They would come up and bump you. I was bumped a few times—you never know when they are going to attack you.” For four days those men had to stay in the water as the sharks fed first on the dead and then on the living, killing up to 150 of the shipwrecked survivors.
Why are shipwrecks preserved better in deeper water?
The deeper the wreck is located, the less the wave action affects it. With increasing depth, waves become less and less of a factor in the corrosion and decay of a shipwreck.
Are shipwrecks good for marine life?
They also serve as crucial habitats for marine life. Shipwrecks serve as seafloor features, attracting a wide variety of marine life. As different organisms colonize the ship, a stable community of diverse plants and animals emerges.
Are shipwrecks good for fish?
As warming waters destroy reef habitats, sunken remains can provide refuge for marine life.
Were there sharks when the Titanic sank?

What animals live in shipwrecks?
Hundreds of species of plants and animals, including coral, crustaceans, fish, sharks, sponges, seaweed, and anemones, can live on and around shipwrecks. Shipwrecks are teeming with a fantastic abundance of marine life.
Why do fish like wrecks?
Shipwrecks and artificial reefs host encrusting organisms, which jumpstart the food chain — drawing everything from baitfish to predators that swim throughout the water column. Tautog or grouper might be hiding inside the wreck, snapper might swim above it, and king mackerel could be chasing bait near the surface.
Why do shipwrecks attract fish?
The currents curling around a sunken structure likely push up clouds of plankton, the essential base of the ocean food web. This buffet attracts small fishes like sardines, which in turn entice sharks and other larger predators to hang around.
Do shipwrecks pollute the ocean?
Organisms living in the vicinity of the shipwreck are mainly affected but the oil can also spread to other areas with the currents. Toxic substances such as oil, polycyclic aromatic hydrocarbons (PAH:s) and heavy metals are taken up by microorganisms and transferred up the food chain to fish and crustaceans.
What happened to the bodies on the Titanic?
Where are the Titanic victims buried? Around two-thirds of the bodies recovered after the sinking were transported to Halifax in Nova Scotia, Canada for burial, whilst a third were buried at sea. 306 – the number of bodies that were recovered by the CS Mackay-Bennett (bodies 1 to 306).
