
What they do is produce light (bioluminescence) that helps the squid camouflage itself at night. The squid has a special way of sensing how much moonlight is coming down, and then using a shutter, can control how much light comes out. This makes the squid not cast a shadow, making it harder for predators and prey to see it. During the day, the squid pumps out the dead bacteria, and the process starts again. What her team did was look at how these bacteria produced their light. When they were in a dilute solution with very few bacteria, then they did not produce light. But when there were many bacteria, they did produce light. The reason this happened is because the bacteria produce these chemical messengers called Quorums, which help the bacteria know how much of them there
• You need to know that fish has senses. They can hear, taste, see, and smell. They have lateral line which helps them to detect movement in water. When they are in danger, they can run away. You will really have to watch your movements because you do not want to go away with empty hands.
It seems a little bit crowded in this 20" X 13" tank that not only holds nine fish, but also two huge sea shells. Both of the pink shaded shells give the tank a happy look. There are also plastic green plants sticking out from the shells and rocks. As I am observing these objects, I am swimming back and forth in the tank. A hollow skeleton head lay upon the middle of the tank with green ferns sticking out of its eyes. An ancient, small gray pot lay next to one of the shells, also surrounded with plastic green sea plants. The thermometer sways back and forth as one of my friends hits it after swimming by.
