Electric Shock Fish

(Chismodon broweri)

Description: Distinct green filaments on dorsal and ventral sides.Pointed segments on body contain unknown metal compounds.Large eyes and mouth on oversized head.

Size: To 3 meters.

Color: Reddish body, green eyes, green filaments dorsally and ventrally.

Range: Migratory, seen only in summer in Xisle Archipelago

Habits: A nocturnal deep water fish.migrating into lagoon shallows at night. Resembles the black swallower ,( C. niger). Broweri stuns prey with a powerful electrical field generated by circular organs at the end of thin green filaments located dorsally and ventrally. Hard plated pointed body segments seem to be battery system for the storage of electrical energy. Danger to fishermen in metal boats. The electrical field surrounding this fish has been measured at 10,000 volts.

 

Hinge Back Sea Turtle

(Archelon pritchardi)

Description: Pritchardi lacks swimming flippers found in most marine turtles. Hinges adorn scutes on carapace and serve unknown purpose. All marginal scutes have single spike projecting laterally from carapace. Spikes also on rounded tail. © Bill Curtsinger © Bill Curtsinger

Size: Carapace length to 2 meters.

Color: Mostly green with copper colored costal scutes on carapace.

Range: Unknown

Habits: Illustration based on a single specimen collected from the stomach cavity of a plier fish, (Visegripitus wrenchati), by Pritchard at Kissitbibi Lagoon in 1994.Habits unknown but thought to be a shallow water resident of lagoons and estuaries. Obviously a benthic crawler, pritchardi must rise to the surface to pay off oxygen debt. Hinged scutes might aid in thermal regulation. Prey species unknown.

 

 

Megaworm (Harmeroptius trolli)

Description: Trolli appears to be an errant polychaete worm sharing characteristics with M. imoricata. Trolli is an enormous mutant with segmented body, well developed head appendage with a muscular proboscis, jaws, and teeth. It has false eyespots and long anterior spikes.

Size: Length to 2.5 meters. Can weigh up to 800 kilos.

Color: Green to blue with metallic stripes on body; red eyes; red anterior spikes

.Range :Found in lagoon and deep water sediments.

Habits: Benthic by day migrating to surface at night. Trolli is an active swimmer and crawler making brief forays onto beaches searching for mammalian prey. Naive beach campers often fall victim while sleeping. Can rejuvenate lost tissue instantly. Impossible to collect. Reproduces asexually. (P. Reinthal)

 

 

 

 

 

Plier Fish (Visegripitus wrenchati)

Description: Distinguished by large spikes mounted dorsally and ventrally on oversized head. Large eyes.

Size: Length to 2.5 meters. Can weigh up to 800 kilos.

.Range :Found in lagoon and deep water sediments.

Habits: Benthic by day migrating to surface at night. Trolli is an active swimmer and crawler making brief forays onto beaches searching for mammalian prey. Naive beach campers often fall victim while sleeping. Can rejuvenate lost tissue instantly. Impossible to collect. Reproduces asexually. (P. Reinthal)

 

 

Arrowhead Fish (Lethalactus oweni)

Description: A deep flat scaleless body, squid like tail. A tube structure along the lateral line allows fish to also swim in reverse by siphoning water forward. Rigid dorsal spines appear to be venomous.

Size: To 15 meters One fish harpooned off Isle a Hoe weighed 2 tons.

Color: Silver green to blue. Red eye bands are bioluminescent. Oweni can abruptly change color.

Range: Cosmopolitan in warm seas, common in archipelago.

Habits: This a fast offensive predator. First described by Reinthal, 1993, as voracious and a threat to shipping. Diurnal, collecting in dense aggregations along reef walls at night to sleep. Oweni is an insatiable consumer of almost everything of animal origin. Suspect in many human "shark" fatalities, although remains of victims have never been recovered. Human victims are always female.

Blue Spotted Spike Fish (VonKluginatus herbi)

Description: A long eel like fish distinguished by long dorsal and ventral spines, dorsal and ventral finlets, inferior lower jaw with large conical teeth always visible, forked tail.

Size: To 25 meters.

Color: Yellow to silver body with red spikes, green finlets, and characteristic blue spots. Adult females have small black spots above lateral line.

Range: Tropical, throughout archipelago, possibly claiming new territory beyond Xisle.

Habits: The blue spotted spike fish has the largest vertical migration of any known Xisle fish, ranging from surface to 4000 meters. A savage predator. One specimen collected off Goma Shoals had a partially digested sperm whale in it's stomach cavity. ( Personal communication Von Kluge ) Known to follow large cruise ships with high passenger counts, sinking them by thrusting spikes into hull. Herbi then attacks lifeboats, usually swallowing the entire boat with shipwreck survivors on board.
