FAST FACTS
Call: Pacific spiny lumpsucker(Eumicrotremus orbis
Where it lives: Northern Pacific, from Washington to Japan and north into the Bering Sea
What it consumes: Little fish, jellyfish, ctenophores, shellfishes, polychaetes
Pacific spiny lumpsuckers’small, plump bodies and lovable look make them basically wild kawaii. They are uncomfortable swimmers, so to prevent being swept by currents in their seaside homes, their pelvic fin has actually developed to serve as a suction cup, allowing them to anchor themselves to a steady surface area.
At simply 1 to 3 inches (2.5 to 7.6 centimeters) long, they are the tiniest of the 27 types of lumpsuckers, likewise called lumpfish a few of which can grow as long as 2 feet (61 cm). Lumpfish remain in the exact same order, Scorpaeniformes, as blobfish, sea robins and stonefish.
Pacific spiny lumpsuckers are little, globular fish with extra-small fins which they flap extremely to navigate. It makes them able-but-awkward swimmers. Living near the coast and dealing with the pulls of tides and strong currents, their pelvic fins are merged to form a remarkably strong sucker disc which lets them connect to rocks, coral or kelp, and, in fish tanks, even to the side of a tank.

These sucker discs are a bit terrifying to take a look at from the underside– like a lamprey with a circle of human teeth. That’s because, like our teeth, those of the Pacific spiny lumpsucker are made from enamel. The disc likewise gives off a green and yellow radiance– though the factors for this are not understood.
Males are typically red (see “worried strawberries”) and radiance red under ultraviolet light, while women are generally green to brown and do not radiance under UV rays.
When it’s time to recreate, just the males settle. They stake out an area, typically a shallow anxiety in warmer water where the women lay their eggs. The male fertilizes them and after that she leaves and he tends to and safeguards the next generation from predators.Young lumpsuckers do not yet have a defense the grownups have– rows of enamel bumps called odontodes covering their bodies, consisting of that toothy-looking circle on their undersides.
Ultimately, they will grow odontodes in spiral rows all around their bodies to secure them versus predators and accidents with rough surface areas.
