Baby Catshark Still Developing in its Eggcase Filmed on the Seafloor

Earlier this week, NOAA’s deep sea expedition team on board the Okeanos Explorer came across an incredible find: a baby shark still developing inside its transparent egg case. The baby shark, likely a catshark, was filmed at a depth of 820 feet (250 m) west of the Desecheo Island, an uninhabited island part of the archipelago of Puerto Rico (NOAA, 2018).

Featured Species: Scalloped Hammerhead (Sphyrna lewini)

This week’s featured species is another one of my favorite species (have you been counting how many “favorites” I have?!): the Scalloped Hammerhead (Sphyrna lewini). The first time I ever saw a scalloped hammerhead was at the Monterey Bay Aquarium in their breath taking Open Sea exhibit. The way she glided by so effortlessly with just a smooth swish of her caudal fin, and could turn on a dime…

Featured Species: Genie’s Dogfish (Squalus clarkae)

This week’s featured species was described earlier this year as a new deep water species. A paper published in Zootaxa in July of this year revealed that after DNA testing and morphological comparisons the Genie’a Dogfish was a unique species, and not a Shortspine spurdogs (Squalus mitsukurii), as previously thought (Pfleger, Grubbs, Cotton, Daly-Engel, 2018). Genie’s dogfish is characterized by…

Featured Species: Daggernose Shark (Isogomphodon oxyrhynchus)

This week’s featured species is not well known, and likely never will be, because the Daggernose shark (Isogomphodon oxyrhynchus) is critically endangered and is likely facing extinction. The daggernose shark is so named for its elongated, flattened snout, that vaguely resembles the goblin shark’s. In fact its scientific name, Isogomphodon, is Greek for “equal nail tooth” and, oxyrhynchus, for…

This Friday’s Featured Species profile is going to the flat sharks: the stingrays! The Cownose Ray (Rhinoptera bonasus) is one of my favorite species.

Featured Species Friday: Dwarf Lanternshark (Etmopterus perryi)

As Shark Fest and Shark Week come to a close I thought it might be a nice change of pace to look at a shark that you didn’t see featured in any documentary these last two weeks.

These are large, flashy species…
