Let ’s hear it for newly - discover species with interesting sex lifespan ! A pufferfish that ramp up complex circular spawning nest and a frog that gives birth straight to subsist tadpoles have been pick as two of the theInternational Institute for Species Exploration ’s “ top 10 ” new coinage of 2015 .
The Fish: Torquigener albomaculosus
Divers actually found the nests long before they noticed the Pisces that built them . In the mid-1990s , divers off the coast of Japan acknowledge two - m all-encompassing patterns of rippled concentric circles on the seafloor . In 2012,ichthyologists discovered the 5 - inch foresightful virile pufferfish creditworthy for the patterns . The male drop days building the rotary by dig in the moxie with its 5 and its body , then courts female in the center . After they engender , he cares for their testis until they hatch , then abandons the nest and finds a young spot to initiate dig out all over again .
The Frog: Limnonectes larvaepartus
Most frogs have external fertilization : female lie unfertilized testis and males squirt spermatozoan over and around them . But female in this new species of fanged salientian from the Indonesian island of Sulawesi keep their eggs inside their oviducts and give birth directly to tadpoles . That intend these Gaul have internal fertilization — but herpetologist are n’t quite sure how they , you know , do it , since the males do n’t have a penis - corresponding organ . A penis decidedly is n’t a requirement , as most shuttlecock manage internal fertilization just fine without one . But clearly , more inquiry is necessary .
