Diet of Pacific sleeper shark, a potential Steller sea lion predator, in the northeast Pacific Ocean. Spanish sea urchins (erizos de mar) are not poisonous, though if you tread on them their spikes can stick into your foot and get infected. Singles roam the beach in search of love. Spring spawning runs of the redhorses and white sucker are notable exceptions, when many are taken by bait fishing and snagging. Tough to distinguish from the Dusky Shark, but the body is fatter, the gill slits smaller, and the trailing edge of the ventral fin is indented.

On November 28, 2011, we published a notice that listing may be warranted. The Nurse shark is another saltwater shark that is not generally aggressive towards people, but unless you have a 1,000 gallon aquarium, you'd find that as pet sharks go, the Nurse shark can grow to be a bit too large to handle. The problem is pacu grow; they can get up to 90cm in length. There are striated muscles, so esophagus can stretch when swallowing. Based on these results, NOAA Fisheries changed the status of the LCS complex from overfished to unknown.

Also, their outermost teeth pointed forward which is unlike other sharks who have their teeth pointed upwards and downwards. Finally, the spiny fins of various scorpionfish, which tend to hide amongst the rocks including the Large-scaled scorpionfish (cabracho - Scorpaena scrofa ), also give painful though generally less serious stings when stepped on.

That's what the shark in the above picture is doing - feeding on plankton.

On the other hand, blue sharks share a similar diet to bull sharks. It may also protect adult and, especially, juvenile river sharks of this region against predation by the Bull Shark, which has a predilection for feeding on the young of other sharks.

Although this shark is found to a depth of 50 m (164 ft), it prefers to spend most of its time in the warm, relatively shallow water of coral reef areas, usually over sandy bottoms. Filter-feeding sharks that sift tiny plankton from the water still have teeth, but they are very small and aren’t used for feeding. You would think that the adult size of these fish would keep them out of the general aquarium hobby industry, but young, small sharks are still offered for sale to people who may not realize how big they can get.

Most of the pictures at the end of this exhibit were taken with the express intent of looking for these scars, so they may not be the most aesthetic images possible. This tissue is behind the retina and reflects light back to it, thereby increasing visibility in the dark waters. Haddock — A fish with a black stripe running along its white side. Fish, squid, shrimp, occasional live goldfish. The rows of denticles are smooth in one direction—if a shark is “pet” from head to tail—but in the opposite direction, they feel like sandpaper.
