Drepanopterus (SciiFii)

The whip-tailed water scorpion (Drepanopterus flagellum) is a species of eurypterid (sea scorpion) that originally lived in Canada, England, and Scotland during the Silurian and Devonian as an extinct species of Drepanopterus and the genus itself was once extinct, but has since been brought back from extinction by SciiFii and now lives in Paleozoic Park located in Downey, California. The whip-tailed water scorpion is distinguished by its "fairly large" size (with an average length of about 40 centimeters or 15 inches), compound eyes with parallel axes on a subrectangular to subovate prosoma (head). All of its legs are walking legs; the first three pairs are short and powerful, with spines; the last two pairs are moderately long, ending in strongly curved terminal claw. The last leg reaches as far as the penultimate abdominal segment. The telson ranges from styliform to clavate. As an almost fully-aquatic carnivore, the whip-tailed water scorpion feeds primarily on other aquatic invertebrates and sometimes fish. Like horseshoe crabs, the whip-tailed water scorpions lay their eggs in sand or mud and abandons them, only for the eggs to hatch about a month later.
