Rare Deep-Sea Anglerfish Recorded

Floating around deep-sea rocks like a watery version of French filmmaker Albert Lamorisse’s red balloon, this bulbous, brightly colored anglerfish was recorded by a remotely operated submarine camera off of California’s Central Coast in 2010.

The zebrafish,Danio rerio, is a tropical fish belonging to the family Cyprinidae. This species is a popular aquarium fish and is also an important model organism in scientific research. It has the amazing ability to regenerate fins, skin, the heart and the brain. A new study in the Journal of Neuroscience describes the role of a protein in the remarkable self-healing ability of the fish. The finding could eventually lead to ways to stimulate spinal cord regeneration in humans.
Our medicinal discoveries depend so much on the study of this kind of phenomena. Obviously we are lacking any sort of large-scale regeneration right now, but the possibilities are obviously there!

Little zebrafish can regrow its spine after injury, we learn how

Mutant Crabs Showing Up in the Gulf

BP’s massive oil spill in the Gulf of Mexico may be related to the eyeless shrimp, clawless crabs and other deformed animals now found in the Gulf, reported Al Jazeera. Fishers and marine biologists believe tremendous amounts of highly toxic chemicals may have had a negative effect on creatures that are constantly bathed in them, contrary to what BP asserts.

Al Jazeera quoted numerous fisherman who had pulled warped crustaceans from the waters where nearly 5 million barrels of oils spewed forth after the 2010 explosion that cost 11 mens’ lives on the BP-operated Deepwater Horizon oil rig.

  • “I’ve seen the brown shrimp catch drop by two-thirds, and so far the white shrimp have been wiped out,” Keath Ladner, a seafood processor in Hancock County, Mississippi told Al Jazeera. “The shrimp are immune compromised. We are finding shrimp with tumors on their heads, and are seeing this everyday.”
  • Tracy Kuhns and her husband Mike Roberts, commercial fishers from Barataria, Louisiana, found eyeless shrimp and: “We are also finding eyeless crabs, crabs with their shells soft instead of hard, full grown crabs that are one-fifth their normal size, clawless crabs, and crabs with shells that don’t have their usual spikes … they look like they’ve been burned off by chemicals.”
  • “We also seeing eyeless fish, and fish lacking even eye-sockets, and fish with lesions, fish without covers over their gills, and others with large pink masses hanging off their eyes and gills,” Darla Rooks, a lifelong fisherperson from Port Sulfur, Louisiana said.
