Remora Fish and Shark Symbiosis Relation ship
Transcript of Remora Fish and Shark Symbiosis Relation ship
Shark and Remora Fish Symbiosis Relationship
A Remora fish would attach itself to a shark and use the shark for transportation and eat all the food that is left over from the shark. The symbiosis relationship between them is a commensalism relationship because the remora is getting its food and the shark gets no benefit. Studies suggest that the remoras clean parasites from the shark's teeth and perhaps skin. If the studies are true, then the relationship becomes a mutualism relationship because they both benefit from the other.
The Remora is a pelagic marine fish that is usually found in the warmer parts of most oceans sucked on to large sharks, sea turtles, bony fishes and other marine mammals
Sharks are a group of fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head
By Nick Cholula and Brandon Weissinger
Remora remora is a short, thick-set sucking fish.The Remora has 28-37 long slender gillrakers, 21-27 dorsal fin rays, 20-24 anal fin rays, and 25-32 pectoral fin ray. The dorsal and anal fins lack spines. The Remora has no swim bladder and uses a sucking disc on the top of its head to obtain rides from other animals such as large sharks, and sea turtles. The sucking disk, developed from a transformed spinous dorsal fin, contains 16-20 transverse movable lamina which create a partial vaccuum permitting the Remora to obtain rides on larger animals. The Remora grows to about 18 inches.
Shark diet depends on the species, but most species of shark eat things like fish, crustaceans, mollusks, plankton, krill, marine mammals and other sharks.
All sharks have multiple rows of teeth, and while they lose teeth on a regular basis, new teeth continue to grow in and replace those they lose. Shark ‘skin’ is made up of a series of scales that act as an outer skeleton for easy movement and for saving energy in the water. The upper side of a shark is generally dark to blend in with the water from above and their undersides are white or lighter colored, blends in with the lighter surface of the sea from below. This helps to camouflage them from predators and prey
Sharks have adapted to living in a wide range of aquatic habitats at various temperatures. While some species inhabit shallow, coastal regions, others live in deep waters, ocean floors and the open ocean. Species, like the bull shark, are even known to swim in both salt and fresh waters and deltas.Sharks have adapted to living in a wide range of aquatic habitats at various temperatures.

Human Activity Result
Humans use the Remora Fish as bait to capture larger fish in the sea. The Remora fish's habit of attatching itself to larger fish proved useful to fishermen so they can find bigger game easier. Sharks are declining due to our demand for shark food, medicines, and cosmetics.
In the future, the Remora Fish might be abused for it's fishing purposes while the sharks could decline due to their usefulness for business.
