- In 1998, Jonathan made a remarkable discovery about Basking sharks, the second largest fish on Earth.While diving with Basking sharks in the frigid waters of the Bay of Fundy, Jonathan saw parasitic lampreys on the backs of the sharks.This had never before been documented, so he returned the next year with a shark biologist and a lamprey biologist to attempt to recover living lampreys from the backs of Basking sharks.They didn't think Jonathan could do it.n 1998, Jonathan made a remarkable discovery about Basking sharks, the second largest fish on Earth.

Predator and Prey: The plight of the salamander Predator and Prey: The plight of the salamander. click to enlarge. A few years back, I had the pleasure of attending the annual meeting of the Oregon Chapter of The Wildlife Society. Among the papers presented was one titled The Effects of Stream Crossing Culverts on the Movements of Coastal Giant Salamander (Dicamptodon tenebrosus).. Essentially, the researchers were interested in the role of culverts in the distribution and genetics of the Coastal Giant Salamanders living in the Coast Range.

Bony Fishes 1 Osteichthyes account for about 96% of all fish species. Fishes not included in the Osteichthyes are the Chondrichthyes (sharks and their relatives), the Myxini (hagfishes), and the Cephalaspidomorphi (lampreys).  Living Osteichthyes are divided into three subclasses: Dipnoi, Crossopterygii, and Actinopterygii.

10 of the Most Bizarre Animal Defense Mechanisms The Pacific Ocean Hagfish has a disgusting way of defending itself. When under attack, it oozes a suffocating slime from its many pores that envelops its predator in a fatal mass of fibrous goo. The hagfish, unfortunately, sometimes falls prey to its own defense mechanism, but normally it twists itself into knots to escape the gelatinous goop.

FROGFISH The fish family antennariidae, is a distinct group of predatory fishes, with 12 genera, at least 41 species and one very special feature – their modified dorsal spine which acts as a lure for unwary prey. Mostly referred to as frogfish, 'anglerfish' would be a more accurate description of the way these creatures live, act and feed. Frogfish vary in size from five to 40 centimetres. They have loose prickly skin, limb-like pectoral fins that look like fingers and toes and an elbow-like joint.

Kloss's gibbon  [show article only]hover over links in text for more info Craniates, one of the three subdivisions of chordates, have distinct skulls-including hagfish, which have no vertebrae. Michael J. Benton comments, craniates are characterized by their heads, just as chordates, or possibly all deuterostomes, are by their tails.t has also proved difficult to produce a detailed classification within the living chordates. Attempts to produce evolutionary  family trees  give results that differ from traditional classes because several of those classes are not monophyletic. As a result, vertebrate classification is in a state of flux.

Ray-Finned Fishes (Class Actinopterygii) This separates them from the lobe-finned fishes (Class Sarcopterygii, e.g., the lungfish and coelacanth), which have fleshy fins. Ray-finned fishes make up about half of all known vertebrate species. This group of fish is very diverse, so species come in a wide variety of shapes, sizes, and colors. The ray-finned fishes include some of the most well-known fish, including tuna, cod, and even seahorses. Classification: 1  Kingdom: Animalia. 2  Phylum: Chordata.
