Bull. luminance counterillumination drove bioluminescent shark Cited by: Sharks of the Pacific Coast of North America. At least 34 species of sharks have been recorded off the Pacific Coast of North America. These are listed in their hypothesized phylogenetic sequence with notes on their known geographic distribution off the West Coast.

    Sharks include species from the hand-sized pygmy shark, Euprotomicrus bispinatus, a deep sea species of only 22 cm in length, to the whale shark, Rhincodon typus, the largest fish, which grows to a length of approximately 12 metres (41 feet) and which, like the great whales, feeds only on plankton through filter m: Animalia. SHARK, EUPROTOMICRUS BISPINATUS, FROM THE PACIFIC OCEAN.-On April 3, , at a night-light station occupied by the re-search vessel CHARLES H. GILBERT of the Pacific Oceanic Fishery Investigations, a female specimen of an unusual pelagic shark, Euprotomicrus bi-spinatus (Quoy and Gaimard), mm. in total length, was dipnetted by the authors.

If you look at shark attacks from our perspective, it seems that a shark is at an all you can eat seafood buffet & crosses the road to get a pizza.

The most recent comprehensive molecular phylogenies of sharks specifically address the phylogenetic relationships among shark orders (Naylor et al.,Heinicke et al., ) ().Both molecular studies reject the hypnosqualean hypothesis that places batoids within sharks (e.g. de Carvalho, ).Also, both studies support the groups Galeomorphii and Squalimorphii, previously established Cited by: Members of this group are mostly pelagic or benthopelagic and occur from near-surface waters down to over m deep.

The pygmy shark (Euprotomicrus bispinatus), the second-smallest of all the shark species after the dwarf lanternshark, is a squaliform shark of the family Dalatiidae, the only member of the genus Euprotomicrus. Their lengths are up to about 25 cm (10 in) for Class: Chondrichthyes.

Size: Maximum total length 27 cm, males maturing between 17 to 19 cm and reaching 22 cm, females maturing between 22 and 23 cm and reaching 27 cm; size at birth greater than 6 cm and less than or about 10 cm.

The lightly calcified skeleton of H. perlo, mentioned in passing by Springer and Garrick (), and shown here in Plate 2, may be an adaptation to a bathypelagic, or at least "above-bottom" mode of life, similar to that of the lightly-calcified "pelagic" shark Euprotomicrus bispinatus (see Hubbs et al., ).
