OT: Wolverine Fish discovered

Hail to Hopliancistrus wolverine!

“This species has strong lateral curved spikes called odontodes tucked under the gill covers that can be extended to jab anything that tries to mess with them... Other related species in the same family, even those with big spines, aren’t known to demonstrate such behaviour. The researchers who described this species ended up with quite a few finger injuries while collecting specimens from the wild.”

yeah, this was about 25 years ago.  So they sell for that much now?  wow.

It was beatiful.  Bright deep blue eyes, and the pleco was more 'solid black' then the normal black/grey pattern they usually are.  I was kind of devestated - it was a beautiful fish.

looked exactly like this fella ....

Haha. Not something I would have expected to see on MGoBlog. This fish has been in the aquarium hobby for a while but only recently got scientifically described. 

I keep a bunch of aquariums, and specifically keep many of this family of fish (Loricariidae) and have been trying to track one of these down ever since it was described as H. wolverine, but no luck so far. One importer had them, but I wasn't ready to spend. Now I'm ready, and they're no longer available.

The spikes on the side of the face are called odontodes, and they are not always out like this. It's actually a very attractive fish IMO. 

The fish belongs to the family Loricarridae which also includes the "Pleco" that many of you know. There are hundreds if not thousands of fish in this family. Many of them have yet to get a scientific description, and instead are given an "L-number" as an identifier.  This fish was previously known as Hopliancistrus sp. "L017" but now has been given a proper description.

Pretty much all fish in the Loricarridae family have opercular odontodes like this fish that are used as a defense mechanism, however the large three prong look is specific to this species. It's pretty neat to watch them stick these out when they feel threatened.
