The order lamniformes includes sharks such as the Great White Shark, Sand Tiger Shark, Thresher Sharks and Mako Sharks. Within this order is a unique type of ovoviviparity.

It can be broken down into two groups. Some of these sharks embryos use up their yolk sac and begin to feed on unfertilized eggs that the mother continues to produce. This File Size: KB. As a result, some female sharks, such as the blue shark, have skin on the back and flanks more than rays as thick as the skin of the male.

Sexual Appendages. Claspers are modified inner edges of the pelvic fins of male sharks and rays. During copulation, the erectile claspers are bent forward.

In sharks, rays, and the coelacanth, gestation takes place in the oviduct, but in teleosts, gestation occurs either in the ovarian follicle or ovarian lumen. The cystovarian teleostean ovary is hypothesized to function both as ovary and oviduct. Oviductal, ovarian lumenal, and follicular epithelial cells are the maternal sites of metabolic.

Following is a list of many of the works consulted in the research and writing of this book. This list does not pretend to be comprehensive, rather it includes those scientific works that I deem most important or interesting plus a few popular works that are both scientifically accurate and readily available.

Rays And Sharks Have Different Defensive Mechanisms. Sharks, especially larger sharks like Great White Sharks, Bull Sharks, and Whale Sharks, are apex predators and don’t have any natural predators beyond mankind. However, many sharks, fish, and whales feast on rays, so they have developed different defensive strategies.

Ashley Stoehr began her career in marine biology as an undergraduate at the University of Rhode Island where she studied the mechanics of feeding in small sharks, skates, and rays. She later received her Ph.D. at the University of Massachusetts Dartmouth studying the anatomy, physiology, and ecology of large, open-ocean fishes like.

Biology of Skates by David A. Ebert,available at Book Depository with free The reproduction and development of sharks, skates, rays and ratfishes. Leo S. Demski. 06 Dec. a standard reference work for those interested in the biology of sharks, rays and skates in general and should be accessible in all life science.

The largest sharks are not predatory. They are filter feeders. They have modifications in pharyngeal-arch. These arches capture planktons. The great white shark and the mako are most feared sharks.

Extinct specimens have reached the lengths of 15m in or more. Skates and Rays. Skates and rays are specialized for life on the ocean floor. Parthenogenesis has a further disadvantage for sharks: Through sexual reproduction, sharks can deliver up to 15 pups per litter; with parthenogenesis, in every case only one pup has been delivered.

With egg-laying species, only a few develop from a Cited by: 2. Sharks and their kin--skates and rays--have remained Of the more than shark species, 80 percent either would not hurt people, or would rarely encounter them. Sharks and their kin--skates and rays--have remained essentially unchanged for hundreds of millions of years, and their very existence is now threatened by man and his fears/5.

($) A chondrichthian (class Chondrichthyes) is any member of the diverse group of cartilaginous fishes that includes the sharks, skates, rays, chimaeras, and their relatives.

The class is one of the two great groups of living fishes, the other being the osteichthians, or bony fishes. This is a list of. Some sharks bear only one or two pups (e.g. the Great White Shark), while others bear over (e.g.

the Whale Shark and the Blue Shark) pups a season. After a gestation period (which remains unknown for most species but can extend for up to two years), live pups are born.

The issue of a common ancestor for sharks and rays becomes even more complicated when the variations between their own species are considered. (There are to species of sharks and to species of rays.5) Sharks come in all shapes and sizes, and all have incredible design features suiting their diet and environment.

The book also introduces applications of new and novel laboratory devices, techniques, and field instruments.

that viviparity first appeared in the chondies is also raised in the last big book on chondie reproduction: The Reproduction and Development of Sharks, Skates, Rays and Ratfishes. Some sharks and rays incubate the eggs in their uteruses until the baby sharks are ready to be born.

Other sharks and rays (i.e. skates) lay eggs and attach them to the reef. Sharks have between 5 and 7 gill slits on each side of their body in front of their pectoral fins. Bony fishes only have one pair.

t is not unusual for coastal communities in the Philippines to encounter whale sharks that have stranded, or are entrapped and entangled in fishing gears. There have also been documented reports of net entanglement of manta rays and even the rare megamouth shark.

Sharks, rays and skates can hunt for prey hidden in the sandy sea floor by “listening” for faint traces of bioelectricity – they can literally sense their prey’s heart beating.

The basic anatomy of the electro-sensory organs that accomplish this feat has been known for decades, but the biological mechanisms – how electrosensory cells.
