Image Of the Day caption:
This sleek squid sports a futuristic tail ornament. WHOI biologist Aran Mooney and collaborators at Stanford University and the University of Michigan developed a way to attach data-logging tags to soft-bodied animals such as squid and jellyfish. The ITAG ("I" for "invertebrate") collects data on temperature, light, and animals' swimming patterns and breathing rates. It eventually detaches, floats to the surface, and relays its location, allowing Mooney and colleagues to retrieve the tag and its data. Squid and jellyfish are important to ocean ecosystems and commercial fisheries. The ITAG could help researchers better understand the animals' behaviors and responses to changing ocean conditions.
Caption from Oceanus magazine, Vol. 52, No. 1, pg. 24:
There are iPads and iPhones, and now ITAGs, electronic devices specially designed to temporarily attach to delicate, soft-bodied marine life. In this case, the I stands for invertebrate.
