Presentation Transcript

  1. Molly Miller Blenny (Scartella cristata) • Kingdom Animalia • Phylum Chordata • Class Actinopterygii • Order Perciformes • Family Blenniidae

  2. They use most of their body to generate thrust and P1 fins to stabilize on surfaces (Subcarangiform) Morphology • 1 extended dorsal fin D. XII, 14-15 • A. II, 14-17 • Short supraorbital cirri • Elongate body • No swim bladder • Jugular P2 fins • Scaleless • Terminal mouth

  3. Distribution • Atlantic coast of the Americas • African and European coast into Mediterranean • Throughout Indo-Pacific

  4. Male and Female Ecology • Maximum length of 12cm (4.75in) but usually 10cm (4in) • Inhabits 0-10m (Most dense at 2-4m) • Non-migratory, benthic, dwells in covered areas • Can change color • Sexual dimorphism by urogenital papilla in males and pronounced first anal spine

  5. Feeding Ecology • Herbivore/Detrivore • Influenced greatly by season and temperature • Prefers filamentous algaes (25-50%) • Detritus (35-65%) • Leaves “kiss marks” • Preyed upon by larger rock-outcropping predators

  6. Maturation and Reproduction • External nest builders • Eggs are adhesive • Larvae hatch at 3mm • Metamorphose at 11mm • Settlement at 11-18mm (30 days) • Mature at 4.5 months

  7. Alternative Reproduction • 3 Types of males • Nester (bourgeois) ~7.4cm • Intermediate (hole-dwellers) ~5.8cm • Sneaker (cuckhold) ~2.5-4.3cm • Some of the highest rates of progeny by non-nesters of all teleosts
