theseablog: The Remora
Ever seen a fish attached to a shark or a manta ray while they’re swimming about?
Well, these are Remoras. They have an organ on top of their head which allows them to attach to larger fish like sharks and rays to hitch rides and feed of its parasites and waste. Pretty cool adaption.

Fossil of Spiral Saw Tooth Structure of Helicoprion
There is some debate about the function and location within the body of this structure…
“The exact location of the tooth-whorl in the lower jaw is unknown. Most current reconstructions place the whorl in the front of the lower jaw; however this would create drag, making the shark a less efficient swimmer, and turbulence, alerting prey of its approach. An alternate reconstruction, created by Mary Parrish under the direction of Robert Purdy, Victor Springer and Matt Carrano for the Smithsonian, places the whorl deeper into the throat. This arrangement would be best suited for soft bodied prey…” (read more: Wikipedia)

The weird “spine and brush” structure on the back of this 375 million-year-old male Stethacanthus may have served as a sexual signaling device, making it easier for females to pick out potential mates, or was perhaps used in combat by males. Like many early sharks, Stethacanthus was only a few feet long.

Crocodile Icefish (Channichthyidae)
… a family of perciform fish found in the cold waters around Antarctica and southern South America. Water temperature can drop below 0°C (the freezing point of freshwater) in the Antarctic sea, but, stays rather constant. There are sixteen known species of crocodile icefish. They feed on krill, copepods, and other fish.
Their blood is transparent because it contains less than 10% hemoglobin and/or only defunct erythrocytes. Oxygen is absorbed directly through their scaleless skin from the water. It is then dissolved in the plasma and transported throughout the body without the hemoglobin protein. The loss of hemoglobin is not fatal because of the cold environment in which channichthyids live. Cold water has a much higher dissolved oxygen content than warmer water…

Unlike most other bony fish, boxfish have a protective covering of large, thick, joined scale plates which create an armour for protection against predators. Boxfish have the additional advantage of being poisonous to eat.
Due to this armour, boxfish can’t bend their bodies to swim or hunt. Therefore, when feeding they often blow a jet of water at the sand to expose the prey hidden beneath, and then suck it up like a vacuum cleaner.

Using its pectoral fins as shovels, the stargazer fish digs into the seafloor sand, leaving its eyes and mouth exposed to spot and eat passing prey. The fish can also produce a defensive electric shock of up to 50 volts, which it creates via a specialized organ located behind its eyes. (Photograph by Wolcott Henry; via National Geographic)

Cymothoa exigua. Probably the world’s most insidious parasite. After entering a fish’s mouth through it’s gills, it proceeds to consume and then replace the fish’s tongue. After doing so, it attaches its own body inside the mouth of the fish. Once fully attached, the fish is able to use the parasite just like a normal tongue.
