Comb grouper (Mycteroperca fusca)<br />
Up to 85 cm long. <strong>Madeira</strong>, <strong>Canary</strong> <strong>Islands</strong>, <strong>Azores</strong>. 10 <strong>–</strong> 100 m depth.<br />
The large photo on the right shows the normal colour of the species, gray-brown with silvery spots or silvery<br />
with gray-brown spots. Occasionally, however, one can encounter yellow individuals of this species. A yellow<br />
colour in fish that usually look different („xanthochromism“) is as common in fish as is the exceptional black<br />
colour of many mammals („melanism“). The animal shown below can be recognized individually by its white<br />
spots (see also the title picture, by Pedro Monteiro). During more than 20 years, we could observe that this<br />
individual left the bay of Garajau, <strong>Madeira</strong>, around April and returned the following September or October. It<br />
is, of course, known, that many fish species perform annual migrations but it was not known that an individual<br />
fish returns to the same place every year, like a migratory bird. Photos <strong>Peter</strong> <strong>Wirtz</strong>.<br />

Blacktail comber (Serranus atricauda)<br />
Up to 35 cm long. <strong>Madeira</strong>, <strong>Canary</strong> <strong>Islands</strong>, <strong>Azores</strong>. 3 <strong>–</strong> 100 m depth.<br />
All Serranus species are simultaneous hermaphrodites, i. e. they are male and female at the same time. The<br />
Blacktail comber is one of the most common shore fish in the area. These highly intelligent fish are quite<br />
inquisitive. Juveniles may have a striped colour pattern (insert). Photos <strong>Peter</strong> <strong>Wirtz</strong>.<br />
