Notes du plongeur

Beach entry. Heavy surf (3-5 ft breaking waves near shore) and fairly strong surge. Dove the first line of reefs starting to the South of Anglin Pier. Weather was rainy. From under water, rain on the surface sounds like a million BBs bouncing on a tile floor.

I felt a little underweighted and front heavy with the steel tank and 4 lb of trim weight on tank cam band + 8 lb in the pockets. I felt like my BC was rolling from side to side and it took some time to get it to stop it. Need to tighten it better next time. Next dive with a steel HP 100 I plan to use a couple pounds of extra weight and no trim weights (all weight in BC pockets). Also need to move the BC further up the tank to not get banged in the head. SAC was 1.07, approximately.

I pulled the flag today.

Switched to octo and it breathes fine (just testing it). I need a bigger mouthpiece for it.

Derek was a good dive buddy. I learned that sea fans in South Florida are typically oriented North/South with their broad sides facing the current. Also sand lines run north south. Another nav tip was to check your compass on the surface, orient yourself, then check it again after right after you get under the water.

Also worth noting for reference that the first line of reefs starts about halfway down the pier. around where the shelter structure is.

Lire la suite During the day the nurse shark is a sluggish animal, spending most of its time resting on sandy bottoms, or in crevices in rocks and coral reefs. Often several nurse sharks may congregate when resting, sometimes even piling on top of one another . At night however, the nurse shark actively roams the sea bottom and reef for prey. It feeds on bottom invertebrates such as spiny lobsters, shrimps, crabs, sea urchins, squid and octopi . It is also feeds on fish, its nocturnal nature enabling it to prey on resting fish that would be too active during the day to capture . The nurse shark's small mouth and large pharynx enable it to feed by a unique suction method, effectively making the nurse shark the 'hoover' of the ocean floor. By cupping its mouth over a hole or crevice and expanding its throat, it creates a vacuum that sucks prey out of their hiding . This suction-feeding is also useful for extracting snails from their shells , and it will dig in sand to root out prey sensed by its fleshy barbels . The nurse shark is one of few sharks in which courtship behaviour is relatively well known . The male swims alongside the female, grabs one of the pectoral fins in his mouth, rolls her over and they mate . A large number of males will often try to mate with a single female, and females often bear numerous bite-scars and bruises received during mating attempts. It is therefore not surprising that females frequently try to avoid males by swimming in very shallow water, where they can bury their pectoral fins in the sand . Nurse sharks are ovoviviparous , a method of reproduction whereby the young develop inside a weakly-formed egg shell within the mother, receiving nourishment from their yolk sac, for five to six months . The females move to shallow seagrass beds and coral reefs to give birth to 20 to 30 pups in late spring and summer . Like many sharks the nurse shark is slow growing, with males not reaching maturity until 10 to 15 years of age, and females 15 to 20 years .
