We use underwater cameras to capture footage of a white sharks dorsal fin and to identify their sex. Male sharks (like this one!) have claspers as seen in the last few seconds of this clip. Claspers are part of a male white shark's reproductive system. They are scroll shaped appendages that protrude near the shark's pelvic fin. Correctly sexing sharks is crucial to our research and providing accurate population parameters. #greatwhitesharks #greatwhitesharksareawesome #sharkresearcher #sharkrese

I am, in fact, weirded out by claspers! Claspers are male shark (and skate and ray) reproductive organs and each male shark has 2. The best way to tell if a male shark is mature is to fele its claspers. If they are bendy, he is not mature. If they are hardened (calcified) he is mature! They are so weird and gross but i respect their importance for bringing new baby sharks lol #shark #sharks #sharktok #marinebiology #marinescience #minoritiesinsharksciences #blackcreators #blackafinstem #womenins

Un subacqueo ha avuto la fortuna di assistere al passaggio di uno squalo bianco con un lato del corpo completamente ricoperto da cicatrici, dalla testa fino alla punta della pinna caudale. È un maschio di tre metri; si notano anche le due strutture riproduttive, note come claspers o pterigopodi, utilizzate per trasferire lo sperma dentro la cloaca delle femmine. Questo predatore apicale – un pesce cartilagineo stupendo – nuotava nelle acque che bagnano le Neptune Islands, in Australia. Ci sono t

When common green darners (Anax junius) are laying eggs, they are often observed in a tandem position. The male clasps the female just behind her head with his specialized claspers, ensuring they stay paired while she lays eggs. This behavior is part of mate guarding, where the male prevents other males from mating with the female during the process. The female, meanwhile, uses her ovipositor to lay eggs in or near water. She typically deposits them into aquatic vegetation, submerged wood, or so
