'Conus magus' ventrum 10-23mm
This is a series of shells I collected around here on Siargao Island. They're interesting because they are almost all half the usual adult size of this species, and very brightly coloured.
Nos 1-5 are plain pink with a narrow, fuzzy band of white around the middle. No 6 though, changes colours dramatically about halfway around the last whorl, and the rest of the series follows suit.
A certain Mr L A Reeve named this as Conus fucatus in 1849, but now it's generally credited as a juvenile of Conus magus which is normally about 50 cm (2") long.
Now, an interesting thing about shell collecting is that you don't often find juveniles. Shells appear to grow, wham! into their adult size in a single season. To get a series of youngsters like this is quite unusual.
So, why all these colourful shells around here?
